目的:分析腹膜后异位嗜铬细胞瘤的CT影像学结果,探讨其特异性的CT表现。方法:回顾性分析5例经病理证实为腹膜后异位嗜铬细胞瘤患者的临床、手术及CT资料。结果:5例均为单发肿块,位于腹主动脉周围,CT平扫表现为境界清楚的圆形或椭圆形肿块,肿块直径3CM~7CM,平均4.5CM,瘤体密度较均匀,无囊变和坏死,增强后呈明显较均匀强化。结论:腹膜后异位嗜铬细胞瘤常位于腹主动脉旁,CT增强显示腹主动脉旁类圆形富血供软组织肿块,若临床合并高血压,应高度警惕嗜铬细胞瘤的可能。
Objective: To analyze CT findings of retroperitoneal ectopic pheochromocytoma and to explore its specific CT findings. Methods: The clinical, surgical and CT data of 5 patients with pathologically confirmed retroperitoneal pheochromocytoma were analyzed retrospectively. Results: All the 5 cases were single mass and located around the abdominal aorta. The CT scan showed a clear circular or oval mass with a diameter of 3CM ~ 7CM, an average of 4.5CM. The tumor density was more uniform and no cystic change And necrosis, was significantly enhanced after enhanced significantly. CONCLUSIONS: Retroperitoneal pheochromocytoma is usually located beside the abdominal aorta. The CT enhancement shows that the abdominal aorta is round and round with blood supply for soft tissue mass. If clinical hypertension is complicated, the possibility of pheochromocytoma should be highly alert.
