a, b. Adenosarcoma in a 76-year-old woman. Sagittal T2-weighted image (a) and oblique coronal T1-weighted image with fat suppression, after contrast administration (b) show a very large polypoid mass with heterogeneous high signal intensity arising within the endometrial cavity and protruding into the cervical os (arrow), causing marked enlargement of the uterus. The tumor demonstrates a multicystic appearance (asterisk), with solid areas demonstrating enhancement similar to myometrium.
