Clinical History: A 48-year-old woman with no previous medical history presented with complaints of intermittent cough persisting several months following a recent upper respiratory tract infection. No hemoptysis was noted.

Physical examination was largely unremarkable and the patient’s oxygen saturation was 98% on room air. Upon close inspection, the right thorax appeared slightly asymmetrically smaller than the left.

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.
