目的　探讨肾上腺转移瘤的CT特征及CT在肾上腺转移瘤诊断中的应用价值。方法　对 4 2例病人作CT扫描 ,其中 37例作增强扫描。结果　单侧肾上腺肿块 2 8例 (6 6 7% ) ,双侧 2 2例 (33 3% )。肿块直径大小范围 1 5cm～ 12cm ,分别呈圆形、卵圆形和分叶状不规则形。密度为实性、囊性或囊实性 ,增强后实性肿块及囊壁有强化。结论　CT是发现肾上腺肿瘤可靠、有效的检查方法。肾上腺转移瘤的诊断是综合性的 ,包括原发癌史、恶性征等。肾上腺肿块的恶性征为肿块直径 >5cm ,常呈分叶或不规则外形 ,密度不均。 Objective To investigate the CT features of adrenal metastases and the value of CT in the diagnosis of adrenal metastases. Methods CT scans were performed on 42 patients, of which 37 were used for enhanced scans. Results The unilateral adrenal mass was 28 cases (66.7%), and the bilateral side was 22 cases (33. 3%). The diameter of the tumor ranged from 15 cm to 12 cm, which were round, oval and lobulated irregularly. Density is solid, cystic or cystic solid, and the solid mass and cyst wall are strengthened after enhancement. Conclusion CT is a reliable and effective method for detecting adrenal tumors. The diagnosis of adrenal metastases is comprehensive, including the history of primary cancer, malignant signs, and so on. The malignant sign of the adrenal mass is a mass with a diameter of >5cm. It often presents a leafy or irregular shape with uneven density.
