 3-D T1 images are slightly degraded by artifact.There is an elongated appearance of the head shape in the AP dimension, which relates to scaphocephaly from premature fusion of the sagittal suture. Mild prominence of the ventricles and subarachnoid space anteriorly bilaterally. Questioned mild delay of myelination in the frontal and temporal lobes, provided corrected age.Stable cavum septum pellucidum. Basal cisterns are patent. No midline shift or mass effect. There is no diffusion abnormality, acute hemorrhage, or abnormal enhancement. 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.
No focal abnormality. Mild prominence of anterior subarachnoid spaces and ventricles likely relates to benign external hydrocephalus of infancy, which usually resolves by two years of age. Follow-up imaging may be obtained as clinically indicated.
