We report a 84-year-old man with an aneurysm of the superficial femory artery (SFA). Primarily, after B-mode sonography soft tissue neoplasm was suspected and sectional MR imaging was performed for further diagnostics. Because of blood flow related ghost artifacts, sectional MR led to the diagnosis of an partially thrombosed aneurysm without angiography. Initially, the differential diagnosis of an SFA aneurysm, which is extremely rare, has not been considered. Soft tissue neoplasms may have a similar appearance to partially thrombosed aneurysms. This case demonstrate the importance to notice also artifacts in sectional MRI which can give important informations for correct diagnosis.
我们报告了一名84岁患有股浅动脉（SFA）动脉瘤的男性患者。起初，B超检查怀疑为软组织肿瘤，遂进行断层磁共振成像（MR）以进一步诊断。由于血流相关的伪影，断层MR在未进行血管造影的情况下诊断出部分血栓形成的动脉瘤。最初，未考虑极其罕见的SFA动脉瘤的鉴别诊断。软组织肿瘤可能与部分血栓形成的动脉瘤外观相似。该病例表明，在断层MRI中注意伪影很重要，其可为正确诊断提供重要信息。
