摘　　要：目的：通过对原发性醛固酮增多症患者的ＣＴ检查，着重提出本病肾上腺皮质腺瘤的ＣＴ诊断。材料和方法：本文４３例均经手术及病理证实，男１１例，女３２例。年龄２１～５６岁，其中２１～４０岁占８５％。均有高血压病史及低血钾。ＣＴ使用薄层扫描。结果：本组均为一侧单发腺瘤，体积较小（直径＜２ｃｍ占８１％）密度低而且均匀。增强效果差，且突出于肾上腺形成“柄征”。结论：对原发性醛固酮增多症的诊断，主要依据临床表现，实验室检查材料。ＣＴ检查主要是要确定肾上腺是否有肿瘤，以及定位定量诊断。ＣＴ对肾上腺皮质腺瘤诊断可靠，醛固酮腺瘤有其ＣＴ影像特点，故ＣＴ检查有助于临床不典型病例的诊断。薄层扫描，增强ＣＴ有利于小腺瘤的显示。PURPOSE:Using CT to establish the diagnosis of corticoadrenal adenoma by examining patients with primary aldersteronism.MATERIALS AND METHODS:The 43 patients discussed in this article all experienced surgical operations and pathological confirmations. 11 males, 32 females. aged from 21 to 56. 85 percent of the patients aged from 21 to 40. All the patients are hypertensives with hypopotassemia. Applying thin slice scanning to all patients when examined with CT. RESULTS: All patients have only one adenoma on one side of the adrenals. The adenomas are small and 81 percent of their diameters are less than 2cm, they presented low density and poor contrast effect projetcting from the adrenal and forming “handle sing”. CONCLUSIONS: The indications of primary aldersteronism are its clinical findings and laboratory results. The examination of CT. is to detemine the existence of tumors on adrenal,the position and the size of them. The CT. diagnosis of aldersteronoma is reliable, because the aldersteronoma has typical signs on CT.image. CT.can help determine patients with atypical clinical diagnosis. Thin slice CT. scanning and Contrast CT.scanning will help dectect even small tumors.
