Synovial hemangioma of Hoffa fat pad is an extremely rare disease, which occurs in the knee joints. Because synovial hemangioma often shows nonspecific symptoms, such as pain, swelling, limping, or limitation of motion, diagnosis could be delayed in many cases. We present a 7-year-old boy referred to our department for Tc red blood cell (RBC) scan for the confirmation of hemangioma suggested by the MRI. RBC scan demonstrated intense radioactivity accumulation in Hoffa pad of right knee joint, and subsequent excision biopsy revealed the mass as venous hemangioma.
髌下脂肪垫滑膜血管瘤是一种极为罕见的疾病，主要发生在膝关节。由于滑膜血管瘤常表现为非特异性症状，如疼痛、肿胀、跛行或运动受限，因此在许多情况下可能会延迟诊断。我们报告了一例 7 岁男孩，因 MRI 提示为血管瘤，转诊至我科行 Tc 红细胞（RBC）扫描以明确诊断。RBC 扫描显示右膝关节髌下脂肪垫放射性摄取明显增高，随后行切除活检显示肿块为静脉性血管瘤。
