 • Lipoma arborescens is a nonneoplastic uncommon synovial entity occuring in the lining of joints, bursae, and tendons causing recurrent painless joint swelling and effusion in a wide age range. • Diffuse replacement of subsynovial mature fatty cells associated with villous proliferation of synovium forming typical frond-like appearance is the major histopathologic finding in which MRI is the most effective method in radiologic aspect. • Lipoma arborescens should be included in the differential diagnosis of recurrent joint swelling and effusion among other synovial pathologies such as pigmented villonodular synovitis, synovial lipoma, rheumatoid arthritis, synovial hemangioma, synovial chondromatosis. • Lipoma arborescens is a benign entity of which radiologists and pathologists should increase their familiarity about it and MRI is the problem solving tool before biopsy , arthroscopy or synoviectomy.    

• Histopathological definition and incidence of lipoma arborescens • Multimodalitary imaging and histopathological findings of various cases • Differential diagnosis of lipoma arborescence among other synovial diseases
