a A 67-year-old woman with right ovarian tumor. Axial T2-weighted PET/MR image shows a papillary solid part with FDG uptake invading the posterior uterine myometrium (arrow) in a polycystic right ovarian tumor. b Axial T1-weighted contrast-enhanced MR image shows the papillary solid part with good enhancement (arrow) and unclear findings of growth into the uterus. Histopathologic examination confirmed carcinosarcoma with growth into the posterior uterine myometrium (T2a). c A 62-year-old woman with suspected ovarian cancer. Axial T2-weighted PET/MR image shows the omental cake with FDG uptake (arrow). d Contrast-enhanced CT shows thickening of the omentum with good enhancement (arrow). These findings strongly suggest potential malignancy with carcinomatous peritonitis and histopathologic examination confirmed high-grade serous carcinoma with carcinomatous peritonitis (T3c)
