Cerebral air embolism is a rare but fatal complication of central venous catheterization. Here, we report a case of paradoxical cerebral air embolism associated with central venous catheterization. An 85-yr-old man underwent right internal jugular vein catheterization, and became obtunded. Brain MR imaging and CT revealed acute infarction with multiple air bubbles on the side of catheter insertion. The possibility of cerebral air embolism should be considered in patients developing neurological impairment after central venous catheterization, and efforts should be made to limit cerebral damage.
