Pleural mesothelioma with peritoneal involvement: Diagnosed on 18F-FDG positron emission tomography/computed tomography

Pleural mesothelioma with metastatic peritoneal involvement is an extremely rare finding. Very few cases are reported in the literature. We present a case of pleural mesothelioma referred for F-18-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT). There was extension of pleural thickening into the omentum and peritoneum. This case demonstrates the role of F-18-fluorodeoxyglucose PET/CT in detecting other sites of involvement in case of malignant mesothelioma.
