Abstract：
A 53-year-old woman with a history of recurrent right lower quadrant pain presented with slightly bloody stools in April 2023. She was initially diagnosed with acute diverticulitis using an abdominal computed tomography (CT) scan and was treated conservatively. On the second day, however, she reported significant hematochezia. A subsequent contrast-enhanced CT scan revealed an extravasation in the ascending colon, which was promptly managed with colonoscopy. Despite initial hemostasis, she experienced recurrent bleeding. Another contrast-enhanced CT scan revealed a pseudoaneurysm with ongoing extravasation in the same area. Angiography confirmed a pseudoaneurysm in a branch of the ileocolic artery, which was successfully treated by embolization. She was discharged after an 18 day hospital stay. This case highlights a pseudoaneurysm caused by diverticulitis.
摘要：
2023年4月，一名53岁的女性，有复发性右下腹疼痛的病史，出现轻微的血便。最初使用腹部计算机断层扫描（CT）扫描将她诊断为急性憩室炎，并进行了保守治疗。第二天,然而,她报告了严重的便血。随后的对比增强CT扫描显示升结肠外渗，通过结肠镜检查迅速进行。尽管最初止血,她反复出血.另一次对比增强CT扫描显示，同一区域存在假性动脉瘤并持续外渗。血管造影证实回肠动脉分支有假性动脉瘤，经栓塞成功治疗。她在住院18天后出院。该病例突出了由憩室炎引起的假性动脉瘤。
