Infiltrating spinal angiolipoma causing myelopathy: case report

We present a case of an infiltrating spinal angiolipoma demonstrating extension into the vertebral body and the spinal epidural space. The infiltration into the epidural space caused myelopathy. About 40 cases of spinal angiolipoma and angiomyolipoma have been reported; however, only a few cases have been the infiltrating type. The radiological findings were similar to those of vertebral hemangioma, but poor enhancement of the angiolipoma on contrast-enhanced computed tomographic scans differentiated between them. The infiltrating epidural tumor was removed, and the clinical symptoms improved remarkably. Total removal of the tumor and stabilization of the involved vertebral body using the anterolateral approach may be desirable when a diagnosis of angiolipoma or angiomyolipoma is confirmed preoperatively.     

Sudden onset of paraplegia caused by hemorrhagic spinal epidural angiolipoma. A case report

Spinal epidural angiolipoma is a rare benign tumor containing vascular and mature adipose elements. A slow progressive clinical course was mostly presented and rarely a fluctuating course during pregnancy. The authors report the original case of spontaneous spinal epidural bleeding resulting from thoracic epidural angiolipoma who presented with hyperacute onset of paraplegia, simulating an extradural hematoma. The patient was admitted with sudden non-traumatic hyperacute paraplegia during a prolonged walk. Neurologic examination showed sensory loss below T6 and bladder disturbances. Spinal MRI revealed a non-enhanced heterogeneous thoracic epidural lesion, extending from T2 to T3. A bilateral T2–T4 laminectomy was performed to achieve resection of a lipomatous tumor containing area of spontaneous hemorrhage. The postoperative course was uneventful with complete neurologic recovery. Histologic examination revealed the tumor as an angiolipoma. Because the prognosis after rapid surgical management of this lesion is favorable, the diagnosis of spinal angiolipoma with bleeding should be considered in the differential diagnosis of hyperacute spinal cord compression.

     

Spontaneous epidural hematoma due to cervico-thoracic angiolipoma

Epidural angiolipomas are uncommon benign tumors of the spine. Their clinical presentation is usually a progressive spinal cord compression. We report the case of a 22-year-old patient who presented with an acute paraparesis and a spontaneous epidural hematoma, which revealed a epidural angiolipoma which extended from C7 to T3. The patient underwent a C7–T3 laminectomy, in emergency, with evacuation of the hematoma and extradural complete resection of a fibrous epidural tumor bleeding. The postoperative course was favorable with regression of neurological symptoms. Epidural angiolipomas can be revealed by spontaneous intratumoral hemorrhage without traumatism. The standard treatment is total removal by surgery.     

Spinal extradural angiolipoma: a case report]

This 60-year-old man had been well until four years prior to admission, when he developed slowly progressive weakness of the lower extremities. On admission he was found to have a spastic paraparesis, sensory disturbance below the level of T10 and mild sphincter dysfunction. Conventional myelography and CT myelography demonstrated an epidural mass located from T5 to T8 vertebral level. MRI revealed that the epidural mass was fusiform and markedly enhanced by the contrast medium. Laminectomy was performed and a fibrous tumor red in color was subtotally removed. Histological findings were consistent with those of angiolipoma. Angiolipoma is a rare tumor in the central nervous system and is regarded as a clinical entity different from a spinal lipoma. Occurrence of angiolipoma in the central nervous system has been reported in 40 cases in the world literature. Thirty nine cases of them occurred in the spinal canal, especially in the dorsal epidural space of the thoracic region. The fusiform shape demonstrated in this case might also be characteristic of angiolipoma in this region.     

