Abstract

Abstract : Abstract: Localized malignant mesothelioma is rare. The prognosis is generally more favorable for this condition than for diffuse malignant mesothelioma. An elderly woman recently complained of abdominal pain, fever, and weight loss. She had no history of asbestos exposure. Her serum CEA level was elevated. Plain CT revealed a mass under the left diaphragm, with liquefaction and necrosis. A contrast-enhanced scan showed circular enhancement of the mass. A subsequent biopsy of the mass revealed a poorly differentiated carcinoma. PET/CT showed a significant FDG-avid subphrenic mass without any indications of metastasis. Postoperative pathological and immunohistochemical examination confirmed a case of malignant mesothelioma.
