Differential Diagnosis

The patient presents with multiple gallstones, raised alkaline phosphatase (ALP), fever, and a total count of 21,000. Here's a structured approach to the differential diagnosis:

  • Single Most Likely Diagnosis

    • Cholecystitis: This condition is characterized by inflammation of the gallbladder, often due to gallstones causing obstruction. The presence of fever, elevated white blood cell count (21,000), and raised ALP supports this diagnosis, as ALP can be elevated in cases of cholestasis or bone disorders, but in this context, it points towards a hepatobiliary issue.

  • Other Likely Diagnoses

    • Cholangitis: Infection of the bile duct, which can occur if a gallstone migrates into and obstructs the common bile duct. Symptoms include fever, jaundice, and elevated liver enzymes, including ALP.
    • Gallstone Pancreatitis: If a gallstone obstructs the ampulla of Vater, it can cause pancreatitis. While the primary symptoms would involve abdominal pain and elevated pancreatic enzymes, the presence of gallstones and systemic inflammation (fever, elevated white blood cell count) could suggest this diagnosis.

  • Do Not Miss Diagnoses

    • Sepsis due to Biliary Obstruction: If the biliary obstruction leads to infection that progresses to sepsis, it's crucial to identify and treat promptly due to its high mortality rate. The presence of fever and a high white blood cell count could indicate a severe infection.
    • Mirizzi Syndrome: A rare condition where a gallstone becomes impacted in the cystic duct and causes obstruction of the common bile duct, leading to jaundice and potentially cholangitis. It's less likely but critical to consider due to its potential for severe complications.

  • Rare Diagnoses

    • Primary Sclerosing Cholangitis (PSC): A chronic liver disease characterized by inflammation and scarring of the bile ducts inside and outside the liver. While it could explain elevated ALP, it's less directly related to the acute presentation of fever and high white blood cell count.
    • Primary Biliary Cholangitis (PBC): An autoimmune disease of the liver characterized by a progressive destruction of the bile ducts within the liver. It's less likely given the acute presentation but could be considered in the differential for chronic elevations in ALP.
