케톤성 고혈당과 관련된 단무도증으로 처음 진단된 당뇨병 1예

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 striatalhyperintensities (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.
