Intra-articular synovial haemangioma of the knee is a benign tumour. However, diagnostic delay leads to degenerative changes in the cartilage and osteoarthritis due to recurrent haemarthrosis. Therefore, treatment should be performed immediately. We report the case of a localized synovial haemangioma arising from the medial plica in a 38-year old female presenting with pain and restricted range of motion in the right knee joint. Initially, we diagnosed this case as a localized pigmented villonodular synovitis (LPVS) based on MRI and arthroscopic findings and performed only arthroscopic en bloc excision of the mass and synovectomy around the mass for diagnostic confirmation. Fortunately, there was no difference in the treatment approaches for LPVS and localized haemangioma and the synovial haemangioma had not recurred at the 3-month postoperative follow-up with MRI. The patient's clinical symptoms resolved and had not relapsed two years after surgery.
膝关节内滑膜血管瘤是一种良性肿瘤。然而，诊断延迟会因反复关节积血导致软骨退变和骨关节炎。因此，应立即进行治疗。我们报告一例38岁女性患者，其右膝关节内侧皱襞出现局限性滑膜血管瘤，表现为疼痛和活动范围受限。最初，基于MRI和关节镜检查结果，我们将该病例诊断为局限性色素沉着绒毛结节性滑膜炎（LPVS），仅进行了关节镜下整块切除肿块及肿块周围滑膜切除术以进行诊断确认。幸运的是，LPVS和局限性血管瘤的治疗方法并无差异，术后3个月MRI随访时滑膜血管瘤未复发。患者的临床症状在术后两年得到缓解且未复发。
