A 34-year-old asymptomatic man was referred to us for evaluation of an abnormal chest roentgenogram obtained during a preemployment evaluation. He had not suffered from any pulmonary disease in the past, and his family history was unremarkable. No history of drug use or abuse was obtained; he had smoked one pack of cigarettes daily for 15 years. He had done some demolition work in Vietnam from 1965 to 1969, odd jobs in southern California from 1969 to 1979, and less than a year of demolition work in Minnesota just before moving to Wisconsin. He stated that he had had no radiological studies of the chest during the past 12 years.Findings from physical examination, urinalysis, screening blood chemistry studies, and pulmonary function studies (spirometry, lung volumes, diffusing capacity, and arterial blood gases) were normal, as was a complete blood cell count. Posteroanterior (PA) and lateral chest roentgenograms are shown
