Metronidazole-induced encephalopathy in a patient with spondylodiscitis

Introduction Metronidazole-induced encephalopathy is an uncommon but potentially severe complication of metronidazole treatment. Although the exact pathophysiology remains elusive, proposed hypotheses include RNA binding, neurotoxicity from free radicals, and modulation of neurotransmitter receptors. Most cases demonstrate improvement upon discontinuation of metronidazole, highlighting the importance of early recognition. Magnetic resonance imaging plays a critical role in diagnosing metronidazole-induced encephalopathy, with characteristic imaging findings frequently observed in the dentate nuclei and corpus callosum.
