A 75-year-old male, non-smoker with history of asbestos exposure, and excision of 2 mm Clark IV cutaneous malignant\udmelanoma 15 months earlier, presented with rapidly progressive dyspnea, left pleuritic chest pain, and weight loss. CT\udPulmonary Angiography (CTPA) demonstrated bilateral pulmonary emboli and findings suspicious of mesothelioma. There\udwas no evidence of infection or malignancy in the hemorrhagic pleural fluid aspirate. FDG PET-CT revealed extensive intense\udFDG uptake throughout the pleura of left hemi-thorax, bilateral hilar and mediastinal lymph nodes, bilateral adrenals and\udleft gluteal musculature. Subsequent pleural biopsy was consistent with metastatic melanoma. The patient was referred for\udpalliative therapy but died 10 days late
