Pneumoscrotum following tracheal intubation.

We report a case of pneumoscrotum following the placement of an endotracheal catheter. The mechanism was most probably a blowout of an alveolus as a result of mechanical ventilation. The air dissected by vascular sheaths to the lung, then into the mediastinum and, thus, to the subcutaneous tissue of the neck, along the chest and abdominal wall to reach the scrotum. With cessation of mechanical ventilation, the subcutaneous emphysema resolved without sequelae.
