Adenomyomatosis of the gallbladder as seen on ultrasound [2] Non-contrast abdominal ultrasound and contrast-enhanced ultrasound (CEUS) of adenomyomatosis of the gallbladder: [3] a The fundus of the gallbladder wall was thickened and the GB wall was obscure. b The intramural echogenic foci were detected by high frequency transducer.
Adenomyomatosis describes a diseased state of the gallbladder in which the gallbladder wall is excessively thick, due to proliferation of subsurface cellular layer. It is characterized by deep folds into the muscularis propria. Ultrasonography may reveal the thickened gallbladder wall with intramural diverticulae, called Rokitansky-Aschoff sinuses.

[4] [5] [6] Ultrasound can also distinguish between diffuse, segmental, and localized variants of adenomyomatosis based on morphology. [5] [6] In some cases, gallbladder wall thickening may be seen on ultrasound but is poorly defined and lacking specificity, particularly if the characteristic Rokitansky-Aschoff sinuses are not visualized.
Gallbladder diseases are diseases involving the gallbladder and is closely linked to biliary disease, with the most common cause being gallstones (cholelithiasis). [1] [2]The gallbladder is designed to aid in the digestion of fats by concentrating and storing the bile made in the liver and transferring it through the biliary tract to the digestive system through bile ducts that connect the ...
Liver cell adenomatosis is also associated with becoming hepatocellular carcinoma. [11] Like hepatic adenomas, they are diagnosed with imaging and biopsies as needed. Treatment of liver cell adenomatosis is difficult due to the multiple, widespread lesions. Liver imaging should be reviewed to see if it is possible to surgically remove the ...
The human gallbladder is a hollow grey-blue organ that sits in a shallow depression below the right lobe of the liver. [2] In adults, the gallbladder measures approximately 7 to 10 centimetres (2.8 to 3.9 inches) in length and 4 centimetres (1.6 in) in diameter when fully distended. [3]
Normally, the downstream gallbladder stores and concentrates the bile which originates in liver hepatocyte cells and is released into the microscopic component of the biliary system by the liver. Through aggregating tubules of increasing diameter, the bile leaves the liver and reaches the upstream (proximal) component of the common bile duct.
