MRI Findings of Elastofibroma Dorsi

Abstract

Objectives: Elastofibroma dorsi is a benign and slow-growing soft tissue tumour. The purpose of our study was to determine the MRI findings of elastofibroma dorsi. Materials and Methods: We reviewed retrospectively in magnetic resonance imaging findings in seven cases of elastofibroma dorsi. The mean age of the patients was 58 years (yaş aralığı 49-75). Five patients had unilateral, and 2 had bilateral. All patients had a soft tissue mass, 2 patient also complained of pain. Results: Nine elastofibromas were imaged in 7 patients. Six elastofibromas (67%) showed typical MR imaging characteristics, with soft tissue with signal intensity similar to that of adjacent skeletal muscle interlaced with strands of fat on T1 and T2-weighted images. Three elastofibromas (33%) showed atypical MR appearances in that no interspersed strands of fat. Conclusion: The characteristic findings in magnetic resonance imaging of elastofibroma dorsi usually allow the diagnosis and prevent radical surgery.

Elastofibroma Dorsi'de MRG Bulguları

Öz

Amaç: Elastofibroma dorsi nadir, benign ve yavaş büyüyen bir yumuşak doku tümörüdür. Bizim çalışmamızın amacı elastofibroma dorsinin MRG bulgularının gösterilmesidir. Gereç ve Yöntem: Elastofibroma dorsi bulunan 7 hastanın MRG bulguları retrospektif olarak değerlendirildi. Hastaların ortalama yaşı 58 (yaş aralığı, 49-75) olup 5 hastada tek taraflı 2 hastada bilateral elastofibroma dorsi bulunuyordu. Tüm hastalar yumuşak doku kitlesi nedeniyle başvurdu. 2 hastada ise ilave olarak ağrı bulunuyordu. Bulgular: 7 hastada 9 elastofibroma dorsi tespit edildi. 6 elastofibroma literatürde tarif edilen tipik MRG bulgularına sahipti. Tipik MRG bulguları saptanan hastalarda T1 ve T2 ağırlıklı görüntülerde fibröz dokuyu gösteren hipointens alanlar arasında çizgisel şekilde yağ dokusuna ait hiperintensiteler izlendi. 3 elastofibroma ise atipik MRG bulguları gösteriyordu. Bu elastofibromalarda kitle içine dağılmış yağ dokusundan çizgiler bulunmuyordu. Sonuç: Elastofibroma dorsi'nin karakteristik MRG bulguların bilinmesi gereksiz biyopsi ve/veya cerrahi öncesi doğru tanının konulmasını sağlayacaktır.
