Introduction: Deep circumflex iliac artery (DCIA) aneurysm is a rare cardiovascular condition whose clinical characteristics are largely unknown. Herein, we report a case of retroperitoneal hematoma caused by a ruptured DCIA aneurysm that mimicked a ruptured abdominal aortic aneurysm (AAA).
Case Report: An 87-year-old woman presented to our hospital with sudden onset of severe abdominal pain. Computed tomography (CT) showed a 58-mm AAA and a marked retroperitoneal hematoma. The patient was diagnosed with ruptured AAA and underwent emergency graft replacement. Owing to the persistent hemorrhage, repeat CT evaluation was performed, which revealed a hemorrhage from an aneurysm in the DCIA. Consequently, coil embolization was performed to achieve hemostasis.
Conclusion: Although DCIA aneurysms are uncommon, the possibility should be considered when diagnosing cases of retroperitoneal hemorrhage, as DCIA yields CT findings and symptoms similar to those of a ruptured AAA.
Keywords: Abdominal aortic aneurysm rupture, Deep circumflex iliac artery, Retroperitoneal hemorrhage
