Hemichorea associated with cavernous angioma and a small errhysis: A case report and literature review

Jiqing Qiu et al. Medicine (Baltimore). 2018 Oct.

Abstract

Rationale: Chorea is a movement disorder characterized by randomly appearing involuntary movements of the face, neck, limbs, or trunk. Hemichorea is unilateral, involving one side of the body. Hemichorea is commonly caused by non-ketotic hyperglycemia and/or cerebrovascular injury to the contralateral basal ganglia.

Patient concerns: Here, we report the case of a patient diagnosed with hemichorea who had diabetes, cavernous angioma, and a small intracranial errhysis. Routine testing showed the patient's blood glucose level was slightly higher than the normal range.

Interventions: The errhysis was too small to be treated.

Diagnoses: Brain magnetic resonance imaging showed a cavernous angioma with a small errhysis in the right putamen.

Outcomes: Hemichorea was completely resolved after 4 months.

Lessons: If diabetes is well controlled and imaging indicates brain lesions suggestive of a recent stroke, a diagnosis of post-stroke hemichorea should be considered.

MRI at presentation showed a cavernous angioma and a small errhysis in the right putamen on axial T1-(A) weighted, T2-(B) weighted, and fluid-attenuation inversion recovery (FLAIR) (C) sequences. Diffusion-weighted imaging (DWI) showed no infarction (D).

Figure 2
MRI one month after initial presentation showed a cavernous angioma and infarction in the right basal ganglia region on axial T1-(A) weighted, T2-(B) weighted, FLAIR (C) sequences, and DWI (D).
