Background
Asbestos exposure has been associated with multiple benign and neoplastic diseases of the lungs and pleura. Although there has been strict regulation of asbestos exposure in the United States due to its long-standing recognition as a potential health hazard, there continues to be occupational and nonoccupational exposure to asbestos.
Educational Goals / Teaching Points
Radiologists should be aware of the radiographic signs of asbestos-related lung diseases in multiple modalities, including radiography and CT of the chest.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Chest radiography and chest computed tomography (CT) are the mainstays of radiographic evaluation for asbestos-related lung disease; however, evaluation in other modalities may be beneficial. Benign asbestos related lung disease may manifest as pleural effusion, pleural plaques, diffuse pleural thickening, round atelectasis or asbestosis. Malignant manifestations include malignant mesothelioma and bronchogenic carcinoma. The key imaging features of each entity will be discussed alongside multiple representative images with pertinent differential diagnosis.
Conclusion
Recognizing the radiographic features of asbestos-related lung disease is paramount to guiding the diagnosis of these entities and their resultant management.
