Neurology Case: Tooth-like nuclear signs of subacute cerebellum cogens: mitanetin neurotoxicity

A 79-year-old woman developed infectious aortic inflammation after repairing an aortic aneurysmAfter January, the patient satout for vertigo, sound disorders and gait instability, and sexual aggravation developed into inability to stand, pain-feeling abnormalities and disorientationThe check-up suggests poor dialectics, rotational movement disorders, motor disorders and severe cerebellum co-encephalopathyPatients have extensive laboratory tests, including autoimmune and secondary tumor-related contentThe obvious toothcore high signals on T2WI and FLAIR are ignored (figure)Fifteen days after the deactivation of methazole, cerebellum syndrome and toothy nuclear abnormality signals improvedIn addition to encephalopathy and multiple neuropathy, mitanezole can also cause subacute cerebellum coenophactic disorders through selective lysing and the toothy nucleusUnderstanding this imaging feature can identify reversible medical complications and avoid unnecessary examination(Figure: A: FLAIR visible two-sided tooth check after taking mitanepyridine in January, high signal; B: 15 days after the deactivation of mitanepyrium, the tooth-shaped nuclear signal returns to normal)
