累及海绵窦及鞍旁侵袭性垂体腺瘤的诊断及治疗

Diagnosis and treatment of involving cavernous and parasellar invasive pituitary adenomas

本文报告24例海绵窦内与鞍旁侵袭性垂体腺瘤。诊断中经CT与MRI等检查可显示肿瘤对海绵窦压迫或侵蚀的情况。本组将其分为四型,并依之分别采用经蝶窦、经额及经海绵窦入路显微手术。全部取得良好效果,无死亡。文内讨论了各种手术入路的指征。

The diagnostic key points of invasive pituitaryadenoma were studied in 24 cases. In case ofinvasive tumor, the parasellar dura matter and orthe cavernous sinus were infiltrated orinvaded. This should be differentiated from thatthe displacement of the sella structures caused bycompression rather than encroachment. The entitiesare more clearly demonstrated by MRI. The T_1weighted images will render excellent depictionsof topographic relationship. Tumors in our group weredivided into 4 types: (1) lateral extension of thetumor to the medial wall of the sinus; (2)localizedinvasion to the medial wall of the sinus, (3) diffuseinvasion of the whole sinus. (4) supra-diaphragm andparasellar extension with dura invasion.
