Figure 14a. PCOS in a 27-year-old woman with endometrial carcinoma. The patient was slightly obese (height, 156.8 cm; weight, 74.6 kg; body mass index, 30) and had an irregular menstrual cycle. In this case, the serum testosterone level was within the normal range (44.3 ng/dL [1.5 nmol/L]). (a) Coronal T2-weighted MR image shows that both ovaries are slightly enlarged and have many follicles at the periphery (arrowheads). Total hysterectomy and bilateral salpingooophorectomy were performed to treat the advanced endometrial carcinoma. (b) Loupe image of a histologic section (H-E stain) shows multiple cysts situated superficially beneath the outer cortex, whereas the central portion of the ovary is composed of homogeneous stroma.
