(A) magnetic resonance imaging (MRI) at admission. A few ischaemic foci are already observed as FLAIR-hyperintensities in both cerebral hemispheres. (B) MRI after 1 week (FLAIR). More extensive, confluent, bilateral infarcts. The biggest one, cortical–subcortical, involves the left frontal lobe. (C) MRI 1 month after disease onset (FLAIR). Hydrocephalus with CSF transudation, post-ischaemic lesion in the left frontal lobe with laminar necrosis of the overlying cortex. (D) MRI after 7 months (FLAIR). Progression of hydrocephalus, scarring of the right frontal lobe as well, subdural haematoma over the left cerebral hemisphere. (E) MRI after >6 years (FLAIR). Smaller degree of ventricular dilatation after ventriculoperitoneal shunt placement. Abnormal, hyperintense white matter with lacunar post-infarct foci. Cortical–subcortical scars in both frontal lobes (L > P). Chronic bilateral subdural haematomas. (F) CT after >12 years. Overdrainage with slit-like lateral ventricles. Scar in the left frontal lobe. Thickened calvarial vault associated with ventricular shunting for hydrocephalus at a young age was observed 6 years earlier (G).
