 There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are no areas of abnormal parenchymal signal. There is no abnormal intracranial enhancement. There is a 6 mm presumed pineal cyst. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The midline structures and craniocervical junction are within normal limits without evidence of abnormal CSF flow dynamics at the level of the foramen magnum. The major cerebral flow voids are intact. The skull, paranasal sinuses, and scalp soft tissues are unremarkable. There is minimal fluid within the left mastoid air cells.
