Lipoma arborescens is a rare intra-articular lesion consisting of a villous lipomatous proliferation of the synovial lining. This case report draws attention to the history, physical findings, and arthroscopic appearance of lipoma arborescens, a rare lesion of the synovial lining of the knee. Arthroscopically, the lesion appears as a synovial lesion with numerous fatty-appearing globules and villous projections. In addition, magnetic resonance imaging is a valuable tool to differentiate the lesion from rheumatoid arthritis, pigmented villonodular synovitis, and synovial chondromatosis in those patients who present with a chronic, swollen, and painful joint.
树枝状脂肪瘤是一种罕见的关节内病变，由滑膜衬里的绒毛状脂肪增生组成。本病例报告关注树枝状脂肪瘤这一膝关节滑膜衬里的罕见病变的病史、体格检查结果及关节镜表现。在关节镜下，该病变表现为一个滑膜病变，有许多呈脂肪样的小球和绒毛状突起。此外，对于那些出现慢性、肿胀且疼痛关节的患者，磁共振成像（MRI）是一种将该病变与类风湿关节炎、色素沉着绒毛结节性滑膜炎及滑膜软骨瘤病相鉴别的重要工具。
