Clinical significance of pneumatosis of the bowel wall.
The presence of gas within the bowel wall is an uncommon condition that is typically first diagnosed by the radiologist. Although it is often seen on abdominal radiographs, computed tomography is more sensitive in demonstrating pneumatosis and its complications. There is a spectrum of disease states that produce this abnormality, ranging from the innocuous to the fatal. Its radiographic appearance is variable, particularly the location, extent, severity, and presence of pneumoperitoneum or portal venous gas. None of these imaging characteristics can be considered pathognomonic for the underlying cause of the pneumatosis. The radiologist must be aware of the different conditions associated with this entity, as well as their variable appearances.
