Magnetic resonance imaging volumetric analysis for diabetic striatopathy with two episodes of hemichorea-hemiballism syndrome: A case report.

RATIONALE

Diabetic striatopathy (DS) is an uncommon movement disorder among diabetic patients characterized by clinical hemichorea-hemiballism with neuroimage change of the striatum. Here, we report a case of DS with relapsed hemichorea-hemiballism attacks even during euglycemic period, and the MRI changes by volumetric analysis.

PATIENT CONCERNS

A 69-year-old diabetic female suffered from a relapsed episode of hemichorea-hemiballism during her euglycemic period after the treatment of hyperglycemia.

DIAGNOSES

To investigate the serial MRI changes in a case with diabetic striatopathy who had clinical hemichorea-hemiballism syndrome.

INTERVENTIONS

Semi-quantitative volumetric analyses from T1 images of these brain MRIs were obtained during the disease course.

OUTCOMES

Besides, the negative finding of the first brain MRI during her first hospital admission, three afterward MRI examinations disclosed a waxing-and-waning mode of volume change from high-signal T1 images in left striatum. The clinical symptoms paralleled with the neuroimage changes in striatum. The MR signal volume changes were valuable for the clinical course of the hemichorea-hemiballism caused by diabetic striatopathy LESSONS:: Serial MR images for the diabetic striatopathy presented as a key pathognomonic relationship with the clinical hemichorea-hemiballism syndrome, assessed by our simplied volumetric analysis. Clinical involuntary movements may relapse and persist even with euglycemic condition as our case.
