Hemichorea-hemiballismus (HCHB). Segment 1. Patient at presentation three days after symptom onset showing random and occasionally ballistic movements of the left upper and lower limbs. Segment 2. Post-treatment at nine months after symptom onset showing marked reduction in amplitude and intensity of the HCHB and residual mild choreoathetoid movements of the left upper limb.

Figure 1
Cranial magnetic resonance imaging of the patient at presentation. A non-enhancing hypointense focus (white arrow) on postcontrast T1 weighted imaging (A) is seen on the right subthalamic region and cerebral peduncle appearing hyperintense on axial (B), coronal (C) and sagittal (D) T2 weighted images, representing focal cerebritis. Also seen is an abscess formation in the left frontal region (white arrowhead) with a slightly hyperintense rim on noncontrast T1 weighted image (E) suggestive of tuberculoma. On postcontrast axial T1 weighted image (F), it appears rim-enhancing with a nodular area of enhancement along its medial wall possibly an “eccentric target sign”, with a hypointense core and surrounding moderate vasogenic edema on axial T2 weighted (G) and diffusion weighted (H) imaging. Considerations for this space-occupying lesion include a tuberculoma and cerebral toxoplasmosis.
