Case 271: Metronidazole-induced Encephalopathy
Abstract
Characteristic signal abnormality in the cerebellum and brainstem in a patient who has been on a prolonged course of metronidazole that subsequently resolves at follow-up imaging is diagnostic for metronidazole-induced encephalopathy.
History
An 11-year-old boy taking oral antibiotics for Fusobacterium meningitis diagnosed 3 months earlier presented to the emergency department with a 1-week history of intermittent emesis, dizziness, and vertigo and a 1-day history of wobbly gait and bilateral lower extremity paresthesia without confusion. His metabolic profile was normal. Contrast material–enhanced MRI of the brain was performed.
