Pituitary lesion with vision changes that developed during pregnancy. The pituitary gland has decreased in size, measuring up to 12 mm in craniocaudal dimension, previously 22 mm. In addition, there is now only a residual streaky area of non-enhancement in the mid portion of the gland. The pituitary gland nearly abuts, but no longer exerts mass effect upon the optic apparatus. The pituitary infundibulum and posterior pituitary bright spot are intact. There is mid mucosal thickening in the right maxillary sinus. The imaged portions of the brain are unremarkable.
Interval decrease in size of the pituitary gland, with what may represent the sequela of necrosis, such as Sheehan syndrome, versus apoplexy.
