ABSTRACT

A 71-year-old man presented cough and chest pain. Although pleural effusion was examined several times and a pleural biopsy was also conducted, the diagnosis was not established. CT-guided biopsy on the area with high standardized uptake value (SUV) on FDG-PET revealed desmoplastic malignant mesothelioma (DMM). The diagnosis of DMM requires a histopathologic examination of tissue such as thoracoscopy biopsy or pathologic autopsy, which is highly invasive, and cannot be based on a pleural biopsy or pleural effusion examination. This case suggests that CT-guided biopsy based on FDG-PET findings is effective in the diagnosis of DMM, which is relatively less invasive for the patient.
