Differential Diagnosis for Contracted Gallbladder in a Pediatric Patient
Single Most Likely Diagnosis
- Chronic Cholecystitis: This condition is characterized by chronic inflammation of the gallbladder, often due to gallstones, which can lead to a contracted gallbladder. In pediatric patients, it might be associated with conditions like sickle cell disease or other hemolytic disorders that increase the risk of gallstones.
Other Likely Diagnoses
- Gallstones: The presence of gallstones is a common cause of gallbladder contraction in both adults and children. In pediatric patients, gallstones can be associated with various conditions, including hemolytic diseases, obesity, and total parenteral nutrition.
- Biliary Dyskinesia: This condition involves abnormal movement of the gallbladder and biliary ducts, which can lead to chronic inflammation and contraction of the gallbladder. It's more common in children and can cause chronic abdominal pain.
Do Not Miss Diagnoses
- Sclerosing Cholangitis: Although rare, this condition involves chronic inflammation and scarring of the bile ducts, which can lead to a contracted gallbladder. It's crucial to diagnose early to prevent complications like cirrhosis and bile duct cancer.
- Gallbladder Cancer: Extremely rare in pediatric patients, but it's essential to consider in cases of unexplained gallbladder contraction, especially if associated with other symptoms like jaundice or significant weight loss.
Rare Diagnoses
- Congenital Anomalies of the Biliary System: Certain congenital anomalies, such as a hypoplastic gallbladder, can present with a contracted appearance on imaging. These conditions are rare and often diagnosed incidentally.
- Parasitic Infections: Infections like ascaris or other parasites can cause biliary obstruction and lead to a contracted gallbladder. These are more common in endemic areas and should be considered based on the patient's travel or exposure history.
