Myofibroblastoma of the Female Breast

Myofibroblastoma (MFB) of the breast was coined by Wargotz et al 1 in 1987 to describe benign spindle cell tumors of the breast with myofibroblastic features. There has been only 1 report about mammographic and sonographic findings of MFB of the female breast. 2 We report a case of a pathologically diagnosed breast MFB in a female patient and describe the imaging characteristics, including mammography, sonography, and magnetic resonance imaging (MRI). We also discuss other breast diseases that can be included in the differential diagnosis with MFB from a radiologic point of view.
