Imaging plays an important role in evaluating fortuitously discovered adrenal masses. These unanticipated masses (incidentalomas) are usually discovered at CT examinations. Although most incidentally discovered adrenal tumors are non-hyperfunctioning adenomas, they must be distinguished from primary or secondary malignant lesions. Recent studies have established that both unenhanced CT scans and chemical shift MR imaging can accurately differentiate benign adenomas from nonadenomatous masses by features that reflect the large amount of lipid found in most adenomas and absent in most nonadenomas. We review here the current imaging issues concerning adrenal incidentalomas including diagnostic approaches and management.
影像学在评估偶然发现的肾上腺肿块中起着重要作用。这些意外发现的肿块（偶发瘤）通常在CT检查时被发现。尽管大多数偶然发现的肾上腺肿瘤是非功能性腺瘤，但必须将它们与原发性或继发性恶性病变区分开来。最近的研究表明，非增强CT扫描和化学位移磁共振成像都可以通过反映大多数腺瘤中存在而大多数非腺瘤中不存在的大量脂质的特征，准确地将良性腺瘤与非腺瘤性肿块区分开来。我们在此回顾当前有关肾上腺偶发瘤的影像学问题，包括诊断方法和处理。
