肾上腺占位病变的多层螺旋CT诊断及鉴别诊断

Multi-slice spiral CT diagnosis and differential diagnosis of adrenal masses

目的探讨多层螺旋CT对肾上腺占位病变的诊断及鉴别诊断价值。方法回顾性分析经手术病理证实的53例肾上腺占位病变的多层螺旋CT表现特征，所有病例均行多层螺旋CT平扫及增强扫描。结果本组53例共有64个病灶：皮质腺瘤15例21个病灶，嗜铬细胞瘤18例21个病灶。皮质腺癌6例6个病灶，转移瘤4例6个病灶，神经母细胞瘤5例5个病灶，淋巴瘤1例1个病灶，肾上腺囊肿2例2个病灶，节细胞神经瘤2例2个病灶。结论大多数肾上腺占位病变的表现具有一定特征。多层螺旋CT对肾上腺占位病变的诊断及鉴别诊断有重要价值，结合临床及生化检查可显著提高诊断的准确率。

Objective To evaluate the value of multi-slice spiral CT scanning in diagnosis and differential diagnosis of adrenal masses. Methods The CT features of 53 patients with adrenal masses proved by operation and pathology were analyzed retrospectively. Plain and enhanced scanning were done by multi-slice spiralCTin all patients. Results Sixty-four focuses （53 patients） were found,21 focuses（15 patients） were adenoma,21 focuses（ 18 patients） were pheochromocytoma,6 focuses（6patients） were ade,6 focuses（4 patients） were metastasis tumor,5 focuses （5 patients） were neuroblastoma, 1 focus （ 1 patient） were lymphoma, 2 focuses （2 patients） were adrenal gland cyst, and 2 focuses （2 patients ） were ganglioneuroma. Conclusions Most adrenal masses have certain characteristics. Multi-slice spiral CThas important value in diagnosis and differential diagnosis of adrenal masses. Multi-slicespiral CT findings combined with clinical and laboratory data can improve accuracy in adrenal masses diagnosis.
