Spinal cord involvement as the presenting symptom of acute monocytic leukemia

Spinal cord involvement in leukemia is rare and has been described only once in association with acute monocytic leukemia. A patient whose presenting symptom of acute monocytic leukemia was the syndrome of cauda equina compression due to an epidural and retroperitoneal leukemic mass is reported. Peripheral blood smears were normal throughout the evolution of the disease. The radiological, surgical, and pathological findings are presented, and the therapeutic, along with the prognostic implications of spinal cord involvement by leukemia are discussed.     

Recurrent idiopathic epidural hematoma: a case report

Spinal epidural hematoma is a relatively rare condition in children. We report the case of a 6-year-old girl who presented to a regional hospital with the complaints of severe thoracic back pain, neck stiffness, and gait disturbance of sudden onset. Clinical examination revealed no obvious cause for the symptoms. Spinal magnetic resonance imaging (MRI) revealed the presence of an epidural mass lesion extending from T1 to T3, compressing the spinal cord; the findings suggested a diagnosis of idiopathic spinal epidural hematoma. Twelve days after admission, the patient was transferred to our hospital for further observation. Blood tests, including a coagulation profile, were normal. At 22 days after the initial presentation, repeat MRI revealed resolution of the hematoma, with the mass showing an appreciable decrease in size. The patient became symptom-free and was walking normally at the time of discharge 28 days after her initial presentation. At 59 days after the initial presentation, she was readmitted with complaints of a sudden recurrence of back pain and weakness of both legs. Repeat MRI at this time revealed reappearance of the spinal epidural hematoma at the same level. Operative evacuation of the hematoma was performed 3 days after the diagnosis of the recurrence, with laminoplasty from T1 to T3. At a clinical review conducted 30 months after the operation, the patient remained symptom-free. Idiopathic resolution of a spinal epidural hematoma has previously been reported in 36 patients. However, we found no record in the literature of any case in which an epidural hematoma recurred following earlier MRI-confirmed idiopathic resolution.     

Myelopathy due to epidural varicose veins of the cervicothoracic junction. Case report

A 30-year-old man presented with a subacute course of myelopathic signs and symptoms. Magnetic resonance imaging demonstrated an epidural mass lesion of the spinal canal at the cervicothoracic junction causing compression of the spinal cord. Laminectomy with resection of this lesion revealed a large varix with acute and chronic thrombus. Postoperatively, an improvement in neurological function occurred. Spinal epidural varicosities have been reported as an etiological factor in lumbar and sacral radiculopathies. This is the first reported case of spinal cord compression in association with spinal epidural varices. The diagnosis, pathophysiology, and management of this disorder are presented.     

Spontaneous spinal epidural haematoma causing rapid flaccid paraplegia in a healthy 25-year-old patient

Although clinical presentation of a spinal epidural compressive haematoma is well recognized, causing acute radicular pain shortly followed by cord compression syndrome, its aetiology may pose a quandary. Rare and most commonly seen after trauma, spinal surgery, epidural anaesthesia, anticoagulation therapy, vascular malformation or coagulopathy (haemophilia), spinal epidural haematoma (SHE) can be spontaneous. Surgical decompression remains the mainstay treatment especially when the prognosis depends on the interval to surgery and the severity of preoperative neurological deficit. We report the case of a healthy 25-year-old man who presented, three days after an acute back pain, a flaccid paraplegia with urinary retention. Magnetic resonance imaging of the spinal column identified a compressive SHE extending from T3 to T6, requiring an early laminectomy. After decompression, clinical outcome revealed a complete recovery excepted some mild sensibility trouble remains.     

