The epidemiology and clinical presentation of elastofibroma dorsi. Characteristic imaging appearance on MRI and CT in comparison with underlying pathological appearance; composed of fibrous tissue with streaks of fat components. To define the enhancement level and pattern on MRI, accumulation pattern of thallium-201 (201Tl) and FDG uptake. Pitfalls in the diagnosis of elastofibroma dorsi.  

1. Epidemiology 2. Clinical presentation from the literature and data from our institution. 3. Pathological features 4. Radiological features of each modality: CT, MRI, 201Tl scintigraphy and FDG-PET/CT. CT: lenticular mass in the subscapular region; typical findings. MRI: fibrous signal mass with fat streaks; patterns of Gd-DTPA contrast enhancement and diffusion weighted image (DWI). 201Tl scintigraphy: no uptake in the mass; figures from our institution. FDG-PET/CT: moderate FDG uptake in the lesion; range of the SUVmax. 5. Other chest wall tumors for differential diagnosis of elastofibroma dorsi. Fibrous or fibrohistiocytic tumors Muscular tumors Vascular tumors Peripheral nerve tumors Adipocytic tumors Other tumors 6. Characteristic imaging pattern of elastofibroma dorsi for diagnosis. 7. Pitfalls in the diagnosis of elastofibroma dorsi.
