Abstract

Lipomaarborescens is a chronic, slowly progressive intra-articular condition characterised by villous lipomatous proliferation of the synovium, usually involving the suprapatellar pouch of the knee joint. It is an uncommon cause of intra-articular masses that presents as slowly progressive painless swelling of the joint, which persists for many years and is assosciated with intermittent effusions. We present this condition to raise awareness of its clinical spectrum and imaging features, so that early diagnosis and appropriate treatment can be given, and misdiagnosis of this type of rare benign condition as other more complex intraarticular masses is avoided.
