Hyperglycaemia with hemichorea (HGHC) is an unusual clinical entity that can be associated with corpus striatum hyperintensity on T1-weighted (T1W) magnetic resonance imaging (MRI) sequences. We report the utility of the susceptibility weighted image (SWI) sequence and the filtered phase SWI sequence in the imaging assessment of HGHC. 1. Case Report A 54-year-old man presented to the emergency department with a 5-day history of right-sided HemiChorea on a back-ground of type II diabetes and hypertension. There was no personal or family history of movement disorders and no history of neuroleptic drug use. At presentation, serum blood glucose level was 36.2mmol/L with an HbA1c of 16%. There was no ketonuria. The hemichorea resolved with optimal blood glucose control. Initial nonenhanced CT (NECT) head demonstrate
