Figure 2.

Six-year-old boy with a congenital portohepatic shunt complicated by a biopsy-proven FNH measuring 7 cm diameter (white star). (a) Contrast-enhanced CT scan at diagnosis shows an abnormal and large communication between the right portal branch (RPB) and the right hepatic vein (RHV). (b) Phlebography with opacification of the shunt between the RPB and the RHV. Closure of the shunt was performed by interventional radiology. (c) MRI performed seven years later shows the disappearance of FNH on the T2-weighted images. No enhancement was present at the arterial phase after gadolinium injection (not shown). (d) Note the normal aspect of the portal bifurcation (RPB and left portal branch (LPB)) on coronal MIP reconstruction of the T2-balanced sequence.
