Female, 56 years old, status post transsphenoidal hypophysectomy, postoperative evaluation. Evidence of recent transsphenoidal hypophysectomy is seen with surgical disruption of the sphenoid bone. Nonenhancing low and intermediate T1 signal material fills the sphenoid sinuses and the posterior nasal cavity compatible with postoperative fluid/blood product and/or packing.The previously seen large sellar and suprasellar cystic lesion has been significantly decompressed. A small residual area of presumed cystic material remains in the posterior aspect of the sella measuring 8 mm AP, 4 mm CC and 11 mm TV. The native pituitary gland appears to sit anterior to and above the residual cystic cavity. The pituitary stalk is at midline and enhances normally. Some residual deformity of the optic apparatus is seen compatible with chronic displacement and stretching from the prior cystic lesion.
Expected findings status post transsphenoidal surgery. The previously seen large cystic sellar and suprasellar lesion has been significantly reduced in size. A relatively small residual cystic cavity is evident in the posterior aspect of the sella with measurements as above.
