[Hemichorea-hemiballism associated with nonketotic XXXX and presenting with unilateral hyperintensity of the putamen on MRI T1-weighted images--a case report].

A 74-year-old @entity1 was admitted to our hospital with abrupt onset of @entity2358 in the left arm and leg. On admission, the blood @entity413 level was 296 mg/dl, glycosylated hemoglobin Alc was 17.0%, and the serum osmolality was 296 mOsm/l. Urinalysis was negative for @entity6178 bodies, but was strongly positive for @entity413 . After normalization of the blood @entity413 level, ballistic @entity717 , but @entity4790 of the left arm and leg continued for 10 months. Brain CT showed a slight high density of the right putamen, which disappeared on 37th day after the onset. MRI showed high intensity on T1-weighted images and low intensity on T2-weighted images in the right putamen, which disappeared 10 months after the onset. SPECT on the 21th day after the onset showed hyperperfusion in the right putamen. 4 months later, the blood flow slightly reduced in the right putamen. The abnormality in the right putamen was considered to be the cause of his @entity2358 . High intensity in the putamen on T1-weighted MR images in the present case are presumed to have developed following mild @entity63 and the reversible deposition of @entity460 or other material which occurred in association with nonketotic @entity4854 .
