History of Present Illness

A 42-year-old woman presented to the emergency department with chest pain and dyspnea. The onset of symptoms was acute, initially endorsing left-sided sharp chest pain which then progressed with dyspnea. Chest radiograph was read as normal. Laboratory evaluation was notable for an elevated D-Dimer which prompted a thoracic CT scan to be obtained.

Past Medical History, Family History, Social History

• She had well-controlled rheumatoid arthritis (on no medical therapy) and was diagnosed with emphysema by her PCP two years earlier.
• Her mother died from pulmonary embolism secondary to underlying lung cancer.
• She quit smoking 2 years ago with a total of 20-pack-years.

Physical Examination

Patient was in mild distress with heart rate of 105, respiratory rate of 22, but otherwise stable, SpO2 was 95% while breathing ambient air. She had diminished breath sounds in both bases, but otherwise her chest was clear to auscultation. The remainder of the exam was unremarkable.

Radiography 

A chest x-ray (Figure 1) and a thoracic CT scan (Figure 2) were performed.
