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.     

Spontaneous cervical epidural hematoma: Report of a case managed conservatively

Spontaneous spinal epidural hematoma is a rare cause of acute spinal cord compression. A 25-year-old male presented with a history of sudden onset of complete quadriplegia with sensory loss below the neck along with loss of bowel and bladder control. He had no history of any constitutional symptoms. He reported 10 days later. He was managed conservatively and after two weeks of intensive rehabilitation he had complete neural recovery.The spontaneous recovery of neurological impairment is attributed to the spreading of the hematoma throughout the epidural space, thus decreasing the pressure with partial neural recovery.Conservative treatment is a fair option in young patients who present late and show neurological improvement. The neurological status on presentation will guide the further approach to management.

A case of spinal circumferential acute epidural hematoma is presented. The diagnostic procedures are discussed, and particularly the interest of computerized tomography is stressed. Surgical management of this entity and prognostic implication are considered through a pertinent review of the literature.     

Spontaneous cervical epidural hematoma: case report and literature review

BACKGROUND: Spontaneously occurring epidural hematomas for which no etiology is identified are rare phenomenon. These are often neurosurgical emergencies; therefore, prompt diagnosis and treatment are paramount. Because of the rarity of this condition, we have illustrated in this recent case its presentation, evaluation and management. METHODS: A 63-year-old male presented to our emergency room with right-sided hemiparesis and contralateral hypesthesia, consistent with a C5 Brown-Séquard syndrome. An initial evaluation for cerebral infarction was unremarkable, including a negative brain magnetic resonance image. Further imaging revealed a cervical epidural hematoma of unknown etiology. RESULTS: The patient underwent emergent laminectomy for decompression and evacuation of the hematoma within 24 hours of his presentation to the emergency room. The patient's symptoms improved remarkably after surgery and a 4-month follow-up imaging evaluation revealed no recurrence of his hematoma. CONCLUSION: This report highlights the various presentations, evaluation, and management options for this rare diagnosis. It emphasizes the necessity of prompt diagnosis for possible emergent intervention.     

Spontaneous cervical epidural hematoma. A consideration of etiology

The medical literature relating to spontaneous cervical epidural hematoma has been reviewed, and two new cases have been added. In total, 43 cases have been analyzed in detail, and the authors present some new hypotheses as to the pathophysiology of this disorder.     

Spontaneous cervical epidural hematoma presenting with hemiparesis following neck extension: a case report

A 42-year-old woman suddenly developed weakness in her left extremities when stretching her neck two days after the onset of a nuchal pain. Because computed tomography (CT) of the brain did not show any apparent lesion, the patient had initially been treated as having a cerebral infarction until magnetic resonance imaging (MRI) of the cervical spine revealed a presence of a cervical epidural hematoma the next day. She was therefore transferred to our hospital, and a neurological examination showed moderate left hemiparesis, dissociated sensory loss under C6 on the right side, urinary incontinence, and left miosis and ptosis. A CT of the cervical spine demonstrated an anteriorly located left-sided epidural hematoma extending from C4 to C7. The T2-weighted MRI revealed hyperintense lesions around the gray matter on the left side that were compressed by the epidural hematoma. The patient underwent an emergent laminoplasty from C3 to C7. Although her neurological signs were consistent with Brown-Sequard syndrome, which was associated with left-sided Homer's sign, they gradually and completely subsided following surgery. The authors therefore emphasize that cervical lesions should be considered in the differential diagnosis in patients with acute onset of hemiparesis.     

Spontaneous giant intramural hematoma of the esophagus. Apropos of a case]

Spontaneous esophageal hematoma is rare, occurring in a context of high esophageal pressure with abnormalities of hemostasis in some cases. We report a case involving the whole length of the esophagus with no evidence of any etiologic factor. The value of CT Scan is reviewed comparatively with esophageal barium examination and endoscopy. CT Scan confirms the diagnosis and the absence of true esophageal perforation. The general course monitored by CT scanning is uneventful, even in the case of extensive mucosal lesions. This justifies the nonaggressive attitude advocated by the majority of authors.     

Spontaneous cervical epidural hematoma of idiopathic etiology: case report and review of literature

Context

Spontaneous spinal epidural hematoma (SSEH) is a rare idiopathic condition that leads to acute onset of neurological deficits, which if not recognized early can have catastrophic consequences. The definition and pathophysiology of this condition remain controversial. High index of suspicion followed by T2-weighted gradient echo sequences are particularly useful in early diagnosis. Management consists of prompt surgical decompression of the hematoma though a recent trend is toward non-surgical treatment.

Findings

A 70-year-old man presented with acute onset neck pain with a radicular component and rapidly progressive quadriparesis. Magnetic resonance imaging revealed a posteriorly located cervical extradural hematoma with cord compression that was promptly evacuated. Functional recovery to near normal function occurred within 24 hours of surgery.

