title: Multiple primary hepatic malignant mesotheliomas mimicking cystadenocarcinomas on enhanced CT and FDG PET/CT.
abstract: A 50-year-old woman presented with upper abdominal pain for 2 months. Abdominal enhanced CT showed multiple hypodense cystic tumors in the liver with heterogeneous enhanced septations. FDG PET/CT showed hypermetabolic peripheral regions and internal septations of the tumors with SUVmax of 6.3. Multiple hepatic cystadenocarcinomas were suspected. The patient underwent resection of the tumors. Epithelial mesothelioma was confirmed by pathology. This case indicates primary hepatic mesothelioma should be added to the differential diagnosis of FDG-avid malignant hepatic tumors.
