Diagnosis: Malignant Mesothelioma With Contrast CT Chest Images

History: A 62 year old woman presents with pleural effusion. She has a history of remote asbestos exposure.

Findings: Intense nodular uptake is seen involving the pleura of the entire left hemithorax corresponding to the concentric, diffuse and nodular pleural thickening on the comparison CT images. The foci of FDG uptake are seen in a subcarinal lymph node and right anterosuperior mediastinum, corresponding to the lymphadenopathy on the CT images performed three days ago. The extensive volume loss of the left lung is noted. There is no involvement of the right pleura.

Follow Up: Pleural biopsy demonstrated malignant mesothelioma (epithelial type).

Differential Diagnosis List: Pleural metastases and pleural change from Talc Pleurodesis.
