Differential Diagnosis for Abdominal Pain in a 5-Year-Old

Single Most Likely Diagnosis

  • Viral Gastroenteritis: This is the most common cause of abdominal pain in children, often accompanied by symptoms like vomiting, diarrhea, and fever. The high prevalence of viral infections in this age group and the typical presentation make it the single most likely diagnosis.

Other Likely Diagnoses

  • Constipation: A common issue in children, constipation can cause significant abdominal pain and is often overlooked. Dietary habits, fluid intake, and bowel movement patterns can contribute to this condition.
  • Urinary Tract Infection (UTI): UTIs can present with abdominal pain, especially if the infection involves the kidneys. Symptoms like dysuria, frequency, and fever may also be present.
  • Appendicitis: Although less common in younger children, appendicitis is a significant concern due to the risk of perforation. Symptoms can include pain that migrates to the right lower quadrant, fever, and vomiting.

Do Not Miss Diagnoses

  • Intussusception: A condition where a part of the intestine telescopes into another, intussusception is a medical emergency that can cause severe abdominal pain, vomiting, and bloody stools. It's crucial to diagnose promptly to avoid complications.
  • Midgut Volvulus: A twisting of the intestine that can cut off blood flow, midgut volvulus is a surgical emergency. Symptoms include severe abdominal pain, vomiting, and possible bloody stools.
  • Pneumonia: Lower lobe pneumonia can cause referred abdominal pain, especially if the diaphragm is irritated. Fever, cough, and difficulty breathing may also be present.

Rare Diagnoses

  • Henoch-Schönlein Purpura (HSP): A form of vasculitis that can cause abdominal pain, HSP is also associated with a characteristic rash, joint pain, and sometimes kidney involvement.
