目的探讨滑膜血管瘤的影像学表现及临床诊断价值。资料与方法回顾性分析经病理证实的16例(男9例,女7例)滑膜血管瘤患者资料,其中膝关节14例,肘关节1例,髋关节1例。X线平片检查13例,CT平扫1例,MRI平扫及增强扫描15例,血管造影1例。结果 X线平片可见软组织肿胀、静脉石、软组织肿块表现。CT表现为软组织肿胀及骨质侵蚀。血管造影见毛细血管期及静脉期对比剂滞留。MRI显示肿块T1WI呈等低信号,T2WI呈“葡萄串”样高信号或不均匀等低信号,其内见条索状或网格状低信号分隔。MRI表现各异由病理组织成分不同所决定。结论 X线平片、CT、血管造影对滑膜血管瘤定性诊断价值有限,MRI对滑膜血管瘤的定位及定性诊断具有重要价值,是术前诊断的首选方法,对治疗方案的选择具有指导作用。
Objective To investigate the imaging findings and clinical diagnostic value of synovial hemangiomas. Materials and Methods Data of 16 patients (9 males and 7 females) with synovioma confirmed by pathology were retrospectively analyzed. There were 14 cases of knee joint, 1 case of elbow joint and 1 case of hip joint. X-ray plain film examination in 13 cases, CT plain scan in 1 case, MRI plain scan and enhanced scan in 15 cases, angiography in 1 case. Results X-ray showed soft tissue swelling, vein stone, soft tissue mass performance. CT showed soft tissue swelling and bone erosion. Angiography see capillary period and venous phase contrast agent retention. MRI showed that the tumor T1WI showed low signal, T2WI was “grape bunch” -like high signal or uneven low signal, which see the cord-like or grid-like low signal separation. MRI manifestations vary by the composition of the pathological tissue determined. Conclusions X-ray, CT and angiography are of limited value in the qualitative diagnosis of synovial hemangiomas. MRI is of great value in the localization and qualitative diagnosis of synovial hemangiomas. It is the first choice for preoperative diagnosis and is helpful for the selection of treatment options effect.
