摘　　要：本文报告14例垂体微小腺瘤的蝶鞍平片、多轨迹体层照片及 CT 扫描的对比分析,充分显示多轨迹体层照片对诊断垂体微小腺瘤准确率高、检查方便、费用低廉的优点。临床上疑有垂体微小腺瘤而蝶鞍平片及 CT 扫描难以确诊或已基本确诊但尚需了解蝶鞍骨质改变、蝶窦气化程度及肿瘤侵犯等情况时,应作体层照片检查。作者认为在体层照片中鞍底倾斜或凹陷即使不超过2mm,但有鞍底骨皮质的侵蚀或破坏者仍应考虑有垂体微小腺瘤存在。This report analyzes 14 patients with pituitary microadenomas diagno- sed bt plain film,polytomography and C T scanning.In comparison, the polytomography is more accurate in demonstrating a pituitary microa- denoma,more convenient in examination and costs less.If a patient is sus- pected clinically to have intrasellar pituitary microadenoma but without an abnormal plain film and C T findings,or if a diagnosis is made but a further investigation is needed of the tiny changes in sella sphinoid,sinus gasification and bony invasion by the tumor,it is better to take a polyto- mography.Even the sloping and depression does not exceed 2 mm.in poly- tomography,so long as there is an erosion of the floor of the sella turcica, intrasellar pituitary microadenoma should be considered.
