Female, 19 years old, with elevated prolactin and irregular menses. The pituitary gland is well within normal limits for size. However, the sella is very shallow which puts the gland in contact with the optic apparatus and the inferior frontal lobes. There is essentially no suprasellar cistern. Rather than descending from the hypothalamus, the pituitary infundibulum takes a relatively horizontal course to its insertion point at the midline superior gland. In addition, it appears that the dorsum sellae projects into the posterior aspect of the gland at midline (see image 7 series 1400). The enhancement of the gland is very mildly heterogeneous, but no clear discrete lesions are identified. Enhancement of the infundibulum is normal.
Mildly heterogeneous pituitary enhancement is seen. White the possibility of a tiny focal lesion such as an adenoma cannot be excluded, this possibility is not highly suspected as there is no clear focal lesion identified. The pituitary gland is not enlarged. However, due to a very shallow sella, there is essentially no suprasellar cistern which allows the pituitary gland to contact the optic apparatus and the inferior frontal lobes. There may also be some impingement of the gland by the dorsum sellae. The infundibulum is forced to take a relatively horizontal course from the hypothalamus to its insertion point on the gland. It is unclear if these findings may be related to the patient's presenting symptoms.
