74-year-old male with acalculous hemorrhagic cholecystitis.

FINDINGS: Unenhanced CT of the abdomen on (A) day 2 and (B) day 9 of hospitalization showed increasing hyperdense (44HU) intraluminal content in the distended gallbladder, interpreted as biliary sludge (*). C) Ultrasound on hospital day 16 showed a distended gallbladder with thickened walls (white arrow) and echogenic layered material presumed to be sludge (*).

TECHNIQUE: A) and B) Axial CT of the abdomen without oral or intravenous contrast. mAs per slice: 200 mAs, kilovoltage: 120 kV, slice thickness: 5 mm

C) Real time ultrasound of the gallbladder using curved array transducer at 4 MHz.
