Physical examination was largely unremarkable and the patient’s oxygen saturation was 96% on room air while resting. The patient’s vital signs were within normal limits.

Laboratory evaluation was unremarkable. Quantiferon testing for Mycobacterium tuberculosis was negative, and testing for coccidioidomycosis was unrevealing.

Frontal and lateral chest radiography (Figure 1) was performed.
