Ipsilateral putamen hyperintensity on T1-weighted MRI in non-ketotic hyperglycemia with hemiballism-hemichorea: a case report.
Movement disorders are often caused by lesions in the contralateral basal ganglia. This report presents an elderly woman with hemiballism-hemichorea induced by non-ketotic hyperglycemia, whose brain CT revealed a hyperdense lesion over the ipsilateral putamen. Concomitantly, MR image revealed a putaminal hyperintensity on T1-weighted image and hypointensity on T2-weighted image. A follow-up brain CT 4months after remission of the hyperkinesia revealed that the abnormal intensity had been completely resolved.
