Female, 25 years old, with bilateral nonspontaneous nipple discharge and recent elevated prolactin levels. Assess for pituitary lesion. The pituitary gland is somewhat asymmetric in that the right aspect of the gland is larger than the left. However, without the benefit of contrast enhancement, no focal glandular lesions are seen. The pituitary infundibulum is at midline. The suprasellar cistern, visualized optic pathway and cavernous sinuses are within normal limits.
Asymmetry of the pituitary gland is seen with the right side being somewhat larger than the left. The significance of this finding is uncertain, and this could in fact represent normal anatomic variation. Within the limitations of a noncontrast examination, no focal lesions are identified.
