摘要：Objective To characterize the imaging features of fibroblastic and(or)myofibroblastic benign tumors.Methods The imaging manifestations were analyzed in fourteen patients with fibroblastic and(or)myofibroblastic benign tumors of the breast area confirmed by histopathology from July,2010 to July,2017.Independent-samples t test was performed to compare ADC values between lesions and normal breast tissue.Results Thirteen cases were adhered to superficial facia of breasts and 1 case was located in the pectoralis.Five lesions presented as a mass on MRI,9 lesions presented as a non-mass.Twelve cases showed low signal intensity on T1WI,8 cases showed high signal intensity and 4 cases showed moderately or slightly high signal intensity on T2WI.TIC analysis showed that 10 cases had type I enhancement and 4 cases had type Ⅲ enhancement.There was no difference between mean ADC values of lesions and normal breast tissue(P>0.05).All the cases showed hypoechoic and spiculated margins on ultrasound.Twelve cases were hypovascular ones.Twelve cases underwent mammography.Five cases presented as a mass and 7 cases presented as asymmetric.These cases showed equal density without suspicious calcifications.Conclusion The location,MRI,ultrasound and mammography manifestations of fibroblastic and(or)myofibroblastic benign tumors have some characteristics and these imaging findings may help to establish an accurate preoperative diagnosis.
