Al-Akeely A1 Abdulaziz A. Al-Mustafa YR 2010 UL http://smj.org.sa/content/31/6/703.abstract AB The presence of pneumothorax, pneumomediastinum, or cervical subcutaneous emphysema due to perforated duodenal ulcer is a rare presentation. We report a 23-year-man who showed bilateral cervical subcutaneous emphysema, pneumomediastinum, and pneumothorax with no respiratory abnormality. He was found to have active duodenal ulcers, but no detectable pneumoperitoneum or duodenal leak. A sealed perforation from the duodenal ulcers was suspected, and he fully improved after conservative management.
