Abstract

This report describes a patient with lipoma arborescens presenting as hemarthrosis of a knee with intraosseous lesions. A 44-year old woman complained of pain and swelling of left knee. Arthrocentesis resulted in bloody effusion. Magnetic resonance images showed villous projecting frondlike fatty soft tissue proliferation in the suprapatellar pouch and ovoid intraosseous lesions in proximal tibia. The soft tissue mass was removed through arthroscopic synovectomy and the biopsy of the mass confirmed the diagnosis. The intraosseous lesions were not considered as a cause of hemarthrosis. We failed to find the exact cause of hemarthrosis. The patient remained asymptomatic after removal of the mass for 10 months. As far as we know, this is the first report of hemarthrosis associated with lipoma arborescens in korea.
