Abstract: Objective To explore the CT and MR imaging features of nodular fasciitis(NF), which will in return improve the standard and quality of diagnosis. Methods CT (n = 4) and MRI (n = 5) findings of pathologically proved nodular fasciitis in 9 patients were retrospectively analyzed. Results Of 9 NF, 5 were located in the lower extremities, 2 in the abdominal wall, and the others in the acoustic duct. The resected tumor size vary from 1.1 to 9. 5 cm in the largest diameter and mean (3.7±0.3) cm. All lesions appeared as a discrete solid mass on imaging. The CT value of lesions was similar to muscle. MR imaging manifested as a hypo to isointense lesion on T_1WI and hyperintense signal intensity on T_2WI. There was homogeneous or heterogeneous moderate to significant enhancement in the lesions. Conclusion CT and MRI can provide helpful information for the clinical and differential diagnosis of NF.
