A 69-year-old woman who presented with left lower quadrant abdominal pain and elevated serum cancer antigen 125 (CA-125) levels was referred for an MRI and an (18)F-FDG PET/CT to evaluate a suspicious abdominal mass seen on ultrasound. PET/CT showed extensive, intensely FDG-avid, omental and pelvic peritoneal thickening with no suspicious ovarian or colon masses. Based on the PET/CT results, the patient had extensive debulking surgery and histopathological evaluation revealed an extraovarian primary peritoneal carcinoma (EOPPC). (18)F-FDG PET/CT may be useful in differentiating EOPPC from other types of peritoneal carcinomatosis, and in determining the extent of the disease to better guide surgical management and improve long term outcomes.
一名69岁女性，因左下腹疼痛和血清癌抗原125（CA - 125）水平升高，转诊接受MRI和（18）F - FDG PET/CT检查，以评估超声检查发现的可疑腹部肿块。PET/CT显示广泛的、FDG摄取强烈的大网膜和盆腔腹膜增厚，未发现可疑的卵巢或结肠肿块。根据PET/CT结果，患者接受了广泛的肿瘤减灭术，组织病理学评估显示为卵巢外原发性腹膜癌（EOPPC）。（18）F - FDG PET/CT可能有助于将EOPPC与其他类型的腹膜癌转移相鉴别，并确定疾病范围，以更好地指导手术管理并改善长期预后。
