A Case of Type 2 Diabetes Mellitus Initially Presented as Monochorea Associated with Ketotic Hyperglycemia / 임상당뇨병

ABSTRACT

Monoballismus-monochorea is abnormal neurologic sign characterized by continuous, involuntary and irregular movement involving one extremity. Hyperglycemic ballism-chorea is predominantly observed in older type 2 diabetic patients and non-ketotic hyperglycemia, and is associated with contralateral striatal hyperintensities (i.e., putamen and caudate) on both brain CT and MRI. Movement disorders as the initial symptoms of diabetes mellitus are rare, especially in ketotic hyperglycemia. Here, we report one of these rare manifestations of transient monoballismus with during an episode of ketotic hyperglycemia without contralateral striatal abnormal findings on brain MRI in newly diagnosed diabetes mellitus.
