目的：探讨肾上腺外嗜铬细胞瘤的诊断和治疗。方法：回顾性分析１６ 例本病患者的临床资料。结果：肾上腺外嗜铬细胞瘤１６ 例，占同期嗜铬细胞瘤２３．７％ ，１２ 例有高血压症状，无症状４例。全部病例均手术切除肿瘤，无手术并发症。结论：血和尿儿茶酚胺及其代谢产物测定对本病定性有很高的诊断价值，定位诊断依靠Ｂ超和ＣＴ。术前应使用肾上腺素能受体阻滞剂控制血压和心率，并扩充血容量。恶性嗜铬细胞瘤的诊断主要靠长期的临床随访
Objective: To investigate the diagnosis and treatment of extra-adrenal pheochromocytoma. Methods: Retrospective analysis of clinical data of 16 patients with this disease. Results: 16 cases of extra-adrenal pheochromocytoma, accounting for 23.7% of pheochromocytoma at the same time, 12 cases had hypertension symptoms, 4 cases were asymptomatic. All cases were surgically resected with no complications. Conclusion: The determination of blood and urinary catecholamines and their metabolites have a high diagnostic value for the characterization of the disease, and the localization diagnosis depends on ultrasound and CT. Preoperatively, adrenergic receptor blockers should be used to control blood pressure and heart rate, and to expand blood volume. The diagnosis of malignant pheochromocytoma relies on long-term clinical follow-up
