A 64-year-old man presented to our hospital feeling ill with epigastralgia. Computed tomography (CT) showed right suprarenal cystic tumor. High urinary catecholamine level was noted. Based on metaiodobenzylguanidine (MIBG) scintigraphy, magnetic resonance imaging and blood tests, preoperative diagnosis was adrenal pheochromocytoma. En-bloc resection of the tumor and the right kidney was performed. The cyst contained yellowish serous fluid, which had a catecholamine level about 3,000 times that in the blood. The histological diagnosis was cystic pheochromocytoma. Pathogenesis of cystic adrenal tumor is discussed briefly.
一名64岁男性因上腹部疼痛不适前来我院就诊。计算机断层扫描（CT）显示右肾上腺囊性肿瘤。检测发现尿儿茶酚胺水平升高。基于间碘苄胍（MIBG）闪烁显像、磁共振成像和血液检查，术前诊断为肾上腺嗜铬细胞瘤。遂行肿瘤及右肾整块切除。囊肿内为淡黄色浆液性液体，其儿茶酚胺水平约为血液中的3000倍。组织学诊断为囊性嗜铬细胞瘤。本文简要讨论了肾上腺囊性肿瘤的发病机制。
