Description
Summary:Although schwannomas are common spinal tumors with insidious presentations, acute neurological deterioration is an extremely rare manifestation that can occur in the setting of tumor torsion and infarction. The present case reports an unusual presentation of a spinal schwannoma that underwent torsion and infarction. A 65-year-old male presented initially with acute radicular pain progressing to cauda equina syndrome and confusion. MRI of the lumbar spine revealed an intradural extramedullary lesion at the level of L1/L2 measuring 1.1x0.9 cm. Intraoperatively, a reddish mass was seen caudally twisted around itself. Gross total resection was achieved with a final diagnosis of schwannoma with areas of infarction. At his six week follow up clinical visit, the patient was asymptomatic and his neurological exam was normal. The neurosurgeon should be aware of such atypical radiographic and clinical presentation amongst the spectrum of clinical manifestation of these nerve sheath tumors.
