5 day old ex-35 5/7 WGA female infant of a diabetic mother who we are seeing for episodic desaturations to the 50's as well as abnormal head CT. The images are degraded by motion artifact. There is trace subdural T1 hyperintensity along the posterior cerebral convexities. Prominent curvilinear susceptibility effect overlying the left medial cerebellar hemisphere. There is no evidence of acute infarct. There is paucity of myelination involving the peri-rolandic regions. The left lateral ventricle is slightly larger than the right lateral ventricle, which can represent a normal variant. The ventricles do not appear to be dilated otherwise. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. No evidence of acute infarct.2. Trace subdural hemorrhages posteriorly.3. Prominent curvilinear susceptibility effect overlying the left medial cerebellar hemisphere likely represents a prominent tentorial vein, which may represent an anatomic variant, although a vascular malformation cannot be entirely excluded and an MRA may be useful for further evaluation.4. Apparent delayed myelination.
