摘　　要：目的 对肾上腺罕、少见肿瘤的CT表现进行探讨。方法 回顾性分析经手术病理证实的17例肾上腺罕、少见肿瘤(节细胞神经瘤4例,神经鞘瘤5例,畸胎瘤3例,淋巴瘤2例,神经鞘瘤合并节细胞神经瘤、血管肉瘤、骨外尤文肉瘤各1例)的CT影像资料,并复习文献。结果 17例肾上腺罕、少见肿瘤的男女比例为12∶5,年龄7~70岁。节细胞神经瘤多呈水滴形,较大可呈钻缝样生长,即“尖角征”,增强动脉期无明显强化,延迟期可无强化或轻度强化;神经鞘瘤具有完整的纤维包膜,常呈渐进性不均匀强化;畸胎瘤可含脂肪成分及钙化等;血管肉瘤中心常见大面积坏死,增强与血管瘤强化方式相似;淋巴瘤双侧好发,体积较大则密度欠均;骨外尤文肉瘤多为密度欠均的较大肿块,易囊变、坏死,强化不均匀。结论 肾上腺罕、少见肿瘤在CT上具有一定影像特点,可为临床对肾上腺疾病的诊断提供帮助。Objective To investigate the CT findings of rare and uncommon tumors of the adrenal gland.Methods CT imaging data of 17 patients with rare and uncommon adrenal tumors confirmed by surgery and pathology were retrospec⁃tively analyzed(4 cases of ganglioneuroma,5 cases of schwannoma,3 cases of teratoma,2 cases of lymphoma,and 1 each of schwannoma with ganglioneuroma,angiosarcoma,and extraosseous Ewing sarcoma),and the literature was reviewed.Re⁃sults The male⁃to⁃female ratio of the 17 cases with rare and uncommon adrenal tumors was 12:5,and the age distribution was 7~70 years.Ganglioneuromas were mostly water⁃drip⁃shaped,and larger ones may grow in a slit⁃like pattern,i.e.,the"apical sign",with no significant enhancement in the enhanced arterial phase and no or mild enhancement in the delayed phase;schwannoma had an intact fibrous envelope and often showed progressive inhomogeneous enhancement;teratoma may contain fatty components and calcification,etc.;angiosarcoma commonly had large necrosis in the center,and enhance⁃ment was similar to that of hemangioma;lymphoma is bilaterally prevalent and was less uniform in density if larger;extrao⁃sseous Ewing sarcoma was mostly a large lump of uneven density,prone to cystic degeneration and necrosis,and uneven en⁃hancement.Conclusion Rare and uncommon tumors of the adrenal gland have certain imaging features on CT and may contribute to the clinical diagnosis of adrenal disease.
