The gallbladder shows normal distention. There is irregular thickening of the GB wall involving the posterior wall in the fundal region of the GB. This thickening shows a mass-like appearance and measures approximately 31 mm x 25 mm. The omentum adheres to the gallbladder in this region and there is loss of interface between the adjacent fat planes and the thickened wall of the GB. Minimal sludge is noted in the GB lumen; however, there is no evidence of any detectable calculus within the gallbladder lumen. The rest of the GB wall appears to be relatively normal. A very thin rim of pericholecystic fluid is evident. The hepatic flexure of the colon also appears to be adhered to the omentum and to the fundus of the gall bladder. There also appears to be adhesions between the gallbladder fundus and the inferior border of the liver, however, the interface between the liver and the gallbladder is maintained. Mildly increased vascularity is noted in this region.
The CBD is normal in caliber. There is no intrahepatic biliary dilatation. No obvious calculus/shadowing echogenic lesion detected in the pericholecystic region to suggest expelled gallbladder calculus. No obvious free fluid noted in the Morison's pouch or perisplenic area.
