目的:探讨成人肾上腺肿瘤性病变的CT特点,以提高诊断与鉴别诊断的能力。方法:回顾性分析经手术病理或临床证实的74例成人肾上腺肿瘤性病变的CT表现。结果:肾上腺良性肿瘤39例,其中肾上腺腺瘤18例,良性嗜铬细胞瘤3例,肾上腺囊肿7例,肾上腺节细胞神经瘤3例,肾上腺髓脂瘤6例,肾上腺神经鞘瘤2例;恶性肿瘤35例,其中肾上腺皮质癌2例,肾上腺转移瘤31例,恶性嗜铬细胞瘤2例。结论:CT平扫及增强能较好地显示肾上腺肿瘤性病变的内部结构和影像学特点,反映病变的血供情况和病理特征,有助于肾上腺肿瘤的诊断与鉴别诊断。

CT diagnosis and differential diagnosis of adult adrenal tumor

Objective To explore the CT characteristics of adrenal tumors in adults, in order to improve the diagnosis and differential diagnosis. Method A retrospective analysis was on CT manifestations in 74 adults with adrenal tumor by surgery pathology or clinical confirmed. Results Thirty -nine patients with benign adrenal tumor,including 18 cases of adrenal adenoma,3 cases of benign pheochromocytoma,7 cases of adrenal cysts,3 cases of adrenal ganglioneuroma,6 cases of adrenal myelolipoma and 2 cases of adrenal schwannoma;35 cases of malignant tumors, including 2 cases of adrenal cortical carcinoma,31 cases of adrenal metastatic tumor, and 2 cases of malignant pheochromocytoma. Conclusion CT scan and enhanced scan can display the internal structure and imaging features better in adrenal tumor lesions, reflect the blood supply of lesions and pathological features, and is contribute to the diagnosis and differential diagnosis of adrenal tumor.