Spinal extradural angiolipoma: report of two cases and review of the literature

Spinal angiolipomas are benign uncommon neoplasm composed of mature lipocytes admixed with abnormal blood vessels. They account for only 0.04–1.2% of all spinal tumors. We report two cases of lumbar extradural angiolipoma and review previously reported cases. We found 118 cases of spinal epidural angiolipoma (70 females and 48 males; age range 1.5–85 years, mean 44.03) spanning from 1890 to 2006. Prior to diagnosis 40.6% of the patients had weakness of the lower limbs. The interval between the initial symptoms and tumor diagnosis ranged from 1 day to 17 years (mean 20.2 months). Except for four cases diagnosed at autopsy, 109 patients underwent surgery and gross-total resection was performed in 79 cases (72.4%). Spinal angiolipomas are tumors containing angiomatous and lipomatous tissue, predominantly located in the mid-thoracic region. All angiolipomas show iso- or hyperintensity on T1-weighted images and hyperintensity on T2-weighted images and most lesions enhance with gadolinium administration. The treatment for spinal extradural angiolipomas is total surgical resection and no adjuvant therapy should be administered.     

Spinal Langerhans' cell histiocytosis in a young adult: case report and therapeutic considerations

We report an unusual case of spinal Langerhans' cell histiocytosis of the cervicothoracic junction in a young adult man. A 17-year-old male was referred to our institution with a 3-week history of cervicothoracic pain associated to a weakness of his right upper limb. Computed tomography and magnetic resonance imaging showed a collapsed T1 vertebral body with epidural soft tissue showing mass effect on spinal cord. The patient underwent a classic anterior cervicotomy. Complete removal of the lesion could be achieved, but the soft consistency of C7 and T2 body precluded a solid anterior fixation and an extended resection of C7 and T2 body had to be performed. Then a C6 - T3 stabilisation using an anterior plate fixation and cyanomethylacrylate graft was performed. Postoperative course was uneventful. At 2 years follow-up, the patient was asymptomatic and radiological workup showed a perfect stability of anterior fixation system. Aggressive surgical management of eosinophilic granuloma should be considered in some selected cases particularly when spinal instability or neurological deficit occurs. In this young patient a modified anterior cervicotomy allowed a comfortable approach to the anterior aspect of T3 vertebra for spinal fixation.     

Spinal angiolipoma: case report and literature review

BACKGROUND/OBJECTIVE: Spinal angiolipoma (SAL) is an uncommon clinico-pathological entity. DESIGN: Single case report. METHODS: Retrospective data analysis. FINDINGS: An obese woman with a 1-year history of progressive spastic paraparesis and acute deterioration underwent magnetic resonance imaging of the thoracic spine, the results of which suggested a tumor compressing the thoracic spinal cord. The histopathological examination of the completely resected tumor revealed an epidural angiolipoma. CONCLUSIONS: This case report offers a reminder that SAL should be considered in the differential diagnosis of long-standing, slowly progressive paraparesis. It remains unclear whether an increased body mass index might be a contributing factor to the development of SAL.     

Vertebral body infarction indicating midthoracic spinal stroke

STUDY DESIGN: Case report. OBJECTIVE: To illustrate the significance of vertebral body infarction as the only confirmatory sign of spinal cord ischemic stroke. SETTING: Department of Neurology, St. Josef-Hospital, Bochum, Germany. CASE DESCRIPTION: A 65-year-old man presented with clinical features suggesting spontaneous spinal cord infarction in the territory of the left sulcocommissural artery at the level of Th 8. Sequential magnetic resonance imaging (MRI) investigations failed to demonstrate infarction of the spinal cord but T2-weighted images revealed bone marrow hyperintensities of vertebra Th 9 and 10 in their left and dorsal parts consistent with vertebral body infarction. CONCLUSION: In clinically presumed spontaneous spinal cord infarction and unremarkable signaling of the spinal cord during sequential MRI investigations vertebral body infarction may serve as the only confirmatory sign of spinal cord ischemic stroke.     

Spinal epidural angiolipoma: rare or unreported?