Delayed epidural hematoma after spinal surgery: a report of 4 cases

Symptomatic postoperative epidural hematoma is a rare and potentially devastating complication of spinal surgery. The overwhelming majority of reported cases have occurred in the immediate postoperative period. A recent publication defined the clinical entity of delayed postoperative epidural spinal hematoma as neurologic deterioration due to an epidural hematoma occurring at least 3 days after the index procedure. Only 2 such cases have been reported in the lumbar spine to date. Four cases of delayed postoperative spinal epidural hematoma were identified over a 6-year period among the spine surgeons at a single large academic institution. Each case involved the lumbar spine. The details of each patient's initial surgery, presentation, and hospital course were then gathered from a retrospective chart review. The 4 patients presented are unusual in their delayed symptomatic presentations of postoperative spinal epidural hematoma. Despite the longer time to onset, however, our patients exhibited many of the characteristics common to cases that presented in the acute postoperative period. The spine surgeon must remain vigilant for the possibility of postoperative spinal epidural hematoma in at-risk patients, even weeks after the original surgical procedure.     

Chronic lumbar epidural haematoma presenting with acute paraparesis

Summary ¶Chronic spinal epidural haematomas are very rare and have been reported to occur only in the lumbar region. They usually become symptomatic through radicular pain or neurogenic claudication. The epidural bleeding is thought to originate from a rupture of an epidural vein due to a sudden increase in intra-abdominal pressure or due to trauma.The patient reported on here developed acute paraparesis about 8 weeks after a mild fall on the buttocks. MRI showed a spinal epidural mass located dorsolaterally at the level of L3–L5. The mass was surgically removed. Histological and immunohistological studies disclosed an organised haematoma.The clinical, radiological and intra-operative features of this case are described, and the relevant literature is analysed.Published online October 20, 2003     

Spontaneous cervical epidural hematoma

The authors report a case of spontaneous cervical epidural hematoma in a 13-year-old boy who exhibited hematoma recurrence 3 years after the first incidence. A review of the literature indicates very few reports of the recurrence of spinal epidural hematoma.     

Tumoral calcinosis in the upper cervical spine causing progressive radiculomyelopathy--case report

A 54-year-old woman with chronic renal failure presented with tumoral calcinosis manifesting as progressive radiculomyelopathy. Magnetic resonance imaging revealed a spinal epidural mass in the C-2 to C-4 levels. The clinical and radiological findings suggested malignant tumor. Resection of the lesion was performed with total C-2 laminectomy and C-3 and C-4 laminoplasty. The symptoms totally disappeared after surgery. The histological diagnosis was tumoral calcinosis. Tumoral calcinosis is a rare tumoral calcium pyrophosphate dihydrate crystal deposition disease which presents as periarticular soft tissue calcification. Tumoral calcinosis should be considered in patients with a mass lesion involving the upper cervical spine and associated with metabolic abnormalities. Surgical excision is the treatment of choice, because this is completely curative without known recurrence.     

Spontaneous acute thoracic epidural hematoma causing paraplegia in a patient with severe preeclampsia in early labor

This is a case of acute spontaneous thoracic epidural hematoma in a laboring patient at term who presented with severe preeclampsia and acute spinal cord compression, paraplegia, and sensory loss below T8. In early labor, at home, the patient experienced sudden lumbar back pain that progressed to mid-scapular pain leading to paraplegia and T8 sensory loss within one hour of onset of pain. Her symptoms were caused by a spontaneous thoracic epidural hematoma. Upon arrival at the first hospital, the correct presumptive diagnosis was made in the emergency room, magnesium sulfate was administered, and the patient was transferred to our medical center. Her hypertension was not treated despite severe preeclampsia in order to maintain spinal cord perfusion pressure. Following cesarean section under general anesthesia, thoracic laminectomy was performed and an epidural hematoma compressing the spinal cord to 2-3 mm was evacuated 13 h after the onset of symptoms. After approximately three months of paraplegia, five months with quad-walker and cane use, the patient can now walk with a cane or other minimal support but has remaining bowel and bladder problems. The conflicting anesthetic management objectives of severe preeclampsia and acute paraplegia secondary to spinal epidural hematoma required compromise in the management of her preeclampsia in order to preserve spinal cord perfusion.     

