Fixed mass on the left temple. There is a well-defined heterogeneous predominantly high T2 and low T1 signal mass in the left temporal fossa that measures up to 25 mm. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is a probable chronic lacunar infarct in the left basal ganglia and mild scattered foci of T2 hyperintensity in the cerebral white matter. 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. The orbits are unremarkable. There is a subcentimeter left maxillary retention cyst.
A well-defined mass in the left temporal fossa that measures up to 25 mm may represent a lymphatic malformation or perhaps an inclusion cyst.
