Metronidazole neurotoxicity: Sequential neuroaxis involvement
Park, Kyung-Il; Chung, Jae-Myun & Kim, Ji-Young
Abstract
Neurological manifestation of metronidazole toxicity include neuropathy and encephalopathy. We report a 67-year-old man with progressive painful paresthesias involving all the four limbs of 3 weeks' duration before admission. He had been treated with metronidazole and cephalosporin for 10 weeks for a hepatic abscess. Five weeks after the symptom onset, he complained of dysarthria and limb ataxia. Magnetic resonance imaging revealed signal abnormalities in the splenium of the corpus callosum and bilateral dentate nuclei. A few hours after brain imaging, the patient exhibited excessive diaphoresis and fluctuation in blood pressure, which resolved within several hours after discontinuation of metronidazole. Whereas his speech returned to near normal within approximately 1 week, a burning sensation was not completely relieved, even 6 months after discharge.
