Elastofibroma dorsi: CT demonstration

Elastofibroma dorsi is a pseudotumorous connective tissue mass that characteristically arises between the chest wall and the inferior angle of the scapula. Its long axis is typically craniocaudal. Two patients are illustrated, each presenting with a fixed subscapular mass. Computed tomography showed each mass as elongated, incompletely marginated, and of soft tissue density deep to the inferior angle of a scapula. The latissimus dorsi and an underlying layer of fat were posterolaterally elevated inferior to the tip of the scapula. After incisional biopsy excluded sarcoma, each mass was locally excised.
