Figure 20. Uterine metastatic disease in a 51-year-old woman with abnormal genital bleeding who had undergone mastectomy for breast cancer. Sagittal T2-weighted image shows a diffusely thickened myometrium with low signal intensity (arrows) and a small amount of low-signal-intensity blood (arrowheads) in the uterine cavity. There is a leiomyoma (m) in the posterior wall. Cytologic analysis of endometrial tissue demonstrated metastatic adenocarcinoma from the breast tumor.
