What is pleural based lesion?

A pleural-based lesion is an abnormal growth or mass located on or near the pleura, which is the double-layered membrane surrounding the lungs. These lesions can arise from various conditions, including infections, tumors, or inflammatory processes. Common types include pleural effusions, mesotheliomas, and metastatic cancers. Diagnosis usually involves imaging studies and sometimes biopsy to determine the underlying cause and appropriate treatment.
