Metabolic causes have been documented earlier, note worthy of that being Diabetes. Choreoathetosis has been reported earlier in diabetes mostly in an elderly female, diagnosed most often by Brain MRI. We report a case of hemichoreoathetosis in a male diabetic, whose involuntary movement completely resolved with glycemic control and diagnosis was easily confirmed with just a Brain CT. https://acta.tums.ac.ir/index.php/acta/article/view/3953 https://acta.tums.ac.ir/index.php/acta/article/download/3953/3928
