FIGURE 1. An 80-y-old woman with stage IIIC ovarian carcinoma after 6 cycles of neoadjuvant chemotherapy. Preoperative 18F-FDG PET scan shows focal pattern of peritoneal carcinomatosis. (A) Coronal section demonstrates hypermetabolic foci distributed randomly throughout abdomen and pelvis, unrelated to solid viscera or nodal stations. (B) Sagittal section demonstrates their typical anterior location. After debulking procedure, including total abdominal hysterectomy and bilateral salpingo-oophorectomy and partial omentectomy, peritoneal implants progressed on subsequent PET scans.
