 There is a 2 x 7 x 3 mm mildly T2 hyperintense, T1 hypointense, slightly heterogenous lesion within the posterior aspect of the pituitary gland. The posterior pituitary bright spot is absent. The infundibulum is slightly deviated to the left. The pituitary and sella are small for age with the pituitary measuring only 3 mm in height. There is no evidence for a suprasellar mass. The optic chiasm, cavernous sinuses and intracranial portions of the optic nerves are normal in appearance.There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is moderate global volume loss. There are no areas of abnormal parenchymal signal. 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. There is fluid and mucosal thickening throughout the paranasal sinuses and mastoid air cells.
1.Posterior pituitary lesion that may represent a congenital cyst or a microadenoma and could be further characterized with a contrast exam when able to tolerate.2.Small pituitary gland and sella as well as global cerebral volume loss.3.Absent posterior pituitary bright spot.4.Paranasal sinus opacification and non-specific mastoid air cell fluid. Please correlate clinically.
