69-year-old male status post transphenoidal hypophysectomy. Again seen are postsurgical changes related to transsphenoidal hypophysectomy with unchanged heterogeneous hyperdense material within the surgical bed in the suprasellar region measuring 2.0 cm x 1.7 cm x 2.4 cm (series 207, image 17; series 203, image 38). As before, the optic chiasm is not well delineated due to the adjacent heterogeneous collection. Bony defect along the posterior wall of the sphenoid sinus with low density likely representing additional postoperative material, also unchanged. Heterogeneous collection is also noted within the sphenoid sinuses presumably representing Merogel. Unchanged heterogeneous secretions within the nasal cavity, maxillary sinus and ethmoidal air cells with associated air-fluid levels within the maxillary sinuses, left greater than right.Gray-white matter differentiation is maintained. No acute intraparenchymal hemorrhage, mass effect or edema. The ventricles and sulci appropriate for patient's age with no midline shift. The mastoid air cells are clear. The imaged orbits are unremarkable.
1. No interval change in postsurgical findings related to transsphenoidal hypophysectomy with presumed blood products associated with postoperative material (Surgicel and gel-foam soaked in thrombin, Merogel) within the suprasellar region and sphenoid sinus. Postoperative bony defect along the posterior wall of the sphenoid sinus.2. Unchanged opacification of the nasal cavities, maxillary sinuses and ethmoidal air cells likely representing blood products.
