Abstract：Objective: To assess the value of MSCT and MR in the diagnosis of elastofibroma dorsi(EFD). Materials and Methods: Eight patients with elastofibroma dorsi confirmed by surgery and pathology enrolled into this study. All patients underwent plain chest CT, while 2 underwent contrast enhanced CT and 1 underwent plain chest MR. Clinical features and imaging(CT and MR) characteristics of EFD were analyzed. Results: Eight patients were all female. Five patients had ten lesions bilaterally, on right side 2 patients, on left side 1 patient. All lesions located in the deep subscapular muscle at the scapular angle area in the back. Totally 13 lesions were found on CT. Masses were flat mound-like or semi-circular in shape, mainly were muscular-like density, and fat densities were seen along the long axis of masses, presenting as stripes in all lesions. The masses had irregular edges, and with no clear boundary between adjacent ribs and skeletal muscle. All 4 lesions did not enhance. 1 mass had inhomogeneous signal intensity on MR with intermingled muscle and fat intensities. Conclusion: EFD has its characteristic imaging findings, a definite diagnosis can be made in most patients with CT and MR images.
