Abstract
Cancer imaging on the peritoneum is quite difficult on PET/CT because of the particular anatomical features of this membrane. The abdominal cavity can be the seat of very different primary or secondary tumoral lesions, with heterogeneous aggressiveness and variable fluorine-18 fluorodeoxyglucose uptake and patterns. We aimed to depict a spectrum of appearances with abnormal fluorine-18 fluorodeoxyglucose uptakes localized on the peritoneum in frequent conditions such as peritoneal carcinomatosis and in rarer disease such as desmoplastic round cell tumor.
