目的：总结肾上腺内外儿茶酚胺分泌性病变的ＣＴ定位经验。材料与方法：分析３３例儿茶酚胺增多症的临床及ＣＴ扫描资料。其中３２例经手术病理证实。１例ＣＴ定位失败，手术切除左肾上腺，病理报告正常，患者１０月后死于心肾功能衰竭。结果：ＣＴ探测肾上腺内嗜铬细胞瘤的准确率为１００％（ｎ＝２３）。１例左肾上腺髓质增生未能定位。ＣＴ定位了９例肾上腺外病灶中的８例功能性副神经节瘤，其发生部位是肾门（ｎ＝４）、主动脉旁（ｎ＝２）、盆腔（ｎ＝１）、膀胱（ｎ＝１）。肾上腺外肿瘤占２７％。作者观察到肾上腺外因素所致的某些高血压患者中，双侧肾上腺可以有中度的增大。结论：肾上腺外儿茶酚胺分泌性病变可发生于颅底至副睾间的任何部位，有时ＣＴ定位非常困难，因此对于有临床生化证据的儿茶酚胺增多症患者，在认真搜寻可能存在的肾上腺外副神经节瘤之前，不宜轻易做出髓质增生的诊断 Objective: To summarize the CT location experience of catecholamine secreting lesions both inside and outside the adrenal gland. Materials and Methods: Clinical and CT scan data of 33 patients with catecholaminemia were analyzed. 32 cases were confirmed by surgery and pathology. One patient had failed CT location. The left adrenal gland was surgically removed and the pathology was normal. The patient died of cardiorenal failure after 10 months. Results: The accuracy of CT in detecting adrenal pheochromocytoma was 100% (n = 23). One case of left adrenal hyperplasia failed to locate. Eight cases of functional accessory ganglioma were localized in 9 cases of extra-adrenal lesions by CT. The sites of the lesions were renal portal (n = 4), aortic (n = 2), pelvic (n = 1) = 1). Adrenal tumors accounted for 27%. The authors observed moderate increases in bilateral adrenal glands in some hypertensive patients caused by extra-adrenal factors. CONCLUSIONS: Extra-adrenal catecholamine-producing secretory lesions can occur anywhere in the base of the skull base to the epididymis, and CT mapping is sometimes difficult. Therefore, in patients with clinically biochemical evidence of catecholaminemia, a careful search for possible extra-adrenal ganglion Before the tumor, it is not easy to make a diagnosis of medullary hyperplasia
