INTRODUCTION Lipoma arborescens (LA) is a rare, benign intra-articular lesion most commonly found in the knee, characterised by villous proliferation of the synovium. It generally presents as a longstanding, slowly progressive swelling of one or more joints associated which may or may not be associated with pain. MRI is the investigation of choice, with images clearest on fat-supressed or STIR ...

Lipoma arborescens, a diffuse articular lipomatosis, is a rare disorder characterized by marked villiform synovial proliferation and diffuse replacement of the subsynovial tissue by mature adipocytes. Unilateral joint involvement is the usual presentation while bilateral joint involvement is more uncommon. We reported a case of bilateral lipoma arborescens in a male patient with associated mark...

BACKGROUND With the advent of MRI (Magnetic Resonance Imaging), Synovial lesions around knee are being more and more easily detected. Synovial lesions of knee present with boggy swelling, effusion, pain, and restriction of motion. Differential diagnoses of such lesions include pigmented villonodular synovitis, synovial lipoma, synovial chondromatosis, rheumatoid arthritis, synovial hemangioma, ...

We present a case of lipoma arborescens of the knee in a 17-year-old man, discuss its characteristic imaging findings, and review the relevant differential diagnoses.

lipoma arborescens, also known as villous lipomatous transformation of synovium is an unusual fatty lesion of joint. this disorder is characterized by a diffuse increase in the quantity of subsynovial fat in supra-patellar region which bulges the overlying synovial lining and produces a villous architecture. hereby we report a case of lipoma arborescens in an eleven year old boy with a history ...

Although radiosynovectomy (RS) applications have been carried out for many years, clinical indications of this non-invasive procedure is thought to be limited probably due to the lack of information of clinicians. Clinicians' preferential indication for RS is the treatment-resistant synovitis of individual joints, i.e. despite systemic pharmacotherapy and intra-articular steroid injections. We ...

A 23 year old Asian female presented with swelling of right knee joint for 5 years with history of exacerbations and remissions of symptoms. She was initially diagnosed as a case of suprapatellar bursitis based on clinical and X-ray findings. Further evaluation with higher imaging modalities was pathognomonic of lipoma arborescens. Patient underwent synovectomy and the diagnosis was confirmed h...
