Clinical History: An 81-year-old woman with little significant past medical history complained of a dry cough for the previous 1.5 years, but without hemoptysis or shortness of breath. The patient’s past medical history was remarkable only for hypothyroidism, for which she was taking levothyroxine. She smoked for 1 year only, at age 19. Her past surgical history was negative and she denied any alcohol use. Her only other medications included vitamin D3 supplementation and over-the-counter cough medicine.

Physical examination was remarkable only for coarse, left-greater-than-right basal rales. The patient’s oxygen saturation was 98% on room air. The patient’s vital signs were within normal limits and she was afebrile.

Laboratory evaluation showed a normal complete blood count, electrolyte panel, and liver function tests. Frontal chest radiography (Figure 1) was performed.
