摘　　要：目的探讨螺旋CT扫描对肾上腺肿瘤及肿瘤样病变的诊断及鉴别诊断价值。方法回顾性分析65例共73个肾上腺肿瘤及肿瘤样病变的CT表现,与手术病理对照。结果65例肾上腺占位病变中,肾上腺增生12例,腺瘤18例,皮质癌7例,肾上腺转移癌11例,嗜铬细胞瘤7例,髓样脂肪瘤4例,神经节瘤2例,肾上腺畸胎瘤、血肿、囊肿及结核各1例。肾上腺良性病变直径多小于3cm,边界清晰(73.9%,34/46),48.4%的恶性肿瘤直径大于3cm。肾上腺转移瘤多双侧发病(6/11)。4例肾上腺髓脂瘤均呈脂肪为主型。结论螺旋CT扫描对肾上腺病变的诊断及鉴别诊断具有重要价值,并有助于选择治疗方案和判断预后。Objective To discuss the value of spiral CT scanning in the diagnosis and differential diagnosis of adrenal tumors and tumor-like lesions. Methods CT findings of 73 adrenal tumors and tumor-like lesions in 65 patients were retrospectively analyzed and compared with pathology. Results Among 65 patients, adrenal hyperpalasia was found in 12,adenoma in 18, adrenocortical carcinoma in 7, metastatic tumors in 11, pheochromocytoma in 7, myelohpoma in 4, ganglioneuroma in 2, and teratoma, hematoma, c^st,tuhercul.~sis in 1 each.CT features between benign and malignant lesions were obviously different. The diameter of most benign lesions （73.8%）was less than 3 cm, while that of 48.4% malignant lesions was greater than 3 cm. The metastatic tumors more than 50% were bilateral. All the 4 cases of myelolipoma wese dominantly fatty component. Conclusion Spiral CT scanning has important value in the diagnosis and differential diagnosis of adrenal lesions and it is helpful to select the therapeutic protocol and to identify the prognosis.
