Male, 71 years old, with bitemporal hemianopsia, status post transsphenoidal hypophysectomy Findings are seen compatible with recent transsphenoidal hypophysectomy including inflammation and fluid within the sphenoid sinuses. Lobular T1 hyperintense material along the floor of the sella and adjacent sphenoid bone may represent blood product and/or surgical packing material. The previously seen large sellar and suprasellar mass has been significantly debulked. Suprasellar extension is much reduced compared to prior. Residual enhancing tumor measures up to 17 mm in the craniocaudal dimension, previously 29 mm; and up to 14 mm in the transverse dimension, previously 22 mm.The native pituitary gland is not well visualized. However, the pituitary stalk passes behind and to the right of the residual tumor which may indicate the location of the native pituitary parenchyma. The pre-chiasmatic right optic nerve and the chiasm itself appear to be chronically thinned.
Expected findings are seen status post transsphenoidal hypophysectomy. The previously seen large sellar and suprasellar mass has been significantly debulked with much reduced encroachment on the suprasellar cistern.
