case_images: Cortical laminar necrosis (CLN) on brain MRI. (A) Acute left cerebellar stroke (*), which is the putative explanation why the patient fell and stayed down. Other brain lesions, which spared the white matter, were not congruent with arterial territories. Willis circle, brain and cervical arteries were normal (not shown). (B and C) Diffuse CLN spread over the right hemisphere and minimally diffusing over the left paramedial cortex (<). (D) Cranial computed tomography showing left subgaleal traumatic hematoma (*) and right contrecoup subdural (>) and subarachnoid hemorrhage (<). (E) Increased T1w signal in deep grey matter structures (>), typically associated with chronic hepatic encephalopathy. Axial brain MRI with DWI (A-C) and T1-weighted (E) sequences.

case_images: Diffusion-weighted imaging (DWI) revealed acute left cerebellar infarction and diffuse cortical lesions, mostly involving the right temporo-fronto-parietal cortex including the caudate nucleus (Fig. 1).