Three cases of spinal epidural angiolipoma, all affecting middle-aged women, are reported. Spinal epidural angiolipomas are considered a separate entity from the more common lipomas involving the same space. Although these tumors are considered very rare, the occurrence of three cases in less than 2 years in the same geographical area raises the question of their frequency. The computed tomographic scan has been misleading in two of our patients, whereas magnetic resonance imaging was highly suggestive. Two of these tumors were apparently exceptional, being lumbar and anterior. The patients were admitted with typical sciatic symptoms; one tumor eroded the vertebral body. Spinal epidural angiolipomas may go unreported because their pathogenetic potential is not fully recognized. We suggest that both magnetic resonance imaging and the operating microscope should have a more significant place in the evaluation and treatment of sciatica.     

Spinal angiolipoma: case report and review of the literature

Summary Spinal angiolipomas are rare lesions usually found in the epidural space of the thoracic spine. This report presents a case of and reviews the literature on this rare entity. The etiology, clinical presentation, imaging, and treatment are discussed. In 92 reported cases of spinal angiolipoma 56 occurred in women (61%), and 36 in men (39%). Mean age of occurrence is 42.9 years (range 10 days–85 years) with most patients presenting with slowly progressive symptoms of spinal cord compression. Most cases occur in the extradural compartment, and are of the non-invasive subtype. This rare clinical entity must be considered in the differential diagnosis of spinal epidural lesions. In most cases complete removal is possible, however, prognosis is good even for infiltrating lesions. Thus, one must not risk neurological damage to attain complete resection.     

Vertebral hemangioma extending into the spinal canal: case report

A 73-year-old woman was admitted to our hospital presenting slowly progressive hypoesthesia below the 5th thoracic dermatome and spastic paraparesis. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a mass lesion in the T3 vertebral body extending into the spinal canal. The spinal cord was compressed to the left side and right T3 and T4 nerve roots were encased in the mass lesion. One week after admission, T2-T4 laminectomy was performed to relieve the spinal cord compression. A highly vascularized tumor was observed in the epidural space at T3 and T4 levels. The tumor in the spinal canal was removed. The histopathological diagnosis was cavernous hemangioma. The patient's symptoms improved after the surgery. Asymptomatic vertebral hemangiomas are common, but its extraosseus extension causing neurologic symptoms (compressive vertebral hemangioma) is rare. The clinical symptoms, the radiological features, and the strategies for the treatment of compressive vertebral hemangiomas were discussed.     

Lumbar spinal angiolipomas: report of two cases and review of the literature

STUDY DESIGN: Case report and review of the literature. OBJECTIVES: To describe two patients with angiolipoma in the ventral aspect of the lumbar epidural space, to discuss the clinical, radiologic, and surgical features of these lesions, and to review previously reported cases. SETTING: Rome, Italy. METHODS: Two cases, a 60-year-old man and a 54-year-old woman presented with lumbar-sciatic pain but with no abnormal neurological signs. Investigation (CT and MRI) demonstrated lumbar tumours. RESULTS: Laminectomy and excision of the tumors were performed, and symptoms improved immediately. CONCLUSIONS: Magnetic resonance imaging with suppression fat sequences allows the recognition of these lesions. The prognosis after surgical removal of spinal angiolipoma is favorable.     

Modified transmanubrial osteomuscular sparing approach for resection of T1 vertebral tumor.

We report a technical modification of the classic transmanubrial osteomuscular sparing approach described by Grünenwald and Spaggiari for the treatment of a T1 vertebral tumor. The goal of the surgical treatment for spinal tumors of the cervico-thoracic area is to excise the vertebral tumor, reconstruct the spinal column, and place an internal fixation device to achieve immediate stabilization. The procedure was necessary for treating a patient who presented with an invasion of T1 vertebral body by multiple myeloma with initial neurological symptoms of epidural spinal cord compression. This approach requires a multidisciplinary team, essentially composed by the thoracic surgeon, who performs the anatomical dissection of the cervico-thoracic area, and the neurosurgeon, who performs the vertebrectomy and placement of a titanium prosthesis (Harm's cage). The operation was successful; the follow-up 6 months after the surgical procedure is normal.     

