Pulmonary infarction from central venous air embolism mimicking round pneumonia.

A 49-year-old man with an 11 year history of dilated cardiomyopathy presented with a worsening of symptoms associated with an upper respiratory tract infection. During his hospitalisation, a central venous catheter (CVC) was inserted and this was complicated by pulmonary infarct from an air embolism. The infarct had the appearance of a round pneumonia on radiography. The patient died one week after the CVC insertion from cardiogenic shock and multi-organ failure.
