 This exam is mildly degraded by motion artifact.ORBITS: There is thickening as well as abnormal T2 hyperintensity and enhancement of the right nasolacrimal sac and nasolacrimal duct. There is also swelling and abnormal T2 hyperintensity of the right lower lid. The optic nerves are symmetric and normal in size and signal intensity. There is no intraorbital mass. There is no chiasmatic mass or parasellar abnormality. The extraocular muscles are unremarkable.PITUITARY: There is a normal pituitary height for age. The infundibulum is midline. There is no evidence for pituitary or suprasellar mass. The optic chiasm, cavernous sinuses and intracranial portions of the optic nerves are normal in appearance.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 and scalp soft tissues are unremarkable. The midline structures and craniocervical junction are within normal limits. There is fluid within the left sphenoid sinus and right mastoid air cells.
1.RIght nasolacrimal sac and duct enlargement, edema, and enhancement with associated edema of the right lower lid. The nasolacrimal sac size is grossly unchanged compared with the CT dated 4/30/2014 although the etiology is uncertain. 2.Normal pituitary MRI. 3.Normal brain MRI. 4.Minimal nonspecific fluid within the left sphenoid sinus and right mastoid air cells.
