 There is no evidence of intracranial hemorrhage or acute infarct. There is a focal dilatation of the left temporal horn with a possible associated intraventricular cyst only seen on the sagittal T1 sequence that measures approximately 7 x 18 mm. There is no associated enhancement. The ventricles and basal cisterns are otherwise normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull, paranasal sinuses, and scalp soft tissues are unremarkable. The midline structures and craniocervical junction are within normal limits.
Focal dilatation of the left temporal horn, possibly due to an intraventricular cyst such as an arachnoid or choroid plexus cyst, of unlikely clinical significance. Otherwise unremarkable MRI.
