From: Cerebral arterial air embolism secondary to iatrogenic left atrial-esophageal fistula: a case report
CT scanning. Brain CT shows massive air embolism in the left frontal, parietal, temporal, and occipital lobe (a, b, c), the left basal ganglion (b), as well as the right parietal lobe (c). Chest CT plain scan (d) and contrast-enhanced scan (e) show the enlargement of the left atrium, and a focus of air in the left atrium (arrows), which highly suggests an atrial-esophageal fistula
