Ancillary Examinations in the Patient.. (A) From left to right, top to bottom: axial T2-weighted magnetic resonance imaging (MRI) scan shows a small line-shaped lesion on the left putamen/external capsule transition. Axial T2-weighted flair MRI scan shows left parietal, right frontobasal and right temporal gliosis. (B) Electromyogram of the right abductor pollicis brevis and abductor digiti minimi muscle shows irregular bursts of around 20 ms (horizontal axis time in seconds, vertical axis bursts in mV).

Brain magnetic resonance imaging is compatible with head trauma and showed left parietal, right frontobasal, and right temporal loss of brain tissue and gliosis and a small line-shaped lesion on the left putamen/external capsule transition (Figure 1A). Electromyography of the right arm and hand muscles showed brief irregular bursts with a duration of about 20 ms (Figure 1B).