Lumbar spinal angiolipoma: case report and review of the literature

Spinal angiolipomas are extremely rare benign tumors composed of mature lipomatous and angiomatous elements. Most are symptomatic due to progressive spinal cord or root compression. This article describes the case of a 60-year-old woman who presented with a 6-month history of low back pain radiating to her right leg. The pain was multisegmental. The condition had worsened with time. Lumbar magnetic resonance imaging revealed a dorsal epidural mass at L5 and erosion of the lamina of the L5 vertebra. Laminectomy was performed, and an extradural tumor was totally excised. Neuropathologic examination identified it as a lumbar spinal angiolipoma. There was no evidence of recurrence in follow-up 12 months later. This rare clinical entity must be considered in the differential diagnosis for any spinal epidural lesion.     

Hemorrhagic lumbar facet cysts accompanying a spinal subdural hematoma at the same level

Context

We present a rare and interesting case of hemorrhagic lumbar facet cysts accompanying a spinal subdural hematoma at the same level suggesting a possible mechanism by which spinal subdural hematomas can arise.

Findings

A 71-year-old man presented with persistent sciatic pain and intermittent claudication. Magnetic resonance imaging demonstrated a multilocular mass lesion that showed high signal intensity in both T1- and T2-weighted images, and was located both inside and outside of the spinal canal. Computed tomographic myelography showed a cap-shaped block of the dural tube at L5 and computed tomography with L5–S facet arthrography demonstrated cystic masses. The patient was diagnosed with lumbar radiculopathy caused by hemorrhagic facet cysts, and then progressed to surgical treatment. Surgery revealed that the cysts contained blood clots, and intraoperative findings that the inside of the dural tube appeared blackish and that the dural tube was tensely ballooned after removal of the cysts led us to explorative durotomy. The durotomy demonstrated concentrated old blood pooling both in the dorsal and ventral subdural space, and these spaces were subsequently drained. After surgery, his sciatic pain and intermittent claudication resolved. There was no evidence of cyst mass recurrence at 2 years of follow-up.

Conclusion

We propose a newly described mechanism for the formation of spinal subdural hematomas. We recommend surgeons be alert to epidural lesions causing repeated acute compression of the dural tube, which can cause spinal subdural hematoma, and consider the possible coexistence of these lesions in diagnosis and strategic surgical decisions.     

A single spinal lesion arising from an intradural meningioma contiguous with an extradural lymphoma

The authors describe here a unique case of contiguous, synchronous meningioma and lymphoma in the spinal column. Both tumors were present at the same vertebral level, one intradural and the other extradural. A patient presented with bilateral leg pain, acute weakness, and sensory loss in the lower extremities. Magnetic resonance imaging revealed an intradural mass at T6-7 with ambiguous boundaries relative to the thecal sac and compressing the spinal cord. The patient underwent resection of the epidural and intradural mass at T6-7. Histopathology revealed the epidural specimen to be a double-hit B-cell lymphoma and the intradural mass to be a transitional meningioma. Postoperatively, the patient did well, with an immediate return of strength and sensation. A postoperative MR image showed complete resection of the intradural mass. The authors suggest that biopsy may be prudent in patients with known systemic lymphoma presenting with a spinal lesion that has unclear boundaries relative to the thecal sac prior to commencing radiation and chemotherapy.     

Surgical experience of gas-containing disk herniation

Disk herniation with gas or gas-containing disk herniation (GCDH) is rare, although epidural gas is associated with the vacuum phenomenon. The clinical, radiologic, and surgical findings were retrospectively analyzed of 18 patients with GCDH. The demographic, clinical, and radiologic findings including computed tomography and magnetic resonance imaging, as well as operative methods were examined. The mean age was 64.4 years (range 51-84 years). All patients presented with acute radiculopathy or exacerbation of chronic pain associated with GCDH of the lumbar spine. All lumbar GCDHs were related to the vacuum phenomenon. Ruptured disks predominantly compressed the nerve root with gas in 17 cases, except in one with only compressed nerve root by gas without disk herniation. All patients had confirmed GCDH at surgery. All patients underwent removal of GCDH and five with another level of spinal stenosis or disk herniation underwent selective decompression. The six patients with instability underwent fusion. Visual analogue scale score of radicular pain was improved from 7.4 ± 0.9 before surgery to 3.2 ± 0.7 at the 3-month follow-up examination. No recurrence occurred after surgery. GCDH can occur as a space-occupying lesion in epidural space as well as a cause of radiculopathy. GCDH may indicate the source of clinical symptoms in the degenerative spine, especially combined with spinal stenosis or multiple spinal disk herniations.     

