Thumbprinting
Patient with severe abdominal pain. What does the image show?
Rigler’s/ double wall sign
Free gas (pneumoperitoneum) can be seen on both sides of the bowel wall. This is Rigler’s sign or the double wall sign.
Whenever sharp points or triangles of low density are seen adjacent to loops of bowel, pneumoperitoneum should be suspected.
Note: In patients with an acute abdomen an erect chest X-ray is more sensitive for small volumes of free gas.

What may a liver edge silhouette indicate on an AXR? [1]
When perforation of a duodenal ulcer occurs, and
results in a pneumoperitoneum:
Gas collects in Morison’s pouch (the hepato-renal space), and rise on the supine film to the anterior abdominal wall outlining the edge of the liver
diagnostic of duodenal
perforation.
What pathology is indicated in this AXR? [1]
False Rigler’s/double wall sign
* Be careful not to mistake the gas within two adjacent bowel segments for Rigler’s sign.
* Gas seen on both sides of the bowel wall is contained within adjacent bowel
* There are no black triangles or sharp angles on the outside of the bowel wall
Describe what is seen in this AXR [3]
Small bowel obstruction - features
Centrally located multiple dilated loops of gas filled bowel (arrowheads)
Valvulae conniventes (arrow) are visible - confirming this is small bowel
Describe what is depicted in this AXR [1]
Large bowel obstruction
- Here the colon is dilated down to the level of the distal descending colon. There is the impression of soft tissue density at the level of obstruction (X). No gas is seen within the sigmoid colon.
- Obstruction is not absolute in this patient as a small volume of gas has reached the rectum (arrow).
- An obstructing colon carcinoma was confirmed on CT and at surgery.

A 73-year-old male presents with a 2-hour history of sudden-onset abdominal pain, accompanied by a bowel motion and vomiting. He has a history of non-specific heart problems and takes antihypertensive medication. He also had a previous appendicectomy performed 45 years ago.
Examination of the abdomen reveals a distended and generally tender abdomen with no guarding. There is a scar present in the right iliac fossa and bowel sounds are absent. Rectal examination is unremarkable. An ECG performed is shown below:
