Abstract

Lipoma arborescens (diffuse articular lipomatosis) is a rare, benign intra-articular lesion of unknown aetiology. It is characterised by villous proliferation of the synovium and diffuse replacement of the subsynovial tissue by mature fat cells. It forms part of the differential diagnosis for a slowly progressive chronically swollen knee. We present a very rare case of bilateral involvement of the knee and discuss the symptoms, diagnosis and treatment of this condition.

摘要

树枝状脂肪瘤（弥漫性关节脂肪瘤病）是一种病因不明的罕见良性关节内病变。其特征为滑膜的绒毛状增生以及成熟脂肪细胞对滑膜下组织的弥漫性替代。它是慢性膝关节缓慢进展性肿胀鉴别诊断的一部分。我们报告一例极为罕见的双侧膝关节受累病例，并讨论该疾病的症状、诊断及治疗。