Recurrence of severe hypophosphatemia associated with tumor neogenesis in a patient with acute lymphocytic leukemia who experienced acute renal failure due to tumor lysis syndrome

We report a 47-year-old male patient with acute lymphocytic leukemia (ALL) who showed recurrent severe hypophosphatemia. Chemotherapy for ALL induced tumor lysis syndrome requiring hemodialysis therapy. Thereafter, severe hypophosphatemia (serum phosphorus concentration less than 0.7 mg/dL) was observed several days before an acute rise in peripheral lymphoblast cell counts due to recurrence of ALL. This hypophosphatemia soon returned to a higher than normal level by treating leukemic cells with anti-cancer agents. This event occurred twice in his clinical course. The laboratory tests strongly suggested that this hypophosphatemia was induced by a shift of phosphorus into leukemic cells that rapidly replicated in the tissues.

Abstract：

Objective To evaluate the outcome of combination of intensive preconditioning regimen allo-HSCT with imatinib for treatment of Ph chromosome positive acute lymphocyte leukemia (ALL). Methods Between 2009 and 2010, 8 patients diagnosed as Ph+ ALL received allo-HSCT from HLA identical sibling during complete remission. Imatinib was added into the therapies of 5 patients.Seven patients received the intensive preconditioning regimen based on BuCy2, one patient received the regimen of TBI-Cy. A median of 6. 02 × 108/kg mononuclear cells and 3. 14 × 106/kg CD34+ cells were transfused. GVHD prophylaxis included cyclosporine A and methotrexate. Results All patients were well tolerant to the regimen without serious regimen-related toxicity. The median time of ANC≥0. 5 × 109/L was 15. 5 days, and that of PLT≥20 × 109/L was 19 days. Thirty days after allo-HSCT, all patients got donor engraftment successfully. Among 8 cases, 4 cases presented acute GVHD, 2 developed degree Ⅰ , one developed degree Ⅱ , and one developed degree Ⅳ. Seven patients were alive 100 days after allo-HSCT, 3 of whom presented chronic GVHD. At the end of following-up period, 6 patients were alive, among them, 3 patients were alive without relapse; 3 patients relapsed; Two patients died, one from acute GVHD, and one from leukemia relapse. Conclusion Combined intensive preconditioning regimen allo-HSCT with Imatinib was an effective treatment for Ph+ ALL, but the effect of anti-chronic GVHD of imatinib should arouse certain attention.     

Multilevel acute spinal epidural hematoma in a patient with chronic renal failure--case report

A 47-year-old female with diabetic nephropathy presented with acute onset of severe back pain and progressive weakness in both lower extremities. Neuroimaging revealed a spinal epidural hematoma extending from the T-3 vertebra to the sacrum. Removal of all or every other lamina on levels with epidural hematoma and emergent evacuation of the hematoma were planned. T-9 and T-10 laminectomies were performed, but excessive bleeding during the operation prompted us to abandon the procedure. Plasma and desmopressin administration controlled the bleeding from the drain 8 hours after the operation. Follow-up neuroimaging one month later revealed total resolution of the hematoma with improved neurological status. Acute spinal epidural hematomas extending over more than 15 segments are extremely rare and the surgical treatment is still challenging. Coexisting hemorrhagic diathesis creates more problems. Conservative treatment may be the best option.     

