Video documentation of the patient’s abnormal movements upon consult at our institution. Chorea was predominantly seen on the right leg more than the right arm. Minimal choreiform movements were also appreciated on the left upper limb. Parakinesia and spooning sign, seen as finger hyperextension interrupted by choreiform movements, were also noted on the right upper limb.

[A-D] Plain cranial CT demonstrating beginning communicating hydrocephalus as evidenced by the dilated temporal horns (green arrowhead, A) and third ventricle (green arrowhead, C). Also shown is diffuse cerebral edema as evidenced by the effaced sulci-gyri interface (thick orange arrows, D). [E-H] Contrast-enhanced sequences showing basal enhancements (red arrowheads, E) and non-enhancing hypodensities involving the right caudate head (thin yellow arrow, F), right lentiform nucleus, & right internal capsule (thin blue arrow, G). Also seen are undue leptomeningeal enhancements.
