LA presents with chronic painlessswelling. Diagnosis is easily done by specific signs of LA onmagnetic resonance imaging (MRI). Typically, LA is treated byopen or arthroscopic synovectomy. A 30-year-old male patient wasadmitted with swelling in his right knee. He had chronic swellingof the suprapatellar bursa with recurrent episodes of effusion in hisright knee for 1 year. He was diagnosed with LA by monitoringsynovial villous proliferations that signal isointense with adiposetissue in all sequences on MRI. LA is a disease that should beremembered in patients with recurrent effusions in the knee joint.MRI plays an important role in diagnosis.
