Multi-detector contrast-enhanced computed tomography. Coronal reformatted images obtained before (A) and after (B) oral administration of 500cm3of 3 percent diluted diatrizoate meglumine are shown. In (A) extraluminal air can be seen in the perihepatic space (asterisk) as well as in the hepatoduodenal ligament (arrow). The fluid component of the abscess (circle) can also be detected beside the gallbladder. In (B) the extraluminal leakage of the water-soluble iodinated contrast media can be well appreciated at the level of the hepatoduodenal ligament (arrowhead) in place of the extraluminal air.
