摘要 目的:探讨嗜铬细胞瘤的CT表现特征及其鉴别诊断。方法:回顾性分析53例经病理证实的嗜铬细胞瘤CT表现,并与肾上腺腺瘤、肾上腺腺癌病例进行对比分析。结果:嗜铬细胞瘤多单侧发病,瘤体常较大,边界清楚,瘤体密度不均匀,其内可见坏死和囊变;增强扫描后瘤体实质部分或囊壁持续明显强化。恶性嗜铬细胞瘤CT表现为瘤体较大,边缘呈分叶状,常包埋临近大血管,浸润临近器官,局部有淋巴结转移或远处转移。结论:嗜铬细胞瘤的CT表现具有特征性,虽与某些肿瘤有一定重叠,但结合临床症状及实验室检查多可明确诊断。 Objective:To investigate the CT characteristics and differential diagnosis of pheochromocytoma.Methods:CT findings of 53 cases with pathology proved pheochromocytoma were analyzed retrospectively and compared with that of adrenal adenoma and adrenal carcinoma.Results:Most of pheochromocytomas were unilateral,with large size,well-defined boundary and inhomogeneous attenuation accompanied with necrosis and cystic change.Solid component and cystic wall of the pheochromocytoma enhanced consistently and obviously after contrast administration.Malignant pheochromocytomas mostly were large in size,lobulated in shape,with encasement of adjacent large blood vessels,invasion of neighboring organs and had lymph nodes and distant organs metastases.Conclusion:Characteristic CT features could be revealed in pheochromocytomas.Although the CT findings might be overlapped with other tumors,yet definite diagnosis could mostly be obtained when correlated with clinical and laboratory findings.
