| 摘 要： | 目的探讨踝关节扭伤后假性动脉瘤形成(pseudoaneurysm following ankle sprain,PAFAS)的影像学表现,推测其可能的发病原因。资料与方法搜集1例经手术证实的具有完整临床及影像学资料的PAFAS病例,并结合11篇文献资料分析。结果平片及CT平扫能显示踝关节软组织肿胀、邻近骨质吸收及骨赘形成;MRI平扫T2WI见洋葱样分层软组织肿胀伴粗大搏动伪影,MRI增强扫描显示显著强化瘤腔鸟嘴样突起与供血动脉相连。超声可显示瘤腔紊乱血流及附壁血栓。血管造影检查可显示动脉瘤染色、供血动脉及侧支血管。12例PAFAS中,5例由胫前动脉供血,6例由腓动脉供血,1例同时由胫前动脉和腓动脉供血。结论 PAFAS的影像学检查首选超声,CT、MRI增强扫描或血管成像检查可做出定性诊断,金标准仍然是动脉血管造影检查。PAFAS可能与解剖学基础、机械力作用、炎症介质损伤及踝关节活动频度大等因素有关。 |

| Abstract: | Objective To explore the imaging characteristics of pseudoaneurysm following ankle sprain(PAFAS),and to presume the possible reason of PAFAS.Materials and Methods One case of PAFAS which had comprehensive clinical and imaging data was collected and analyzed combine with literature.Results X-ray and plain CT showed swollen soft tissue,bone absorption and osteophyte.MRI showed onion-layer swollen soft tissue with roughly impulse-artifact on T2WI.Enhanced MRI showed obvious enhancement aneurysm-cavity connecti... |
