19-month-old with macrocephaly. History of prior IVH. MRI of the brain appears within normal limits for age. There is mild prominence of the bilateral frontal horns as well as the extra-axial CSF spaces along the bilateral frontal convexities, which is within normal limits for age. No findings to suggest hydrocephalus. No intracranial mass or mass effect is seen. Sulcation and myelination appear within normal limits for age. No focal structural lesions are appreciated. No evidence of acute infarct or hemorrhage. Midline structures including the corpus callosum are normal. Posterior fossa structures also appear within normal limits. Major flow-voids are preserved indicating vascular patency. Paranasal sinuses are partially pneumatized and demonstrate nonspecific opacification of the right maxillary sinus.
MRI of the brain is essentially unremarkable. There is mild prominence of the frontal horns of the lateral ventricles as well as of the extra-axial CSF spaces along the bilateral frontal convexities; these findings however are within normal limits for patient's age.
