Synovial lipomatous proliferations are uncommon idiopathic lesions. Suprapatellar synovial plicae commonly are diagnosed with mechanical knee problems. However, it is not widely known that these plicae can isolate the suprapatellar pouch from the rest of the knee joint. We describe a case of complete bilateral compartmentalization of the suprapatellar pouch (plica synovialis suprapatellaris) in which a 10-year-old boy developed articular tumors isolated in this area. Arthroscopic synovectomy specimens revealed the lesions to represent lipoma arborescens. Rheumatologists should be aware of these two findings when examining a child with swollen knee.
滑膜脂肪瘤样增生是罕见的特发性病变。髌上滑膜皱襞通常与膝关节机械性问题相关。然而，这些皱襞可将髌上囊与膝关节其他部分分隔开来，这一点并不广为人知。我们描述了一例髌上囊（髌上滑膜皱襞）完全双侧分隔的病例，一名10岁男孩在此区域出现了孤立的关节肿瘤。关节镜下滑膜切除术标本显示病变为树状脂肪瘤。风湿病学家在检查膝关节肿胀的儿童时应注意这两种情况。
