摘　　要：目的分析肾上腺原发性肿瘤的动态增强CT征象,提高对其诊断和鉴别诊断能力。方法回顾性分析经手术病理证实的118例肾上腺原发性肿瘤患者的临床和CT资料,并归纳总结其动态增强CT特征。结果 118例肾上腺原发性肿瘤,良性115例,恶性3例。双侧5例,单侧113例。肾上腺常见肿瘤大部具有典型CT征象,其中皮质腺瘤60例（50.8%）,密度较低且均匀,轻中度强化,对比剂廓清迅速;髓样脂肪瘤35例（29.7%）,以脂肪密度为主,强化不均匀,脂肪成分不强化;嗜铬细胞瘤11例（9.3%）,囊变、坏死多见,呈不均匀显著持续强化。肾上腺少见肿瘤部分具有典型CT征象。结论肾上腺常见原发性肿瘤具有各自典型CT征象,少见肿瘤部分具有一定的CT特征,认识各自典型CT征象,能做出正确诊断。Objective To analyze the dynamic enhanced CT signs of Adrenal primary tumors. Methods The dynamic enhanced CT manifestations were retrospectively analyzed in 118 adrenal primary tumors confirmed by pathology. Results In 118 adrenal primary tumor,the benign and malignant lesions were 115 and 3,repectively,and the bilateral and unilateral morbidity was 5 and 113 respectively. The morbidity of cortical adenomas,medullary lipoma and pheochromocytoma were 50. 8%（ 60/118）,29. 7%（ 35/118）,9. 3%（ 11/118） in common primary adrenal tumors. The cortical adenomas include unilateral and single lesion with the maximal diameter less than 4 cm. They presented low and homogenous density before contrast administration and mild to moderate enhancement following contrast clear quickly after contrast administration. The medullary lipomas were fatty component. The solid part mild-to-moderate heterogeneous enhanced and fat part was not enhanced. Most of the pheochromocytomas were unilateral with uniform size,heterogenous density in plain CT.And they were remarkable persistent enhancement after contrast administration. The rare adrenal tumors included nodal cells neuroma,adenoid schwannoma,cortical carcinoma,well-differentiated leiomyosarcoma,lipoma,lymphoma,cavernous lymphangioma,cystic teratoma. Some kind of rare adrenal tumors presented characteristics CT signs. Conclusion The common and some of the rare primary adrenal tumors present their own characteristic CT findings. We can make a correct diagnosis when we grasp the CT signs of dynamic enhancement.
