92-year-old woman with a hepatic caudal lobe abscess penetrating into the IVC

FINDINGS: Coronal CECT demonstrates floating balloon shaped hypo-attenuation, which favors intravascular abscess over a septic thrombus (A arrow). An abscessogram shows an abcess floating in the IVC (B dashed arrow).

TECHNIQUE: Coronal CECT. Images were acquired with TOSHIBA Aquilion 16-slices CT scanner at 172 mAs, 120 kV, and 5 mm slice thickness after intravenous administration of 100 mL Iopamidol (Iopamidol) 300 mg iodine/mL (A). An abcessogram after administration of 10ml of Amidotrizoic Acid (Urografin injection 60%) 292 mg iodine/mL through drainage tube (B).
