Temporal arteritis: cerebrospinal fluid and brain scan abnormalities (case report).

A 61-year-old man presented with a syndrome suggesting temporal arteritis. Abnormal radioisotope brain scan and cerebrospinal fluid (CSF) findings were consistent with a diagnosis of intracranial vasculitis. Although the clinical response to steroids was dramatic, improvement in the CSF abnormalities lagged. Nevertheless, persistent use of steroids in high dosage resulted in normalization of both CSF and brain scan abnormalities.
