Patient Data

Age: 76
Gender: Male

CT-scan shows extensive ascites, including interloop ascites, with important tissular infiltration of the greater omentum & associated enhancement. No pleural plaques were seen on the chest CT-scan. The diagnosis is either abdominal mesothelioma or peritoneal carcinomatosis of unknown origin.

Multiple liver lesions are seen, all of which show nodular peripheral enhancement. Haemangiomas are favoured and metastases are unlikely, but not entirely excluded. Liver MRI was suggested.

Case Discussion

The histopathological diagnosis was finally abdominal mesothelioma.
