Differential Diagnosis for Bowel Obstruction Mimicking AAA

Single Most Likely Diagnosis

  • Bowel Obstruction: This is the most likely diagnosis because the symptoms of bowel obstruction, such as abdominal pain, nausea, vomiting, and abdominal distension, can be similar to those of an abdominal aortic aneurysm (AAA). The pain associated with bowel obstruction can sometimes be severe and may radiate to the back, mimicking the pain pattern of AAA.

Other Likely Diagnoses

  • Mesenteric Ischemia: This condition, which involves insufficient blood flow to the intestines, can cause severe abdominal pain and may mimic the symptoms of AAA or bowel obstruction.
  • Diverticulitis: Inflammation of the diverticula in the colon can cause severe abdominal pain, changes in bowel habits, and other symptoms that might be confused with those of bowel obstruction or AAA.
  • Kidney Stones: Severe pain from kidney stones can sometimes be mistaken for the pain associated with bowel obstruction or AAA, especially if the stones are causing an obstruction in the ureter.

Do Not Miss Diagnoses

  • Abdominal Aortic Aneurysm (AAA): Although the question asks about bowel obstruction mimicking AAA, it's crucial not to miss a real AAA, as it is a life-threatening condition requiring immediate medical attention.
  • Ectopic Pregnancy: In women of childbearing age, an ectopic pregnancy can cause severe abdominal pain and internal bleeding, mimicking other conditions. It's a medical emergency that must be promptly diagnosed and treated.
  • Ruptured Ovarian Cyst: This condition can cause sudden, severe abdominal pain and is a medical emergency, especially if there is significant internal bleeding.

Rare Diagnoses

  • Intussusception: A condition where a part of the intestine slides into an adjacent part, potentially causing bowel obstruction. It's more common in children but can occur in adults, often with a lead point such as a tumor.
  • Volvolus: A twisting of a portion of the intestine, which can cut off blood flow and lead to tissue death. It's a rare cause of bowel obstruction but requires urgent treatment.
  • Inferior Mesenteric Artery Aneurysm: Aneurysms of the inferior mesenteric artery are rare and can cause abdominal pain and other symptoms similar to those of bowel obstruction or AAA.
