Isolated Angiitis of Cntral Nervous System: A case Report

ABSTRACT

Isolated angiitis of central nervous system is a rare clinicopathologic entity characterized by vasculitis restricted to the vessels of the central nervous system without other apparent systemic vasculitis. We report a 57-year-old female patient who had suffered from repeated episodes of headache, vomiting and mental confusion. There was no evidence of systemic vasculitis. Brain CT scan showed multiple infarcts, and CSF showed mild pleocytosis and increased protein level. Cerebral angiogram confirmed the diagnosis by revealing multiple narrowing of small and medium sized arteries. Steroid and cyclophosphamide were tried with apparent benefit. Literatures are briefly reviewed.
