Long-term Implication of Metronidazole Induced Reversible Cerebellar Toxicity and Peripheral Neuropathy- A Case Report

Metronidazole Induced Encephalopathy (MIE) is rare and serious central nervous system toxicity. A 40-year-old male, on long-term self treatment with metronidazole (cumulative dose: 102 gm) presented with dysarthria, nystagmus, unsteadiness, and numbness in both legs.

Summary:Metronidazole Induced Encephalopathy (MIE) is rare and serious central nervous system toxicity. A 40-year-old male, on long-term self treatment with metronidazole (cumulative dose: 102 gm) presented with dysarthria, nystagmus, unsteadiness, and numbness in both legs. A Magnetic Resonance Imaging (MRI) scan of the brain revealed a symmetric hyperintensity in both the dentate nuclei of cerebellum on both T2 weighted and Fluid-Attenuated Inversion-Recovery (FLAIR) imaging. Discontinuation of metronidazole resulted in resolution of the imaging findings and clinical improvement occurred within one month. Metronidazole-induced neurotoxicity should be considered in patient who present with cerebellar symptoms and characteristic lesion on MRI in close temporal relation with metronidazole intake and drug should be discontinued to prevent permanent neurological deficit.
