From: Cortical ischaemic patterns in term partial-prolonged hypoxic-ischaemic injury—the inter-arterial watershed demonstrated through atrophy, ulegyria and signal change on delayed MRI scans in children with cerebral palsy

a–e Peri-Sylvian and posterior watershed injury in a 4-year-8-month boy. a, b Axial FLAIR images at two different levels which not only demonstrate the peri-Sylvian and posterior watershed distribution of the atrophy (arrows) but also demonstrate the underlying white matter signal abnormality up to the ventricular edge, with white matter volume loss. c Coronal T2-weighted imaging confirms the atrophy and signal abnormality of the posterior watershed in another plane (arrows) and demonstrates relative sparing of the occipital lobes just above the tentorium. d Sagittal T1-weighted image demonstrates the peri-Sylvian distribution of atrophy (arrow). e Sagittal midline T1 shows the marked volume loss of the posterior body, isthmus, and splenium of the corpus callosum (arrow) corresponding to cortical and white matter volume loss in the posterior watershed
