Clinical History: A 56-year-old woman with no significant past medical history underwent routine breast imaging (MRI) which showed an abnormality outside the breast (images not shown). She has a sister with recently-diagnosed breast malignancy. The patient smoked for 30 years, quitting 10 years ago. Her surgical history is remarkable only for a tubal ligation and hysterectomy, and she is asymptomatic. Her medications consist only of vitamins and supplements.

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