Castleman's disease and spinal cord compression: case report

OBJECTIVE AND IMPORTANCE: Castleman's disease is a rare lymphoproliferative disorder most often found in the mediastinum. Localized forms are usually benign, whereas multicentric forms may be aggressive. We report a patient with Castleman's disease who presented with spinal cord compression, and we review previously published cases of Castleman's disease involving the central nervous system. To our knowledge, this is only the second case of Castleman's disease presenting as a spinal epidural mass with cord compression. CLINICAL PRESENTATION: A 44-year-old otherwise healthy woman presented acutely with difficulty walking. Examination revealed mild myelopathy in her legs. Magnetic resonance imaging revealed a posterior epidural mass compressing the thoracic spinal cord at T3-T5. INTERVENTION: Thoracic laminectomy and gross total resection of the lesion were performed. Pathological examination of the lesion identified the hyaline-vascular type of Castleman's disease. The patient's symptoms resolved postoperatively. CONCLUSION: Castleman's disease presenting as a spinal epidural mass lesion with cord compression is rare. Surgical treatment can result in an excellent outcome.     

Epidural inflammatory pseudotumor in the thoracic spine in a patient with polymyalgia rheumatica

Background contextOnly six previous cases of epidural inflammatory psedotumor in the spine have been reported. None of them were seen in the course of polymyalgia rheumatica (PMR).PurposeTo describe a rare case of epidural inflammatory pseudotumor in the thoracic spine in a patient with PMR.Study designCase report.MethodsA 63-year-old man had a 6-year history of PMR treated with prednisone and cyclosporine. He presented with gait disturbance. Magnetic resonance imaging on the 12th day after the onset of the symptoms showed spinal cord compression caused by a posterior epidural mass at the T5–T6 level.ResultsThe patient underwent a T5–T6 laminectomy and a total excision of the mass, which involved the ligament flavum and epidural adipose tissue and firmly attached to the dura mater. Histopathologic examination revealed severe lymphoplasmacytic infiltration with fibrosis in the entire specimen and no evidence of hematomas or tumorous lesions. After surgery, the patient's neurologic symptoms disappeared immediately. Two years after surgery, the patient is neurologically normal and has not had a recurrence.ConclusionsThis report identifies a rare case of epidural inflammatory pseudotumor in the thoracic spine in a patient with PMR.     

Acute leukemia: an association with atypical hemolytic uremic syndrome

A 5-year-old boy was admitted for anemia, thrombocytopenia, and azotemia. Bone marrow examination demonstrated only erythroid hyperplasia, and he was diagnosed with an atypical form of hemolytic uremic syndrome (HUS). He was treated with daily prednisolone, and hematological profiles and renal function normalized 1 month later. However, heavy proteinuria persisted, and renal biopsy findings were consistent with HUS. Four months later, pancytopenia developed with recurrence of azotemia, and a second bone marrow examination revealed acute lymphoblastic leukemia (ALL). The remission of proteinuria with no recurrences of HUS after antileukemic treatment suggests that the HUS was associated with the ALL.     

Thoracic spinal epidural abscess caused by Salmonella typhi

A 56-year-old man presented with a rare spinal epidural abscess manifesting as attacks of back pain associated with fever, weight loss, generalized weakness and fatigability, and constipation. He had multiple skin pustules in the last 4 months treated with oral amoxicillin. He had suffered diabetes mellitus for the last 5 years and was insulin dependent. Physical examination found slight paraparesis with sensory loss around the nipple and sphincteric urgency, and diabetic retinopathy. Magnetic resonance imaging showed edematous T2, T3, and T4 vertebral bodies, and narrow enhanced T3-4 disk space with a soft tissue enhanced mass mostly anterior to the spinal cord and indenting the cord. T3-4 costotransversectomy was performed to remove the extradural mass and evacuate the intradiscal material. Histological examination of the bone found osteomyelitis, and culture of the soft tissue showed Salmonella typhi sensitive to ceftriaxone and ciprofloxacin. Intravenous ceftriaxone administration was started, and the patient was discharged after 6 days in good condition. The outcome of spinal epidural abscess is devastating unless recognized and treated early. The present case of spinal epidural abscess in the thoracic spine caused by Salmonella typhi infection illustrates the importance of cultures to assess the drug sensitivity of the specific strain detected and adjusting the treatment accordingly.