Extranodal hairy cell leukemia presenting in the lumbar spine

The authors report on a 54-year-old man who presented with a lumbar vertebral body lesion and an adjacent epidural lesion that was found to be hairy cell leukemia (HCL). The patient presented with gradual onset of back pain and intermittent lower-extremity radicular symptoms. He did not have splenomegaly or peripheral blood count abnormalities. Admission MR imaging revealed an L-5 vertebral body lesion and a lumbar epidural lesion extending from L-3 to S-2. An [18F]fluorodeoxyglucose-PET study showed numerous sites of osseous involvement. The patient underwent minimally invasive surgical biopsy sampling of the epidural lesion. Histopathological examination revealed extranodal HCL. After treatment with a 5-day course of cladribine, the patient's symptoms resolved, and at the 16-week follow-up visit there was no radiographic or metabolic evidence of disease. Hairy cell leukemia rarely involves neurological structures, but this patient responded well to standard treatment. This case demonstrates the value of tissue biopsy procedures instead of aggressive resection and the use of minimally invasive techniques to treat an HCL spinal lesion.     

Spinal extradural angiolipoma: a report of two cases and review of the literature

Extradural angiolipomas are rare tumors that can produce spinal cord compression. Two patients with thoracic spinal angiolipoma are presented that were treated with surgical resection and radiation. The histological and clinical features of the 18 previously reported cases of these tumors are discussed.     

Anterolateral approach to giant cell tumor in T4 vertebral body

A case of giant cell tumor involving the Th4 vertebral body is reported. A 27-year-old man, who had a 2 month history of back pain and paraparesis, was admitted to our department in August, 1986. On the first admission, he manifested severe paraparesis and sensory disturbance below the Th5 dermatome level. Neuroradiological examination demonstrated an epidural tumor involving the Th4 vertebral body and compressing the spinal cord. Emergency laminectomy for decompression and biopsy was performed. The surgical specimen was a giant-cell tumor. 6 weeks after the first operation, total removal of the tumor and anterior fusion of the Th 3-5 with iliac bone graft was performed through the anterolateral transthoracic approach. Postoperative course was uneventful. A curative resection and immediate stabilization was thus able to be undertaken through the anterolateral transthoracic approach, when the epidural tumor was confined to the thoracic vertebral body.     

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.     

Case of postoperative paraplegia caused by idiopathic spinal cord infarction in a young male patient

We report a case of spinal cord infarction in a 20-year-old man, who underwent abdominal surgery under general anesthesia combined with epidural anesthesia. The patient was a healthy young man with no medical history. After the operation, he complained of weakness and sensory blockade of both legs. MRI revealed spinal cord infarction at the T9-10 vertebral levels. Steroid pulse therapy was introduced, and paraplegia almost disappeared. Spinal cord infarction in a young man is very rare, but should be considered in case of postoperative paraplegia even in a young patient.     

Complete recovery of acute paraplegia due to pyogenic thoracic spondylodiscitis with an epidural abscess

Summary Pyogenic spondylodiscitis associated with epidural abscess is a rare but serious problem in spinal surgery, because it may cause a severe morbidity or mortality, if the diagnosis is established late and the treatment is inadequate. A case of pyogenic thoracic spondylodiscitis associated with epidural abscess whose symptoms progressed over two months from back pain to acute paraplegia was presented. Magnetic resonance imaging of the spine suggested the presence of T9–10 spondylodiscitis with partial destruction of the T9 and T10 vertebral bodies and concomitant epidural abscess. Treatment consisting of surgical debridement of infected vertebrae and disc material, fusion and anterior spinal instrumentation was performed. Microbiological culture of the material revealed infection with Staphylococcus aureus and after 3 months of antibiotic treatment, recovery was almost complete. Based on a thorough review of the literature and the case presented in this report, it is concluded that accurate and prompt diagnosis requires high index of suspicion followed by a combination of adequate surgical and conservative treatment prevents severe morbidity in cases of nonspecific pyogenic spondylodiscitis associated with epidural abscess.
