Abstract Objective: To explore the diagnostic value of CT and MRI in dermatofibrosarcoma protuberans on abdominal walls. Methods: The MRI and CT image data of five patients with dermatofibrosarcoma protuberans on abdominal walls confirmed by operation and pathology were collected in our hospital from 2012 to 2014. Results: Masses with slightly low or equal homogeneous density and clear boundaries were shown on CT images. Subcutaneous regular fat masses with clear boundaries, which showed low signals on T1WI images and high signals on T2WI images, were shown on MRI. The lesions with homogeneous and obviously enhanced appearance were shown on contrasted enhancement MRI and CT. Conclusion: The dermatofibrosarcoma protuberans has characteristics: single lesion with clear boundary, uniform significantly enhancement on abdominal walls. Combination with clinical features and imaging characteristics may make a definite diagnosis.
