Former 30 3/7 week premature infant girl with history of cardiac arrests. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is deficient white matter myelination, which is mainly limited to the brainstem and portions of the cerebellum. In particular, there is no appreciable T1 hyperintensity of the posterior limbs of the internal capsules of peri-Rolandic regions. There is mild patchy symmetric T1 hyperintensity of the bilateral anterior thalami and globi pallidi. The ventricles and basal cisterns are normal in size and configuration. 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.
Paucity of white matter myelination, which may be commensurate with corrected age for prematurity. Otherwise, no evidence of mass lesions, acute cerebral infarction, intracranial hemorrhage, hydrocephalus, or encephalomalacia.
