摘　　要：目的探讨CT检查对肾上腺外嗜铬细胞瘤的定位诊断价值。方法回顾性分析经手术和病理检查证实的43例肾上腺外嗜铬细胞瘤的CT表现。结果本组43例患者中,肿瘤位于腹膜后-腹主动脉旁21例,肾门附近8例,髂动脉旁3例,盆腔内2例,膀胱内2例,右心房内1例,肝内下腔静脉旁1例,肝门1例,胰头1例,小肠1例。2例为多发病灶,分别位于腹主动脉旁和下腔静脉旁。瘤体最大者为11cm×13cm,最小为1.5cm×2.0cm。32例为良性病变,瘤体直径<5cm者23例,直径5～10cm者7例,直径>10cm者2例。11例为恶性肿瘤,其中1例并两肺多发转移结节,1例并多发骨转移,1例并肝内多发转移和脊柱多发转移,瘤体直径均>5cm,其中>10cm者4例。CT定位符合率达100.0%(43/43),CT诊断符合率达93.0%(40/43)。结论CT对肾上腺外嗜铬细胞瘤的定位诊断具有重要的临床价值。Objective To evaluate the diagnostic value of CT in locating extra-adrenal pheochromocytoma. Methods The CT findings of 43 patients with surgically and pathologically confirmed extra-adrenal pheochromocytoma were retrospectively analyzed. Results The locations of the extra-adrenal pheochromocytomas in our group included the areas surrounding the abdominal aorta（21/43） and renal hilum （8/43）, the right atrium （ 1 ）, hepatic inferior vena cave （ 1 ）, hepatic hilum （ 1 ）, head of pancreas （ 1 ）, small intestine （1）, around the iliac artery （3）, pelvis （2）, and the bladder （2） ; there were 2 patients with multiple tumors para-aorta and by inferior vena cave. The maximal tumor size was 11 cm × 13 cm and the minimal size was 1.5 cm × 2.0 cm. There were 32 benign cases, with 23 smaller than 5 cm in diameter, 7 within 5- 10 cm, and 2 larger than 10 cm. Eleven cases had malignant tumors, including one with pulmonary metastasis, one complicated by bone metastasis, and one with liver metastasis and spine metastasis; all the diameters were larger than 5 cm and 4 larger than 10 cm. Eleven of the 43 cases had malignant tumors according to the post-operative pathologic diagnosis. The locating rate of CT was 100% （43/43） and the diagnosis rate was 93% （40/43）. Conclusion CT is highly effective in localizing extra-adrenal pheochromocytoma. （Shanghai Med J,2009,32 ： 102-104）
