本文介绍一例以胸痛、呼吸困难为主要表现,反复发生非心源性肺水肿、持续性低血压和急性冠脉综合征的囊性嗜铬细胞瘤患者。囊性嗜铬细胞瘤合并多种严重并发症临床上少有报道,容易误诊和漏诊。对于出现肺水肿、持续性低血压和急性冠脉综合征等严重体征,临床诊断又不明确的患者,需要考虑嗜铬细胞瘤的可能。 This article presents a case of cystic pheochromocytoma patients with chest pain, dyspnea as the main manifestation, recurrent non-cardiac pulmonary edema, persistent hypotension and acute coronary syndrome. Cystic pheochromocytoma with a variety of serious complications clinically rare, easy misdiagnosis and missed diagnosis. For patients with severe signs of pulmonary edema, persistent hypotension, and acute coronary syndromes that are not clearly identified for clinical diagnosis, the possibility of pheochromocytoma needs to be considered.
