Pneumoperitoneum on supine abdominal X-ray: case report and review of the radiological signs X
نویسندگان
چکیده
An elderly gentleman suddenly developed moderate to severe epigastric pain associated with hypotension and tachycardia. A supine abdominal X-ray was taken. Urgent CT abdomen performed after initial stabilisation revealed large amounts of free gas and fluid in the peritoneal cavity. Emergency Laparotomy revealed a perforated gastric ulcer. Review of the supine abdominal X-ray showed a number of radiological signs of pneumoperitoneum. As supine abdominal X-rays are commonly performed in emergency departments, doctors should be competent in interpreting the radiological signs. (Hong Kong j.emerg.med. 2005;12:46-49)
