 Images are partially degraded by motion artifact. There is prominence of the ventricles as well as the subarachnoid spaces around the frontal and temporal lobes, consistent with benign expansion of the subarachnoid spaces in infancy. Additionally, the insulae are somewhat exposed for age, which may suggest underdevelopment of the opercular gyri, although this may also be related to BESS. The basal cisterns remain patent. There is no midline shift or mass effect. Myelination appears appropriate for age. There are no areas of abnormal signal or diffusion abnormality. No extra-axial fluid collection is identified. Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits.
1.No definite parenchymal lesion or structural abnormality is identified.2.Findings consistent with benign expansion of the subarachnoid space in infancy, which should resolve by age 2. If symptoms persist, follow-up imaging after 2 years of age may be considered.
