Differential Diagnosis for 27-year-old Female with Epigastric Pain and Elevated Liver Enzymes

Single Most Likely Diagnosis

  • Cholelithiasis with Choledocholithiasis: This condition is highly likely given the patient's history of obesity and type 2 diabetes, which are risk factors for gallstones. The presentation of epigastric pain radiating to the back, elevated liver enzymes, elevated total bilirubin, and a dilated common bile duct (CBD) on imaging strongly suggests a gallstone obstructing the CBD.

Other Likely Diagnoses

  • Chronic Pancreatitis: The patient's epigastric pain radiating to the back could be indicative of pancreatitis, especially with a history of obesity and type 2 diabetes. Elevated liver enzymes could also be seen in this condition due to the close proximity of the pancreas to the liver and potential for bile duct obstruction.
  • Acute Cholangitis: Although the patient has normal vitals, which might not initially suggest an infectious process, acute cholangitis should be considered, especially if there's a suspicion of bile duct obstruction. The elevated bilirubin and dilated CBD support this possibility.

Do Not Miss Diagnoses

  • Pancreatic Cancer: Although less likely in a young patient, pancreatic cancer can present with similar symptoms, including pain, jaundice (elevated bilirubin), and a dilated CBD. Given the potential for a fatal outcome if missed, it's crucial to consider this diagnosis.
  • Bile Duct Stricture or Tumor: Any obstruction of the bile duct, whether due to a stricture or a tumor, could present similarly and has significant implications for treatment and prognosis.

Rare Diagnoses

  • Primary Sclerosing Cholangitis (PSC): This is a rare chronic liver disease characterized by inflammation and scarring of the bile ducts inside and outside the liver. While it could explain the elevated liver enzymes and dilated CBD, it's less common and typically associated with inflammatory bowel disease.
  • Primary Biliary Cholangitis (PBC): Another rare autoimmune disease of the liver, characterized by a progressive destruction of the bile ducts within the liver. It could present with elevated liver enzymes but is less likely to cause a dilated CBD or the specific pattern of pain described.
