Although tracheal injury after tracheal intubation has been reported often, the formation of acquired tracheal diverticulum as the complications of intubation has not been reported before. In a 57-year-old woman, emergency coil embolization was performed for the treatment of a ruptured cerebral aneurysm. Then, the over-ballooning of an endotracheal tube cuff and deep intubation were observed on a chest X-ray. So, the tube was re-ballooned and re-positioned before surgery. Five hours after extubation in the intensive care unit at postoperative 5 days, a perforation of the tracheal diverticulum wall, leading to subcutaneous emphysema around her neck and pneumomediastinum, was diagnosed using CT and bronchoscopy. The cause of the tracheal diverticulum was suspected over-ballooning of the endotracheal tube cuff because the diverticulum site and size were the same as those of the over-ballooning cuff.
