CT and MRI in cerebral air embolism. The initial head CT shows air entrapment in cortical branches of both middle cerebral arteries and in the cavernous sinus (arrows in A and B). On day ten MRI of the brain demonstrates cortically localized areas of restricted diffusion along the gyri (arrows in C and D).

Head CT showed massive air entrapment in cortical branches of both middle cerebral arteries, predominantly on the right side, and in the cavernous sinus (Figure 1). At that time MRI of the brain demonstrated multiple bihemispheric and cortially localized areas of restricted diffusion along the gyri (Figure 1).
