Spells of peripheral loss of vision bilaterally, but normal EEG. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. In particular, the hippocampi are intact and there is no evidence of heterotopia. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift. However, the cerebellar tonsils extend up to 5 mm inferior to the foramen magnum. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is mild mucosal thickening in the right maxillary sinus.
