Mittal %J Iranian Journal of Radiology %D 2011 %I Tehran University of Medical Sciences %X Hemichorea-hemiballism (HCHB) syndrome, which is most commonly related to non-ketotic"nhyperglycemia, is a rare type of chorea. Here, we present an unusual case of HCHB syndrome who"nwas not a known case of diabetes. This case highlights the importance of recognising underlying"nnon-ketotic hyperglycemia, as control of hyperglycemia is helpful in the quick relief of symptoms. %K Keywords: Hemichorea %K Hemiballism %K MRI %K Ischemia %K Diabetes %U http://journals.tums.ac.ir/PdfMed.aspx?pdf_med=/upload_files/pdf/18535.pdf&manuscript_id=18535
