Demyelinating disease: fatigue, vertigo. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There are mild secretions in the left ethmoid sinuses and a small retention cyst in the left maxillary sinus. The orbits, skull, mastoid air cells, and scalp soft tissues are grossly unremarkable. There is nonspecific prominence of the adenoids.
1. No evidence of intracranial demyelinating lesions or mass. 2. Nonspecific prominence of the adenoids, which may be attributable to lymphoid hyperplasia. Nevertheless, endoscopic examination may be useful.
