Lipoma arborescens is a villous lipomatous proliferation of the synovial membrane characterized by chronic and painless synovial effusion. The aetiology is unknown. It has to be included in the differential diagnosis of chronic monoarticular disease in childhood. Magnetic resonance imaging provides a highly efficient tool for the diagnosis of this very rare condition. This is indeed the fourth paediatric case reported. Rather than resorting to the often inconvenient surgical synovectomy commonly recommended, we chose to treat the knee of this 13-yr-old boy with intra-articular osmic acid.
树枝状脂肪瘤是一种滑膜的绒毛状脂肪增生，其特征为慢性无痛性滑膜积液。病因不明。它必须纳入儿童慢性单关节疾病的鉴别诊断中。磁共振成像为诊断这种非常罕见的疾病提供了一种高效的工具。这确实是报道的第四例儿科病例。我们没有采用通常推荐的往往不方便的手术滑膜切除术，而是选择用关节内注射锇酸来治疗这个13岁男孩的膝盖。
