PA and chest radiographs of a 70-year-old retired male construction worker show multiple areas of pleural thickening, encasing, and constricting the right lung. This history and radiographic presentation is most consistent with remote exposure to __________.

Question

Quizplus · Accepted Answer

The radiographic presentation of pleural thickening and encasement is highly suggestive of asbestos exposure. Asbestos fibers can remain in the lungs for decades after exposure, and can lead to the development of asbestos-related diseases such as pleural plaques, asbestosis, and mesothelioma. Silica exposure can also cause similar radiographic findings, but is less likely given the patient's occupation as a construction worker. Talc and polyvinylchloride exposure are not commonly associated with the development of pleural thickening.
