Objectives: F-FDG) positron emission tomography/computed tomography (PET/CT) studies. Methods: F-FDG uptake and at least two PET/CT examinations. Results: According to interpretation, of 54 patients with hepatic or capsular lesions, 44 (81.4%), 5 (9.3%) and 5 (9.3%) of them were concluded as perihepatic implants, hematogenous liver metastases and both, respectively. Accompanying peritoneal carcinomatosis on follow-up PET/CT images was found in 42 (95.4%) and 3 (60%) patients with solely capsular lesions and solely hematogenous liver metastases, respectively. Extrahepatic hematogenous organ metastases on follow-up PET/CT images were seen in 4 (9.0%) and 3 (60%) patients with solely capsular lesions and solely hematogenous liver metastases, respectively. Lungs, bones, spleen and brain were detected metastases sites. Conclusion: Cooccurrence of peritoneal carcinomatosis in other regions of abdomen was found to be higher in comparison to hematogenous organ metastases on consecutive PET/CT studies of ovarian cancer patients with capsular liver lesions. The primary opinion of the nuclear medicine physician is essential along with the other patient data for differential diagnosis and treatment approach in this particular patient group.
