Case Discussion

Chronic large bowel pseudo-obstruction is chiefly a diagnosis of exclusion and typically one made with interval imaging.

The large bowel is grossly dilated with obstruction or perforation.   In this case a medical fitness chest x-ray for employment purposes performed 5 months prior was identical with sub-diaphragmatic large bowel dilatation despite the patient being asymptomatic and working as a hard laborer.

The large amount of gas under the diaphragm on chest x-ray causes concern in the unaware of a perforation and is one cause of a pseudopneumoperitoneum.
