We describe a case of a 63-year-old man with chronic-contained rupture of an abdominal aortic aneurysm at the site of prior graft repair of the aneurysm. Initially misinterpreted as osteomyelitis on the basis of CT findings, this chronic-contained rupture of the abdominal aorta eroding the vertebrae was preoperatively diagnosed at MR imaging and confirmed at surgery. A conventional angiogram failed to show the pseudoaneurysm. Owing to a major difference in the management of a contained aortic aneurysm rupture versus that for osteomyelitis, MR imaging with CT or MR angiography is recommended before any operative or invasive procedure.
我们描述了一例63岁男性患者，其腹主动脉瘤在先前动脉瘤移植修复部位发生慢性局限性破裂。最初根据CT表现被误诊为骨髓炎，这种侵蚀椎体的腹主动脉慢性局限性破裂在术前经磁共振成像（MR）诊断，并在手术中得到证实。传统血管造影未能显示假性动脉瘤。由于局限性主动脉瘤破裂与骨髓炎的治疗方法有很大差异，因此在进行任何手术或侵入性操作之前，建议进行CT或MR血管造影的MR成像检查。
