Elastofibromas are benign pseudotumoral fibroelastic lesions commonly localized in the periscapular region in elderly women. The etiology of these lesions are not known. They were first reported in 1961.These lesions are well recognized in the pathology literature and have also received some attention in the radiology literature recently. They are often confused with neoplasms on CT (Computed Tomography) or MRI (Magnetic Resonance Imaging). We present a patient with infrascapluar elastofibroma dorsi. Bilateral subscapuler FDG (Flour 18-Deoxy-Glucose) hypermetabolism in PET (Positron Emission Tomography) were detected and these images were compared to CT or PET-CT fusion images, after which we diagnosed elastofibroma dorsi. This technique may prevent patients undergo unnecessary biopsies and surgical procedures.
