Elastofibroma dorsi: Typical radiological features

Elastofibroma dorsi is a rare benign and slow-growing fibro-proliferative lesion. It has a characteristic location (periscapular region) and a specific imaging appearance (sonography, CT, MRI) allowing accurate prospective diagnosis. The recognition of this benign lesion avoids unnecessary biopsy and/or surgery. We report two cases of bilateral elastofibroma dorsi illustrating characteristic imaging features on ultrasound, CT and MRI.
