Magnetic resonance imaging (MRI) of posthemorrhagic hydrocephalus in a patient with grade III IVH

In a follow-up MRI obtained 1 year following initial presentation, axial FLAIR images (A, B, C, D) demonstrate marked bilateral hydrocephalus with colpocephalic features, hypoplasia/atrophy of the cerebellum (arrowhead), and dysmorphia of the pons (short arrow). Coronal CISS image (E) demonstrates disproportionate dilation of the atrium and occipital horn of the lateral ventricle (dashed arrow), reflecting the colpocephalic features.
