MRI in posthemorrhagic ventricular dilation in a patient with a grade III IVH

The first MRI, coronal (A) and sagittal (B) T2-weighted sequence, is performed on day 21 of life in a patient born at a gestational age of 31 weeks. A large blood clot is seen in the dilated left ventricle (arrows). At term-equivalent age, coronal (C) and sagittal (D) views show that the clot has mostly resolved and only the occipital horn is still enlarged (D, thick arrow). There is also an enlarged extracerebral space.
