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。方法：４３例均经手术及病理证实。其中２１～４０岁占８５％，均有高血压、低血钾史。仅部分病例有周期性软瘫及血和（或）尿醛固酮增多。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、增强效应差，常突出于肾上腺形成“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、实验室的检查。ＣＴ检查主要是确定肾上腺有否肿瘤，以及定位、定量的诊断。ＣＴ对肾上腺皮质腺瘤诊断可靠。薄层扫描、增强ＣＴ有利于低密度小腺瘤的显示，但尚有一定的限度。
Objective: To make a CT diagnosis of adrenocortical adenoma in this disease by CT examination of patients with primary aldosteronism. Methods: 43 cases were confirmed by surgery and pathology. Among them, 21 to 40 years old accounted for 85%, and all had hypertension and hypokalemia. Only some cases have periodic soft palate and increased blood and/or urine aldosterone. CT uses thin-layer scanning. Results: This group was a single sided adenoma. The small size (81% in diameter <2cm), low density, and poor reinforcing effect often highlight the adrenal gland’s “stem sign.” Conclusion: The diagnosis of primary aldosteronism is based on clinical manifestations and laboratory tests. CT examination is mainly to determine whether there is a tumor in the adrenal gland, as well as localized and quantitative diagnosis. CT diagnosis of adrenocortical adenoma is reliable. Thin-slice scanning and enhanced CT facilitate the display of low-density small adenomas, but there are still some limitations.
