Magnetic resonance imaging in drug-induced meningitis.

Abstract

Pathologic meningeal enhancement has been reported in patients with bacterial and viral meningitis. The authors describe a 52-year-old woman with drug-induced aseptic meningitis in whom diffuse meningeal enhancement was observed with magnetic resonance imaging after administration of gadolinium diethylenediaminepenta-acetic acid. The cause and mechanism of drug-induced aseptic meningitis and the value of magnetic resonance imaging in the diagnosis of this uncommon condition are stressed.
