Kronik diz effüzyonunun nadir bir sebebi: Lipoma arborescens

Lipoma arboresens (LA) genellikle dizde görülen nadir birintraartiküler benign lezyondur. LA, kronik ve ağrısız şişlik ilepresente olur. Tanı, manyetik resonans görüntülemede (MRG)LA’ya ait spesifik görüntülerin izlenmesi ile kolaylıkla konulur.Tedavisi sinoviyektomidir. Bu yazımızda, 30 yaşında sağ dizdeLA tanısı konulan bir hasta sunuldu. Hastanın 1 yıldır sağ dizindetekrarlayan effüzyon atakları ile birlikte suprapatellar poşta kronikşişliği vardı. MRG’de tüm sekanslarda yağ doku ile izointenssinyal veren sinoviyal villöz proliferasyonların izlenmesi ilehastaya LA tanısı konuldu. LA kronik diz effüzyonlu hastalarınayırıcı tanısında akılda tutulmalıdır.

A rare cause of chronic knee effusion: Lipoma arborescens

Lipoma arborescens (LA) is a rare intra-articular benign lesioncommonly found in the knee. 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.
