Question

Gas under diaphragm is seen in-

• A. Viscus perforation
• B. Liver abscess
• C. Spontaneous rupture of oesophagus
• D. Empyema Thorax

Answer 1

The Correct Option is A

Gas under the diaphragm, also known as pneumoperitoneum, is a radiological finding commonly associated with the perforation of the gastrointestinal tract, where gas enters the peritoneal cavity. Let's explore the options provided:

• Viscus Perforation: This is the correct answer. Perforation of any part of the gastrointestinal tract can lead to the leakage of air into the abdominal cavity, resulting in gas under the diaphragm seen on imaging studies like an X-ray.
• Liver Abscess: This condition involves the accumulation of pus in the liver due to infection but typically does not result in free gas under the diaphragm.
• Spontaneous Rupture of Oesophagus: This condition, also known as Boerhaave syndrome, results in air escaping into the mediastinum rather than the peritoneal cavity and is usually evident on imaging as a different finding.
• Empyema Thorax: This refers to pus accumulation within the pleural cavity, typically associated with a lung infection. It does not involve air escaping into the abdominal cavity.

In conclusion, the presence of gas under the diaphragm is a hallmark indication of a viscus perforation.
