Its association with ruptured abdominal aortic aneurysm is extremely rare.<\/jats:p>\n <\/jats:sec>\n \n Case Presentation<\/jats:title>\n \n A 57\u2010year\u2010old man with no significant medical history presented with sudden abdominal pain and hemorrhagic shock. Computed tomography revealed a ruptured infrarenal abdominal aortic aneurysm, and emergency endovascular aneurysm repair was successfully performed. Preoperative imaging incidentally detected a hypervascular left adrenal mass. Although biochemical findings were borderline,\n 123<\/jats:sup>\n I\u2010metaiodobenzylguanidine scintigraphy demonstrated intense uptake, leading to a diagnosis of pheochromocytoma. After appropriate \u03b1\u2010adrenergic blockade, elective laparoscopic adrenalectomy was safely performed, and histopathology confirmed pheochromocytoma.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n This case highlights the importance of considering pheochromocytoma as an underlying cause of ruptured abdominal aortic aneurysm and demonstrates that a staged strategy with emergency endovascular repair followed by definitive endocrine surgery can be safe and effective.<\/jats:p>\n
