Cystic pituitary adenoma

Case contributed by Yari Anahi Ramos
Diagnosis possible


Galactorrhea, and elevated prolactin.

Patient Data

Age: 20 years
Gender: Female

The pituitary fossa is enlarged and contains a cystic lesion with a fluid-fluid level seen on T2 sagittal images. The infundibulum is displaced to the left. Enhancing tissue surrounds the cyst without nodularity or masses.

Case Discussion

The presence of fluid-fluid level in a cystic pituitary lesion favors a cystic pituitary adenoma over a Rathke cleft cyst 1,2.

No histology is available at this time.

Elevated prolactin may be due to secretion or stalk effect.
