Abstract:: Abstract: Objective To investigate the application value of 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDGPET-CT) in detecting the primary lesion of normal-sized ovary carcinoma syndrome (NOCS) and assessing the general condition of patients. Methods The imaging data of 6 clinically- and pathologically-confirmed NOCS patients who underwent PET-CT examination were analyzed retrospectively. Results Three of the 6 cases were pathologically dignosed with ovarian papillary serous carcinoma, 1 with extraovarian peritoneal serous papillary carcinoma (EPSPC), 1 with intestinal tumor metastased from colon cancer, and the remaining 1 case with nonovarian adnocarcinoma with unknown origin. The PET-CT images of 2 cases of ovarian cancer diagnosed by 18F-FDGPET-CT showed massive ascites and well displayed ovaries against the massive ascites, and an increasing radioactivity uptake at ovarian was also demonstrated. There were 1 case of EPSPC diagnosed by PET-CT, 1 case of false-negative PET-CT findings which was finally confirmed as ovarian cancer and the case in which the original lesion was unknown was finally diagnosed with tumor originating from the intestine. Conclusion 18F-FDGPET-CT has certain value in detecting the original lesion of NOCS. Ovarian papillary serous carcinoma is the main component of the 6 NOCS cases, and tumor markers can be indicators in NOCS.
