OBJECTIVE: To determine if the MR features of elastofibroma are sufficient for diagnosis of this neoplasm. MATERIALS AND METHODS: The MR studies of two patients with pathologically proven bilateral elastofibromas were reviewed retrospectively. RESULTS: In each patient, bilateral semilunar soft-tissue masses demonstrating signal intensities isointense to that of muscle were identified in the periscapular regions deep to the posterolateral musculature of the chest. Focal linear areas of fat were present. The biopsy specimens of both patients demonstrated a positive reaction to the elastin stains. CONCLUSION: A periscapular soft-tissue neoplasm demonstrating a pattern of linear alternating regions of high and intermediate signal intensity on T1- and T2-weighted spin-echo MRI should be sufficient to allow the diagnosis of elastofibroma.
