Lipoma arborescens (LA) is a rare benign neoplasm affecting large synovial joints, most commonly seen in the knee joint. Unlike other common swellings around the knee joint, LA is intra-articular and can lead to degenerative changes in the knee joint due to mechanical impingement. The importance of correct diagnosis with characteristic MR and macroscopic appearance and appropriate surgical treatment is outlined in this case report.
树枝状脂肪瘤(LA)是一种罕见的良性肿瘤,累及大的滑膜关节,最常见于膝关节。与膝关节周围的其他常见肿胀不同,LA位于关节内,由于机械撞击可导致膝关节发生退行性改变。本病例报告概述了通过特征性磁共振成像(MR)和宏观表现进行正确诊断以及进行适当手术治疗的重要性。
