Reason: history of pituitary enlargement and stalk thickening on outside imaging, hyperprolactinemia History: hyperprolactinemia. Please note that dynamic contrast-enhanced sequences were not obtained.The pituitary is slightly prominent measuring 9 mm with a convex superior margin as well as prominence of the inferior infundibulum. No identifiable microadenoma or macroadenoma. Small linear foci of low signal in the posterior pituitary favored to represent a tiny pars intermedius cyst/remnant.There is otherwise no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma appears unremarkable. 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, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1.No convincing evidence of a pituitary microadenoma or macroadenoma. Please note dynamic postcontrast sequences were not obtained with slightly limits sensitivity for pituitary microadenomas. If clinically indicated, patient may return for this additional sequence at no additional charge. 2.Mild diffuse prominence of the pituitary and lower aspect of the infundibulum is nonspecific but within normal limits for patient's age.
