Role of Cavernous Sinus Extension and MRI T2 Hypointensity in the Extent of Resection following Trans-Sphenoidal Surgery for Giant Pituitary Adenomas

Conclusions: Most cases of GPA can be adequately handled by trans-sphenoidal surgery. The presence of retrosellar, subfrontal, cavernous sinus extensions, and T2 hypointensity should alert the surgeon for likelihood of STR, postoperative residual tumor hemorrhage and need for second-stage endonasal or transcranial surgery. However, utilization of extended endoscopic route has allowed good debulking of tumors having subfrontal and parasellar extensions, which was not possible previously using traditional microscopic transsphenoidal surgery.
