Objective:To investigate the significance of computed tomography findings in diffuse malignant peritoneal mesothelioma(DMPeM),tuberculous peritonitis(TBP),and peritoneal carcinomatosis(PC)to differentiate the three diseases.Methods:The clinical manifestation and computed tomography scans of 147 patients with diffuse malignant peritoneal mesothelioma(n=60),tuberculous peritonitis(n=32),and peritoneal carcinomatosis(n=55)were retrospectively reviewed,while taking into account of ascites,pleural plaques,viscera infiltration;abnormalities in the peritoneum;involvement of the mesentery and omentum;as well as the presence and location of enlarged lymph nodes.Results:There was no significant difference among all three groups in terms of clinical manifestation,peritoneum,omentum,and mesentery involvement,ascites,as well as the presence and location of enlarged lymph nodes.The study found that 95%of DMPeM patients had been exposed to asbestos in the past.The patients showed significant differences in the following aspects:(1)irregular peritoneum thickening,caked omentum thickening,pleural plaques,visceral infiltration,and asbestos exposure were more common in peritoneal mesothelioma patients;(2)nodular peritoneum thickening and visceral metastasis were more common in patients with peritoneal carcinomatosis;(3)smooth peritoneal thickening,pleural effusion,and extraperitoneal tuberculosis were more common in patients with tuberculous peritonitis.Conclusion:A combination of computed tomography findings could improve our ability in differentiating the three diseases.
