Sludge balls are also known as which term?

• A. Sludge
• B. Gallbladder sludge
• C. Tumefactive sludge
• D. Biliary sludge

Answer: (C)

Sludge balls are formed when biliary sludge coalesces into mobile, round clumps inside the gallbladder. This ball-like, swollen appearance is described as tumefactive sludge. On ultrasound, these appear as echogenic, non-shadowing masses that can move with changes in position, helping distinguish them from true stones, which typically cast posterior acoustic shadow and are often more calcified. General biliary sludge refers to diffuse, non-specific layering material in the gallbladder, not the ball-like aggregates. Gallbladder sludge or biliary sludge are broader terms for the material itself, not the specific ball form. Therefore, the most precise term for sludge that forms balls is tumefactive sludge.
