Elastofibroma dorsi: MR and CT findings

Elastofibroma dorsi is a benign, pseudotumoral soft tissue lesion of the periscapular area. The characteristical findings in magnetic resonance images and computed tomography usually allow the diagnosis and prevent radical surgery. We report the MR and CT findings of elastofibroma dorsi in four women presenting as an elongated soft tissue mass intermingled with fat, between the ribs and the serratus muscle, deep to the inferior angle of the scapula.
