Hepatisation of the gallbladder
Hepatisation of the gallbladder is a sonographic entity in which the gallbladder lumen is entirely filled with tumefactive sludge giving the gallbladder a similar appearance to liver parenchyma. It is one of the causes of non-visualisation of the gallbladder on sonography.
In the setting of cholelithiasis, calculi present in the neck of gallbladder leads to excessive accumulation of sludge leading to increased echogenicity of the gallbladder, resembling the echogenicity of the liver.
Hepatisation of the gallbladder can be easily differentiated from normal liver parenchyma as it demonstrates absent colour flow on Doppler imaging.
