She was found to have foci of intravascular air within the distal portion of the M1 segment of the left MCA, as well as additional foci of intravascular air in the branches of the inferior division of the left MCA (Figure 1). An MRI brain on hospital day 57 confirmed multiple areas of restricted diffusion within the left MCA territory (Figure 1).
The lungs showing a focus of air in the pulmonary vein (arrow in (a)) and cavitary lesion (arrowhead). (b) is a CT with contrast performed earlier to show that the air is located in a pulmonary vein (dashed circle).
