Ultrasound Video showing Gallbladder Mucocele.

This video shows Gallbladder Mucocele. A gallbladder mucocele is the distention of the gallbladder by an inappropriate accumulation of mucus. Decreased bile flow, decreased gallbladder motility, and altered absorption of water from the gallbladder lumen are predisposing factors to biliary sludge. The term gallbladder mucocele refers to an over distended gallbladder filled with mucoid or clear and watery content. Usually non-inflammatory, it results from outlet obstruction of the gallbladder and is commonly caused by an impacted stone in the neck of the gallbladder or in the cystic duct. A mucocele is formed by excessive secretion of mucus by the gallbladder wall. Histologically it has been described as cystic mucosal hyperplasia. The thick mucus congeals with the bile and causes distension of the gallbladder and sometimes the common bile duct and extrahepatic ducts. Eventually, pressure necrosis of the gallbladder wall can occur, resulting in bile peritonitis. Clinical studies have shown that patients with hyperadrenocorticism or hypothyroidism may be at increased risk. What are the most common clinical signs? Vomiting, lethargy, cranial abdominal pain, and sometimes icterus (the technical term for jaundice ) are seen in patients with a gallbladder mucocele. Laboratory abnormalities often include dehydration, elevated WBC count, and elevation in liver enzymes and Bilirubin. The gallbladder is enlarged, with stationary echogenic contents often in a stellate (arranged in a radiating pattern like that of a star ) pattern. Often the cranial abdominal mesentery/fat surrounding the gallbladder is hyperechoic and free fluid may be present. The extrahepatic ducts and proximal aspect of the common bile duct can be distended as well.
