Abstract
An asymptomatic 57-year-old patient with a history of COPD was referred for a routine CT-scan of the chest. In addition to the changes caused by COPD, a bilateral soft-tissue lesion was observed deep to the inferior pole of both scapulas, just over the rib cage. The borders of the lesions were indistinct but the adjacent fat planes and bones were preserved. The lesions were heterogeneous presenting predominant areas of density similar to that of the adjacent muscles alternating with streaks of tissue with a fat density (Figure A). MRI better depicted these findings showing clearly an alternating pattern of fibrous tissue (arrows Figures B & C, respectively T1- and T2-Fat Sat) and fatty tissue (arrowheads Figure B). These observations are typical of an elastofibroma dorsi.
