53 years, Female, acute delirium and bipolar episode. No restricted diffusion to suggest acute ischemia. There is no intracranial hemorrhage, intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Few foci of T2/FLAIR hyperintensity are seen in the periventricular white matter, which are nonspecific, but probably secondary to chronic small vessel ischemic changes. Brain parenchyma is otherwise unremarkable for age.No abnormal parenchymal or meningeal enhancement. Major flow-voids are preserved. A left posterior frontal deep venous anomaly is incidentally noted.Sella and orbits are grossly within normal limits. A mucous retention cyst is present within the right maxillary sinus. The paranasal sinuses and mastoid air cells are otherwise clear. Bone marrow signal and extracranial soft tissues are within normal limits.
No evidence of intracranial hemorrhage, mass, or acute infarction.
