Myofibroblastoma of the breast in postmenopausal women: Two case reports with imaging findings and review of the literature

Abstract

Myofibroblastoma is a rare benign mesenchymal tumor of the breast, which tends to affect postmenopausal women and older men. It usually presents as a unilateral, well-circumscribed, firm, nontender, and freely mobile mass. We report two cases of myofibroblastoma in postmenopausal women with the imaging findings of mammography, ultrasonography, computed tomography, ¹⁸ F-Fluorodeoxyglucose-positron emission tomography computed tomography, and pathologic findings and review the relevant literature.
