An asymptomatic patient with a history of Hepatitis B has an annual abdominal ultrasound. The gallbladder is demonstrating:

• A. Pneumobilia
• B. Cholesterolosis
• C. Floating gallstones
• D. Adenomyomatosis

Answer: (D)

The presence of adenomyomatosis in the gallbladder is characterized by a thickened gallbladder wall with a hyperplastic change involving the mucosa and muscularis layer, which can be visualized on ultrasound. This condition is often asymptomatic and commonly discovered incidentally during imaging studies like abdominal ultrasounds. Patients with a history of liver conditions such as Hepatitis B may have increased surveillance through imaging, potentially uncovering incidental findings like adenomyomatosis. This condition does not typically lead to symptoms or complications, making it a suitable finding for an asymptomatic patient. The ultrasound would show characteristic features, including the "ring down" artifact or "comet tail" sign caused by small cystic spaces within the thickened wall. The other conditions, while relevant in the context of gallbladder pathology, generally have different characteristics or clinical implications. For example, pneumobilia would indicate air presence in the biliary system and often suggests a pathological process such as a fistula. Cholesterolosis involves the accumulation of cholesterol within the gallbladder wall, leading to a "strawberry gallbladder" appearance, and is typically associated with a background of gallstone disease or hyperlipidemia.
