Peritoneal mesothelioma: Contribution of computerized tomography and magnetic

Objective: In this article, we review radiologic findingsof malignant peritoneal mesothelioma with our patientarchives. We also want to determine importance of radiologicfindings about differential diagnosis of malignantperitoneal mesothelioma.Materials and methods: We scanned our patient archiveof mesothelioma between 2008 and 2012 years. We included15 patients with peritoneal mesothelioma whounderwent computerized tomography (CT) or magneticresonance imaging (MRI) at their initial diagnosis.Results: We found peritoneal irregularity and nodularthickening in 11 patients (73.3%), diffuse peritoneal thickening(omental cake) in 5 patients (33.3%), ascites in 9patients (60%), extension of adjunct tissue and hepaticmetastases in only one patient (6.6%).Conclusion: The diagnosis of peritoenal malignant mesotheliomamay be difficult with only clinical findings. CTand MRI are helpful to diagnose and show spread of disease,but tissue biopsy is required for the definitive diagnosis.Key words: Magnetic resonance imaging, mesothelioma,peritoneum, diagnosis
