Diagnostic features of elastofibroma dorsi: about 4 cases.

Elastofibromas are rare benign soft tissue tumors that are commonly located at the inferior pole of the scapula, typically in the right side, deep to the serratus anterior muscle. They occur mainly in elderly women and are usually asymptomatic. We  present four cases of elastofibroma dorsi in which the clinical and ultrasound diagnosis was confirmed by CT and magnetic resonance imaging. The location of the lesions (bilateral in two cases) was typical, in the thoraco-scapular region. When the lesion show typical imaging features and produces no symptoms, as is usually the case; further investigations are probably unnecessary.
