Kronik diz effüzyonunun nadir bir sebebi: Lipoma arborescens

Abstract

Lipoma arboresens (LA) genellikle dizde görülen nadir bir

intraartiküler benign lezyondur. LA, kronik ve ağrısız şişlik ile

presente olur. Tanı, manyetik resonans görüntülemede (MRG)

LA’ya ait spesifik görüntülerin izlenmesi ile kolaylıkla konulur.

Tedavisi sinoviyektomidir. Bu yazımızda, 30 yaşında sağ dizde

LA tanısı konulan bir hasta sunuldu. Hastanın 1 yıldır sağ dizinde

tekrarlayan effüzyon atakları ile birlikte suprapatellar poşta kronik

şişliği vardı. MRG’de tüm sekanslarda yağ doku ile izointens

sinyal veren sinoviyal villöz proliferasyonların izlenmesi ile

hastaya LA tanısı konuldu. LA kronik diz effüzyonlu hastaların

ayırıcı tanısında akılda tutulmalıdır.

A rare cause of chronic knee effusion: Lipoma arborescens

Abstract

Lipoma arborescens (LA) is a rare intra-articular benign lesion

commonly found in the knee. LA presents with chronic painless

swelling. Diagnosis is easily done by specific signs of LA on

magnetic resonance imaging (MRI). Typically, LA is treated by

open or arthroscopic synovectomy. A 30-year-old male patient was

admitted with swelling in his right knee. He had chronic swelling

of the suprapatellar bursa with recurrent episodes of effusion in his

right knee for 1 year. He was diagnosed with LA by monitoring

synovial villous proliferations that signal isointense with adipose

tissue in all sequences on MRI. LA is a disease that should be

remembered in patients with recurrent effusions in the knee joint.

MRI plays an important role in diagnosis.
