Paragangliomas represent only 10% of chromaffin tissue tumors and those arising from the mesentery seem to be a rare occurrence. We report a case of a 55 year old man in whom an abdominal mass was discovered fortuitously by ultrasonography during a routine health exam. He presented occasional heart palpitations and diaphoresis as well as a well-demarcated mass upon abdominal physical examination. CT scan revealed a solid polylobulated mass in the right lower quadrant. Exploration laparotomy revealed a voluminous multi-nodular tumoral mass, which contained hemorrhagic spots. Histopathological studies confirmed the presence of a paraganglioma. The excision of the mass as well as the surrounding intestine and mesentery also revealed two lymphatic metastases, the first among 14 documented cases to be described concerning mesenteric paragangliomas. One year follow up and CT scan revealed neither recurrence nor the presence of distant metastases.
副神经节瘤仅占嗜铬细胞瘤的 10%，而发生于肠系膜的副神经节瘤似乎更为罕见。我们报告了 1 例 55 岁男性病例，该患者在常规健康检查中偶然通过超声检查发现腹部肿块。他偶尔有心悸和出汗，腹部体检时可触及边界清楚的肿块。CT 扫描显示右下象限有一个实性多叶状肿块。剖腹探查显示一个体积大的多结节肿瘤，其中含有出血点。组织病理学研究证实存在副神经节瘤。肿块的切除以及周围的肠和肠系膜也显示出两个淋巴结转移，这是 14 例已报道的肠系膜副神经节瘤中第一个描述的病例。1 年的随访和 CT 扫描显示既没有复发也没有远处转移。
