Preterm newborn, gestational age 28 weeks with parenchymal hemorrhage. There is predominantly T1 and T2 hyperintense with surrounding circumferential effect in the bilateral medial parietal and occipital lobes, perhaps with slight extra-axial extension. There also appears to be T1 hyperintensity in the overlying superior sagittal sinus. There are small scattered areas of susceptibility effect in the bilateral temporal lobes, ventricular system, posterior fossa, and right caudothalamic groove. The degree of myelination is within expected limits accounting for prematurity. There is no evidence of acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The posterior fossa structures appear unremarkable. The major cerebral artery flow voids are intact. The skull, paranasal sinuses, and scalp soft tissues are grossly intact. There is mild dilatation of the left lacrimal sac.
1. Subacute hemorrhages within the bilateral medial parietal and occipital lobes, perhaps with slight extra-axial extension. Apparent T1 hyperintensity in the overlying superior sagittal sinus may represent artifact versus thrombus and dedicated vascular imaging is recommended for further evaluation. 2. Small scattered areas of chronic hemorrhage in the bilateral temporal lobes, ventricular system, posterior fossa, and right caudothalamic groove.3. Small left lacrimal sac mucocele.
