Some of these cystic spaces demonstrate low signal foci on the T2 weighted imaging in keeping with calculi. There are low signal foci within the fundus of the gallbladder also in keeping with a dependent gallbladder calculus. There is a calculus within the neck of the gallbladder measuring approximately 8 mm. No fluid surrounding the gallbladder. No intra or extrahepatic biliary tree dilatation.
