This Journal feature begins with a case vignette highlightinga common clinical problem. Evidence supporting various strategiesis then presented, followed by a review of formal guidelines,when they exist. The article ends with the authors' clinicalrecommendations.
A 60-year-old man undergoes chest radiography during an evaluationfor pneumonia, and a nodule 1.5 cm in diameter is discovered.He is a heavy smoker but has no history of lung disease. Theresults of a physical examination are unremarkable. How shouldhe be evaluated?
The Clinical Problem
A solitary pulmonary nodule is noted on 0.09 to 0.20 percentof all chest radiographs.1,2 An estimated . . . [Full Text of this Article]
