title: Hemichorea-hemiballism syndrome: A look through susceptibility weighted imaging.
abstract: Hemichorea-hemiballism syndrome (HCHB) is a relatively rare cause of unilateral chorea in diabetic patients and is due to non ketotoic hyperglycaemia. Characteristic magnetic resonance (MR) findings include T1 hyperintensity in the contralateral putamen without any significant signal alteration on other conventional MR sequences. We report susceptibility weighted imaging (SWI) findings in a case of HCHB syndrome.
