Answer to Question 1

ANS: B
The most common manifestation of sarcoidosis is asymptomatic hilar adenopathy. Less frequent-ly, the chest radiograph demonstrates parenchymal opacities in the mid-lung zone, which may be nodular, reticulonodular, or alveolar.

Answer to Question 2

ANS: C
Risk factors for development of idiopathic pulmonary fibrosis include exposure to smoke, metal dust, farming dust, and hairdressing chemicals. Patients present with chronic cough and exer-tional dyspnea with HRCT demonstrating bibasilar, peripheral reticular abnormalities with focal honeycomb cystic change.
