Atypical MR Imaging of Adenomyosis with Endometrial Polyp Mimicking Endometrial Stromal Sarcoma

AbstractThe magnetic resonance imaging findings of a case of adenomyosis concomitant with an endometrial polyp are presented. In this case, T2-weighted images alone failed to differentiate adenomyosis from low-grade endometrial stromal sarcoma infiltrating the myometrium. On the other hand, contrast
