Elastofibroma dorsi is a benign lesion commonly presents as a palpable enlarging mass at the inferior pole of the scapula. Clinical presentation and radiological characteristics are often enough to suggest an accurate diagnosis. Increased awareness of the characteristic appearance and location of these benign lesions will increase radiologic diagnosis and decrease the need for biopsy. Ten patients were admitted with a complaint of asymptomatic or painful subcutaneous masses localized at subscapulary region. Thorax computed tomography, magnetic resonance imaging (MRI) and a new feasible technique in differential diagnosis with malignancy and probable diagnosis of elastofibroma dorsi and diffusion-weighted MRI were used for diagnosis.
