Spinal cord vasculitis presenting as a spinal cord tumor in a heroin addict

Abstract

✓ Progressive quadriparesis in a heroin addict was diagnosed on the basis of clinical and myelographic findings as an intramedullary cervical spinal cord tumor. A biopsy of the enlarged cervical spinal cord showed myelomalacia, vasculitis, and many doubly refractile bodies in the parenchyma and vessel walls.
