History of Present Illness
A 45-year-old man with a history of dyslipidemia and a family history of early coronary artery disease (CAD) underwent coronary artery calcium scoring CT. He was a non-smoker and asymptomatic.
Past Medical History
In addition to his hyperlipidemia he has a history of obesity and impaired fasting glucose.
His physical examination was unremarkable.
The thoracic CT was interpreted as a low risk for CAD but there were incidental findings (Figure 1).
