Differential Diagnosis for Upper Abdominal/Epigastric Pain in a 4-Year-Old

Single Most Likely Diagnosis

  • Viral Gastroenteritis: This is the most common cause of abdominal pain in children, often accompanied by vomiting, diarrhea, and fever. The symptoms are usually self-limiting and resolve within a few days.

Other Likely Diagnoses

  • Constipation: Can cause significant abdominal pain in children, often localized to the upper abdomen. It's a common issue in pediatric patients and can be managed with dietary changes and laxatives if necessary.
  • Gastroesophageal Reflux Disease (GERD): Can cause epigastric pain, especially after eating. It's more common in infants but can occur in older children, especially those with a family history of GERD.
  • Functional Abdominal Pain: A common condition in children characterized by recurrent abdominal pain without an identifiable cause. It's often related to stress or anxiety.

Do Not Miss Diagnoses

  • Appendicitis: Although less common in young children, appendicitis can present with upper abdominal pain that migrates to the right lower quadrant. It's crucial to consider this diagnosis due to the risk of perforation and peritonitis if not promptly treated.
  • Intussusception: A condition where a part of the intestine telescopes into another, causing bowel obstruction. It's a medical emergency that requires immediate attention, presenting with severe abdominal pain, vomiting, and sometimes bloody stools.
  • Pyloric Stenosis: Typically presents in infants but can occasionally be seen in older children, causing projectile vomiting and epigastric pain due to gastric outlet obstruction.

Rare Diagnoses

  • Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease and ulcerative colitis can cause chronic abdominal pain, diarrhea, and weight loss. Although rare in young children, they should be considered in the differential diagnosis of chronic abdominal pain.
  • Pancreatitis: Can cause severe upper abdominal pain radiating to the back, more commonly seen in older children and adolescents, especially those with a family history of pancreatitis or certain metabolic disorders.
  • Hepatic or Biliary Disease: Conditions affecting the liver or biliary system, such as hepatitis or choledochal cysts, can cause upper abdominal pain but are less common in children.
