Pituitary microadenoma, yearly follow up. BRAIN: There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma appears unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable. There is a right maxillary sinus retention cyst. PITUITARY: There is redemonstration of mild prominence of the pituitary gland measuring 11 x 9 mm in the transverse by craniocaudal dimensions (image 8, series 801 and image 6, series 1101), which is unchanged in size. There is a symmetric convex superior margin of the gland. There is uniform enhancement of the pituitary gland without signal abnormality to suggest a discrete mass. There is minimal leftward deviation of the pituitary stalk, but it is normal in caliber, signal intensity, and enhancement. The suprasellar cistern, optic chiasm, hypothalamus, and cavernous sinuses are unremarkable.
No significant interval change in mild pituitary prominence. No discrete pituitary mass is identified.
