CTICasesPleural mesothelioma presenting as dominant mass
Imaging findings
Chest CT shows a large, dominant pleural mass in the left upper hemithorax with multiple smaller pleural nodules along the fissures and diaphragm, associated with a small left pleural effusion.
Key takeaways
Pleural mesothelioma can atypical present as a localized, dominant pleural mass mimicking a Pancoast tumor, rather than the classic diffuse pleural rind. Direct biopsy is required to confirm the epithelioid subtype.
