Case ReportsCase report of hyperglycemic nonketotic chorea with rapid radiological resolution.
Hemichorea is a rare manifestation of nonketotic hyperglycemia that usually affects elderly Asian women with poor glycemic control. Non-contrast computerized Tomography and T1- weighted Magnetic Resonance Imaging shows characteristic hyperintense basal ganglia lesions. ⋯ This is a rare manifestation of diabetes in Sri lanka and diagnosing this rare entity will direct clinicians to achieve optimum glycemic control as the treatment which will lead to rapid clinical response without any other medications. In this case report we high light that with the clinical improvement, repeating a CT scan even after a very short period like 2 weeks will show rapid radiological resolution. This repeat imaging can also be useful to confirm the diagnosis, which will minimize unnecessary investigations and treatments. Further cases of hyperglycemic nonketotic chorea with brain imaging performed within short intervals is needed to evaluate the nature of rapid radiological changes, which will be useful to understand the pathology of this condition.
