Ultrasound and MRI of posthemorrhagic hydrocephalus in a patient with periventricular hemorrhagic infarction
Follow-up ultrasound and MRI performed six months after initial imaging demonstrated periventricular hemorrhagic infarction (grade IV IVH) in a preterm infant. Coronal (A) and sagittal (B) ultrasound images demonstrate marked hydrocephalus (arrow). In addition, T2-weighted (C) and FLAIR (D) MRI demonstrate massively enlarged right lateral ventricle (short arrow) with near-complete absence of the right hemispheric white matter and relative sparing of right frontal lobe white matter (dashed arrow).
