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。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: This paper was to assess CT characteristics of aldosterone-secreting adreno-cortical adenomas. Methods: 43 cases of pathologically confirmed adenoma were retrospectively reviewed. They were 11 males and 32 females. Age ranged from 21 to 56, and those aged from 21 to 40 accounted for 85% of the 43 patients. All patients had hypertention and hypokalemia, some had periodical muscle weakness and elevated level of blood and (or) urine aldosterone. Thin-slice CT scans were performed on all patients. Results: Unilateral solitary aldosteronomas were seen in all 43 patients. The tumors were small (81% of adenomas less than 2 cm in diameter), hypodense, poorly-enhanced as well as focally protruded (stalk-sing). Conclusions: Diagnosis of primary aldosteronism is established largely on the basis of clinical manifestation and labratory findings. CT is a reliable imaging modality that can play an important role in the identification and localization of aldosteronomas. Thin-slice plus enhanced CT scan may be of value in identifing tiny, hypodense aldosteronomas, althoush there are still some limitations.
