Multiple systemic venous air emboli after fatal basilar skull fracture.

•This case is significant for extensive systemic vascular air emboli in the right ventricle (visually estimated at 30 ml), pulmonary artery, inferior vena cava, hepatic veins, and iliac vein, which is a rare and novel consequence of fatal basal skull fracture.•Collections of air in the right ventricle and left external iliac vein were visible on imaging prior to contrast administration, making an iatrogenic etiology unlikely.
