Abdominal aortic aneurysm differential diagnosis
An abdominal aortic aneurysm should be differentiated from other causes of abdominal pain such as acute cholecystitis, gastrointestinal bleeding, perforated peptic ulcer, ischemic bowel, nephrolithiasis, pyelonephritis, appendicitis, cholelithiasis, large bowel obstruction, small bowel obstruction, pancreatitis, musculoskeletal pain, myocardial infarction, and urinary tract infection.
Differentiating Abdominal Aortic Aneurysm from other Diseases
- A patient becomes symptomatically after abdominal aortic rupture, so the differentiation is according to the rupture which causes acute abdomen signs and symptoms.
- Non-symptomatic AAA is diagnosed through abdominal ultrasound with no other differentials.
- In a patient with a suspected abdominal aortic aneurysm, the following conditions also need to be considered:
- Acute cholecystitis
- Gastritis and peptic ulcer disease
- Gastrointestinal bleeding
- Ischemic bowel
- Large bowel obstruction
- Small bowel obstruction
- Musculoskeletal pain
- Myocardial infarction
- Urinary tract infection in women
