Introduction: Lipoma arborescens is a very rare pseudo-tumoral lesion of unknown etiology, characterized by lipomatous infiltration of subsynovial stroma, bilateral involvement is exceptional, only eight cases are reported in the literature.
Presentation Of Case: We report the very rare case of two men presented at our department with complaints of swelling of both knees and intermittent joint effusion, Surgical biopsy revealed Lipoma arborescens in both cases. Open total synovectomy was performed. Follow-up evaluation showed no signs of recurrence.
Discussion And Conclusion: Lipoma arborescens is a rare entity, the unilateral form affecting the knee is the most common, with a predilection for suprapellar recess. Magnetic resonance imaging (MRI) is the examination of choice showing multiple villous proliferation of the synovium and fat-like cells, with a fatty signal on all sequences. Treatment by open or arthroscopic synovectomy offers the best outcomes.

Rationale: Lipoma arborescens (LA) is a rare, benign proliferative disorder of the synovial lining that typically affects middle-aged individuals, predominantly in the knee joint. However, its occurrence in younger patients is unusual and may pose unique diagnostic and therapeutic challenges. This case report aims to highlight the clinical, imaging, and therapeutic aspects of LA in a young adult, thereby expanding the understanding of its presentation in this age group.

The periarticular adipose tissues play a crucial role in knee biomechanics, yet they are often overlooked in daily radiology practice. As the primary mechanical shock absorbers of the knee, intra-articular fat pads reduce the friction between intra-articular structures during joint movement. They also contribute to inflammatory regulation, endocrine secretion, and pain detection.

Article Synopsis
- Synovial lipomatosis is a rare, benign condition affecting the synovial lining of joints, primarily the knee, and is characterized by the presence of mature fat infiltrating the joint tissue, causing pain and swelling.
- It typically leads to joint movement restrictions and can occur in other joints like the hip and ankle, but diagnosis is often challenging due to its rarity and unclear causes.
- Treatment options range from conservative management to surgical intervention; in this case, a 47-year-old male underwent surgery for severe symptoms, including arthroscopic debridement and synovectomy.

Synovial lipomatosis or lipoma arborescens is a very uncommon pseudo-tumorous lesion of the synovium which more commonly affects the knee joint. The most probable cause of this pathological lesion is degenerative articular disorders of the joint and improper fat accumulation. It is characterized by presence of villous proliferation of the synovium and replacement of the sub-synovial tissue by mature adipocytes which is infiltrated by dense chronic inflammatory cells like lymphocytes, plasma cells and eosinophils.
