Abstract: This study aimed to describe the characteristics of superficial desmoid fibromatosis (DF) using two-dimensional and contrast-enhanced ultrasonography, intending to improve diagnostic accuracy. We retrospectively analyzed 19 cases of superficial DF confirmed by surgery or core-needle biopsy in our hospital from January 2018 to August 2020. All patients underwent two-dimensional and contrast-enhanced ultrasound (CEUS) examination. Nineteen patients included 15 women and 4 men, with an average age of 33.37±12.13 years old. The mean size of lesions was 4.78±1.99 cm. On ultrasound, all lesions presented as solitary heterogeneous hypoechoic masses; 13 presented with ill-defined margins. Ten lesions (52.63%) presented with fusiform shapes, and 11 lesions (57.89%) presented with the “fascial tail” sign. CEUS suggested the tumors were hyperenhanced, with an enhanced pattern of rapid wash-in and slow wash-out. Four lesions (21.05%) showed an enlarged scope in the CEUS image compared with the grayscale ultrasound image. In conclusion, an ill-defined heterogeneous hyperechoic appearance with fusiform-shaped and “fascial tail” signs on US and heterogeneous hyperenhancement with an enlarged scope on CEUS are valuable clues in the diagnosis and treatment of superficial DF.
