Cholesterol polyps form on which gallbladder structure, linked to a specific biliary pathology?

• A. Rokitansky-Aschoff Sinuses
• B. Adenomyomatosis
• C. Cholesterolosis
• D. Biloma

Answer: (C)

Cholesterol polyps arise from the gallbladder mucosa—the lining of the gallbladder. In cholesterolosis, lipid-laden macrophages accumulate in the lamina propria of the mucosa, causing mucosal projections that extend into the lumen as multiple cholesterol polyps. They are not true neoplasms and are linked to a biliary condition where cholesterol deposits occur in the gallbladder wall. The other choices describe different gallbladder structures or pathologies: Rokitansky-Aschoff sinuses are mucosal invaginations seen with adenomyomatosis, adenomyomatosis involves wall thickening with intramural diverticula, and a biloma is a bile collection outside the biliary tract.
