Female 16 years old Reason: please evaluate for structural abnormality History: possible seizure There is prominence of the lateral ventricles, left greater than right, similar to prior exam, with colpocephalic configuration. The third ventricle and fourth ventricle as well as the basal cisterns are also enlarged, similar to prior exam. There is dysgenesis of the corpus callosum. There are a few nonspecific small FLAIR signal abnormalities in the periventricular white matter. There is a 3 mm probable lipoma in the cerebellomedullary cistern on the left. Possible inferior vermian hypoplasia is noted.There is no evidence of intracranial hemorrhage, mass or edema. No abnormal extra-axial fluid collection is identified. There is no midline shift or mass effect. There is no diffusion abnormality to suggest acute infarction. Normal flow-voids are demonstrated in the major intracranial vascular structures.There is mucosal thickening in the maxillary sinuses, the anterior ethmoids, sphenoid sinus and the frontal sinuses.
