垂体腺瘤质地与手术入路的探讨

目的 探讨大垂体腺瘤的手术入路。方法 分析了100例实性垂体腺瘤的临床表现、内分泌检查结果、MR检查T2信号特点及手术情况。结果 肿瘤质地软易切除者88例，其中生长激素腺瘤36例，泌乳腺激素腺瘤21例，无功能性腺瘤31例；MR检查T2像；高信号76例，等信号12例。肿瘤质地较韧者12例，其中泌乳激素腺瘤4例，无功能性腺瘤8例；MR检查T2像，高信号4例，等信号8例。结论 垂体腺瘤的质地与MR检查T2像信号强度、内分泌测定有关，可以指导大垂体腺瘤的手术入路选择。

The evaluation for consistency of pituitary adenoma and surgical approach

Objective To discuss the relationship between the hardness of pituitary adenomas with surgical approach.Methods 100 cases with solid tumors were studied. We have reviewed their clinical features, level of hormone, the signal intensity of MR and operative results. Results Among the 88 cases of adenomas with sofe texture, 36 cases of them were GH secreting adenomas, 21 cases were prolactinomas, 31 cases were nonfunctioning adenomas. 76 cases were with long T2 MR signal, 12 cases with equal T2 MR signal, The other 12 cases were with hard texture, which prolactionmas in 4 cases and nonfunctioning adenomas in 8. Long T2 MR signal were in 4 patients and equal T2 signal in 8. Conclusions There are relationship among the signal of T2 weight, level of hormone and texture of adenomas, which are very important for choice of surgical approach.
