垂体腺瘤的IADSA诊断：附22例报告

IADSA Diagnosis of Pituitary Adenoma:22 Cases

对２２例手术病理证实的垂体腺瘤的ＩＡＤＳＡ（动脉内注射数字减影血管造影检查）资料进行了回顾性分析，８１．８２％的病例可见鞍内及鞍上占位征，若见到肿瘤染色及垂体包膜动脉显影则诊断较肯定。ＩＡＤＳＡ可排除鞍区其它病变；所见的肿瘤染色不均不能完全反映ＣＴ所见的瘤体密度不均，但ＣＴ见到强化者ＩＡＤＳＡ多可见肿瘤染色。

A retrospective analysisof 22 surgically and pathologicallyproved pituitary adenma cases wasmade,intrasellar and supersellar occu-pancy signs were depicted in 81.8%cases,rather determinate diagnosiscould be established if tumor stainand capsular arteries had also beenfound.with IADSA exa mination,other entitoes of sellar region couldbe excluded;heterogenous tumor stainwas not consistent to the uneven den-sity of pituitary adenomas on CTexaminatin,however,tumor stain co- uld be seen in most cases which en- hanced on CT scanning.
