Paraneoplastic subacute necrotic myelopathy.

A 79 year old male acutely developed a Brown-Sequard syndrome two weeks following resection of renal cell carcinoma. The subsequent clinical course was marked by subacute progression of spinal cord signs. Pathologic studies showed extensive multifocal spinal cord necrosis that could not be attributed to vascular occlusion or to vasculitis. This case appears to be a rare example of paraneoplastic subacute necrotic myelopathy.
