title: [Reversible neurotoxicity secondary to metronidazole: report of one case].
abstract: Metronidazole can cause adverse effects both in the central and peripheral nervous system. We report a 34-year-old female who presented a reversible cerebellar syndrome and peripheral neuropathy as an adverse effect associated with the use of metronidazole. Brain magnetic resonance imaging (MRI) showed hyperintense T2 and FLAIR bilateral symmetrical cerebellar lesions, without contrast enhancement or mass effect, isointense in diffusion-weighted imaging and hypointense in apparent diffusion coefficient sequences. Also, electrophysiological evaluation was consistent with axonal polyneuropathy. She had received metronidazole for a liver abscess during 49 days. After discontinuation of metronidazole, she had rapid regression of cerebellar symptoms and normalization of MRI, with subsequent disappearance of peripheral symptoms. The brain MRI, electromyography and nerve conduction studies performed at 35 months later showed complete resolution of the lesions. Although metronidazole neurotoxicity is a rare event, it must be borne in mind because the prognosis is usually favorable after stopping the drug.
