is an anaerobic, partially acid-fast, Gram-positive bacillus associated with abscess formation. We present the case of a 70-year-old male with chronic contained rupture of abdominal aortic aneurysm (CCR-AAA) complicated by intra-abdominal abscess formation. An abdominal computed tomography scan revealed a rim-enhancing retroperitoneal collection tracking into the subcutaneous layer of the left flank and buttock, suggestive of CCR-AAA with infected haematoma. He underwent ultrasound-guided needle aspiration of the intra-abdominal collection. Conventional culture techniques failed to isolate , and the diagnosis was only confirmed by means of 16S rRNA PCR. The patient underwent branched endovascular repair of his aneurysm, and was commenced on treatment with co-amoxiclav, resulting in significant reduction in the size of the infected collection. This is only the second reported case of infection with in the UK, and the first reported case of this organism causing infected CCR-AAA.
是一种与脓肿形成相关的厌氧、部分抗酸、革兰氏阳性杆菌。我们报告一例70岁男性，患有慢性腹主动脉瘤局限性破裂（CCR - AAA）并伴有腹腔内脓肿形成。腹部计算机断层扫描显示一个边缘强化的腹膜后积液延伸至左侧腰部和臀部的皮下层，提示CCR - AAA合并感染性血肿。他接受了超声引导下腹腔积液穿刺抽吸。传统培养技术未能分离出该菌，诊断仅通过16S rRNA聚合酶链反应得以证实。患者接受了动脉瘤分支血管内修复术，并开始使用阿莫西林克拉维酸治疗，感染性积液大小显著缩小。这是英国第二例报告的该菌感染病例，也是首例该菌导致感染性CCR - AAA的报告病例。
