Male, 41 days old, ex 28 weeker with history of presumed meningitis, now with poor head growth. Hemosiderin staining is evident along the germinal matrices bilaterally. Hemosiderin staining is also evident within the occipital horn of the left lateral ventricle. A small focus of susceptibility effect is demonstrated in the left cerebellar hemisphere.The corpus callosum is fully formed and intact. The pituitary region is within normal limits. The brainstem, cerebellar vermis and cerebellar hemispheres are normally formed and unremarkable.No restricted diffusion is seen. The ventricular margins are smooth and symmetric. Ventricular size is within normal limits. No areas of parenchymal signal abnormality, edema or mass effect are observed.  The degree of cerebral gyration is appropriate for the corrected gestational age. White matter myelination is slightly delayed for the corrected gestational age.
1.Sequelae of mild bilateral germinal matrix hemorrhages are seen. In addition, there is evidence of hemosiderin staining within the left lateral ventricle which would imply some degree of intraventricular hemorrhagic extension. Ventricular size, however, remains within normal limits.2.A small focus of susceptibility effect within the left cerebellum is nonspecific. This could be artifactual or could represent a small area of chronic microscopic hemorrhage.3.No evidence of any large acute or chronic ischemic injury.4.The degree of gyral development is appropriate for the corrected gestational age. White matter myelination is slightly delayed for corrected gestational age.
