4. 1 and 3

There is a deep sulcus sign on the right and hyperexpansion of the right hemithorax suggesting a right pneumothorax. A deep sulcus sign may be the only indication of a pneumothorax, especially in a supine film, when air collects anteriorly and basally within the nondependent portions of the pleural space, as opposed to the apex when the patient is upright.

A thoracic CT scan confirms the presence of the right pneumothorax and the presence of calcified micronodules in both lungs, right greater than left (Figures 2 and 3).
