嗜铬细胞瘤是产生儿茶酚胺的肿瘤,主要来源于神经外胚层有分泌作用的chromograffin细胞。在普通人群中发生率大约为0.01％～0.001％,胸部嗜铬细胞瘤只占所有嗜铬细胞瘤的1％～2％,且报道中最多位于后纵隔,心包内嗜铬细胞瘤极为罕见。作者对1981年～1993年间发现的12例经手术证实的心包内嗜铬细胞瘤影像特征做了回顾性研究。
Pheochromocytoma is a catecholamine-producing tumor that is primarily derived from chromograffin cells that have a secretory role in the neuroectodermal layer. The incidence in the general population is approximately 0.01% to 0.001%. Chest pheochromocytoma only accounts for 1% to 2% of all pheochromocytoma, and is most often reported in the posterior mediastinum. Pheochromocytoma in the pericardium is extremely rare. The authors retrospectively studied the imaging features of 12 surgically confirmed pericardial pheochromocytomas found between 1981 and 1993.
