 ORBITS: There is asymmetric T2 hyperintensity within the left lacrimal gland. The optic nerves are symmetric and normal in size and signal intensity. There is no intraorbital mass or abnormal enhancement. There is no chiasmatic mass or parasellar abnormality. The extraocular muscles are unremarkable.BRAIN: 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. 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 skull, paranasal sinuses, and scalp soft tissues are unremarkable. There is minimal fluid within the left mastoid air cells.
Diffuse signal abnormality within the left lacrimal gland is nonspecific, but is likely treatment related. Otherwise, no evidence of an orbital mass or intracranial metastasis.
