Differential Diagnosis for Epigastric Pain with Elevated WBC

Single Most Likely Diagnosis

  • Peptic Ulcer Disease: This condition is a common cause of epigastric pain and can lead to an elevated white blood cell (WBC) count if there is associated inflammation or infection. The pain is typically described as burning or gnawing and can be related to eating.

Other Likely Diagnoses

  • Gastroesophageal Reflux Disease (GERD): While GERD more commonly presents with heartburn, it can cause epigastric pain. An elevated WBC count might be seen if there's an inflammatory component or if the patient has developed a complication like esophagitis.
  • Acute Pancreatitis: This condition presents with severe epigastric pain radiating to the back and is often associated with an elevated WBC count due to the inflammatory response. Triggers can include gallstones or excessive alcohol use.
  • Cholecystitis: Inflammation of the gallbladder, often due to gallstones, can cause epigastric pain and an elevated WBC count. The pain may radiate to the right shoulder.

Do Not Miss Diagnoses

  • Myocardial Infarction: Although the pain of a heart attack is typically described as chest pain, it can sometimes be felt in the epigastric region, especially if the inferior wall of the heart is involved. An elevated WBC count can occur due to the stress response and potential for myocardial rupture.
  • Aortic Dissection: This is a life-threatening condition where there is a tear in the aorta's inner layer. The pain can be epigastric if the dissection involves the abdominal aorta and can be associated with an elevated WBC count due to the inflammatory response.
  • Perforated Viscus: A hole in the stomach or intestine can lead to peritonitis, which causes severe abdominal pain, including epigastric pain, and a significant elevation in WBC count due to the infection.

Rare Diagnoses

  • Carcinoid Syndrome: Although rare, carcinoid tumors can produce substances that lead to flushing, diarrhea, wheezing, and heart valve abnormalities. Epigastric pain can occur if the tumor is located in the stomach or duodenum, and an elevated WBC count might be seen due to the body's response to the tumor.
  • Zollinger-Ellison Syndrome: This is a rare disorder characterized by excessive gastric acid production due to a gastrin-producing tumor. It can cause severe peptic ulcers and epigastric pain, with an elevated WBC count possible due to the associated inflammation.
