Overview

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

In a patient with a suspected abdominal aortic aneurysm, the following conditions also need to be considered:

Classification of acute abdomen based

on etiology

Presentation Clinical findings Diagnosis Comments
Fever Rigors and Chills Abdominal Pain Jaundice Hypotension Guarding Rebound Tenderness Bowel sounds Lab Findings Imaging
Common causes of
