由于第3与第4代计算机断层扫描的广泛应用,虽然有的病例既无高血压又无提示库兴氏综合征阳性发现,并未曾怀疑有功能肾上腺瘤,但经CT检查偶然发现肿瘤。临床上这类病例并不罕见。据的文献报告尸检发现肾上腺皮质结节的发生率为1—3%。但不管患者有无高血压,应排除嗜铬细胞瘤。在没有其他临床发现的患者中有人认为不必要检查,有人主张查血或尿中皮质类固醇。病变大于5cm Due to the widespread use of 3rd and 4th generation computed tomography scans, although there were cases of hypertension with no positive Cushing’s syndrome findings and no functional adrenal tumors were suspected, tumors were found accidentally by CT examination.

In some patients without other clinical findings, it was considered unnecessary and some people advocated blood or urinary corticosteroids. Lesion greater than 5cm
