 Fig. 1
Initial CT scan. (A, B) CT scan shows 2.8×2.6 cm ill-defined low attenuating lesion with peripheral enhancement at the liver segment 8 with dilation of the right intrahepatic duct. CT, computed tomography.

Endoscopic retrograde cholangiopancreatography. (A) Cholangiogram shows focal stricture at the origin of the right intrahepatic duct. (B) A 7 F 15 cm straight plastic stent was inserted into the right intrahepatic duct.

Fig. 3
(A) CT scan shows proximal migration of a previously inserted plastic stent that passes through the liver capsule. (B) CT scan shows 5.3×2.9 cm central low attenuating lesion with rim-like enhancement at the liver segment 8. (C) CT scan shows 5.3×2.7 cm central low attenuating lesion with rim-like enhancement at liver segment 7 and right pleural effusion. CT, computed tomography.

Fig. 4
A 7 F 10 cm double pigtail stent was inserted into the right posterior sectoral duct. Percutaneous catheter drainage tubes inserted for liver abscess and right pleural effusion were also observed in this image.

Fig. 5
Computed tomography scan shows decreased size of central low attenuating lesion with rim-like enhancement at (A) liver segment 8 (4.4×3.5 cm) and (B) segment 7 (2.2×1.8 cm).
