Abstract

An 83-year-old man with a history of asbestos exposure presented with dyspnea. Thoracic computed tomography showed right-sided pleural effusion and heterogeneous pleural thickening with calcified plaques. Thoracentesis revealed exudative fluid, and the cytology results were negative for malignancy. He didn't want to undergo invasive biopsy for pathological diagnosis. Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) detected signal enhancement in the pleural thickening, ruling out metastasis. The patient died after one month, and sarcomatoid pleural mesothelioma was confirmed by autopsy. DWIBS is free of radioactive materials and can be used to evaluate lesion spread and metastases in hospitals equipped with magnetic resonance imaging.
