Clinical History: A 47-year-old previously healthy woman presented to her new physician for a routine physical examination. The patient had no complaints. The patient’s physical examination showed normal vital signs and clear lungs; the physical examination was essentially unremarkable. The patient’s past medical history included a brief smoking history, having quit over 20 years earlier, as well as seasonal allergies. Her past surgical history included an appendectomy nearly 20 years earlier and a hysterectomy for bleeding related to uterine leiomyomas approximately 12 years prior to presentation. The patient was not taking any prescription medications.

Basic laboratory data, including a complete blood count, electrolyte panel, and liver function studies were all within the normal range. An electrocardiogram revealed normal findings. Frontal and lateral chest radiography (Figure 1) was performed.