Conclusion

SSEH in its true idiopathic form is a rare pathologic entity. Because of the high risk of poor outcome without treatment, SSEH should be a diagnostic possibility when presentation is even slightly suggestive. Prompt surgical evacuation of the hematoma leads to a favorable neurological outcome, whereas delay in treatment can be disastrous. The role of conservative management needs to be proven and should be tailored on an individual basis.     

Spontaneous resolution of tetraparesis because of postoperative cervical epidural hematoma

Background contextSymptomatic postoperative spinal epidural hematoma (PSEH) is a rare but potentially devastating postoperative complication, accounting for 0.1% to 0.2% of cases.PurposeTo describe a patient with a PSEH that completely resolved, clinically and radiographically, without surgical treatment.Study designCase report and review of the literature.MethodsA 47-year-old man with no history of a bleeding disorder underwent anterior cervical interbody fusion for C5–C6 disc herniation. The dura was exposed through removal of the posterior longitudinal ligament, and extensive decompression of posterior osteophytes of C5 and C6 vertebral bodies was performed. The patient developed tetraparesis and respiratory distress rapidly in the postanesthesia care unit and was reintubated for assisted ventilation. The computed tomography (CT) scan revealed a very large ventral epidural hematoma compressing the dural sac from C1 to C6.ResultsThe patient was prepared for hematoma evacuation. However, the neurological symptoms and respiration problems began to resolve spontaneously before the surgery was started. The hematoma was markedly improved on the follow-up CT scan, and the patient was discharged 2 weeks after surgery without neurological deficit.ConclusionsThis case illustrates that an unpredictable extensive hematoma can occur after uneventful surgery of the cervical spine in low-risk patients. In case of the dural exposure with a creation of hidden and large epidural space, the spine surgeon must pay particular attention to the possibility of a PSEH during the early postoperative period.     

Spontaneous spinal epidural hematoma

Two cases of the spontaneous occurrence of spinal epidural hematomas of the high thoracic area are reported. Both acute and subacute presentations of paraplegia are represented. Neither patient had experienced any significant antecedent trauma. No predisposing medical conditions were present. Both patients recovered to independent ambulation following timely operative intervention. The pertinent literature on spinal epidural hematomas is reviewed, and the differential diagnosis of this entity is discussed. The need for prompt diagnosis and surgical treatment to achieve the best neurological outcome is emphasized.     

Spontaneous spinal epidural hematoma diagnosed by MRI: a case report

Appropriate diagnostic procedure for spinal epidural hematomas has not been established yet. The authors reported a case of spontaneous epidural hematomas at the thoracic level, in which correct diagnosis was made with MRI and good results were obtained by surgery. A 63-year-old female experienced a severe back pain which appeared suddenly during a walk and was followed by motor weakness in both legs deteriorating quickly to paraplegia. The patient had no history of hypertension, trauma or bleeding tendency. The laboratory data were normal. On admission, neurological examination revealed flaccid paraplegia, total sensory loss below the level of Th 6 and urinary and fecal incontinence. Myelograms showed incomplete block at the Th 6 level and postmyelographic CT scan showed an isodense mass, which was suspected to be an epidural tumor located behind the spinal cord. Emergent MRI confirmed an epidural hematoma as a high intensity area extending from Th 3 through Th 11. Sixty-five hours after onset, laminectomy of Th 4 through Th 11 and the evacuation of epidural hematoma were performed without identification of the origin of the bleeding. Neither vascular malformation nor tumor was recognized during operation. Neither was it noticed on histological examination. The patient made favorable progress after the surgery. During the first two weeks in the postoperative period, she regained muscle strength enough to do standing exercise, and satisfactory improvement was made in sensory function including urination and defecation. We emphasize that MRI is indispensable to make a differential diagnosis of thoracic lesions. In the reported case, a correct diagnosis was made with MRI, and an extremely good result was obtained by an emergency operation.     

Delayed epidural hematoma. Apropos of a series of 8 cases

The authors report 8 patients who developed an epidural hematoma after having been submitted to 1 or 2 computed tomographies (CT) which did not yet show the hematoma. The initial CT was done 1 to 6 hours after the accident. The delayed hematoma was diagnosed 3 and a half hours to 7 days after the accident. Secondary clinical deterioration occurred in 6 patients and was dramatic in 4 of them. Delayed epidural hematoma seems to be a frequent event; our 8 cases represent 10 % of all epidural hematomas operated during the period under consideration. This has to be taken into account when taking care of head injured patients after negative CT. The authors propose a list of indications for repeating CT. The current views on mechanisms of formation of epidural hematomas are discussed in the light of the increasing number of reported cases of delayed epidural hematoma.
