Floating (Ectopic) gallbladder is characterized by which description?

• A. Fusiform dilation of the CBD
• B. Two gallbladders
• C. Surrounded by peritoneum, connected to liver by mesentery
• D. Small recessed area in neck

Answer: (C)

A floating (ectopic) gallbladder is one that remains suspended within the peritoneal cavity by a mesentery and is not firmly attached to the liver. Because of this long mesenteric stalk, the gallbladder is mobile and can sit in unusual locations, yet it remains surrounded by peritoneum. That combination—peritoneal enclosure plus a mesenteric connection to the liver—is the defining feature of a floating gallbladder. Fusiform dilation of the common bile duct describes a bile duct abnormality, not the gallbladder’s position. Two gallbladders indicate duplication, which is a different variation. A small recessed area in the neck does not capture the mobility and peritoneal relationship characteristic of a floating gallbladder.
