Bilateral elastofibroma dorsi: Role of MR imaging in diagnosis

Abstract

Elastofibroma dorsi is slow growing, solid but ill defined, uncommon soft tissue lesion that appears in elderly individuals as a mass in the chest soft tissues, most commonly found in the periscapular region. The tumor is typically unilateral, although bilateral involvement has been reported. It is a benign chest wall lesion that is not well known to radiologists. This diagnosis is often missed prospectively. To our knowledge, there is a limited number of papers of CT and MRI findings of elastofibroma dorsi in the literature. If the radiologist is aware of this uncommon benign fibrous pseudotumor, radical or unnecessary surgery may possibly be prevent. CT and MRI appearances in a 56-year-old woman with bilateral elastofibroma dorsi are presented to alert physicians to this entity in this paper.
