(a and b) Thin maximum intensity projection of computed tomography image (a) in coronal plane before embolization showing dilated left hepatic artery (thin arrow) opening in to a dilated left branch of portal vein (thick arrow) suggestive of congenital hepatic arterioportal fistula. (b) Thin maximum intensity projection of computed tomography image in coronal plane after embolization showing the vascular plug (outlined arrow) in the region of fistula. Also, the caliber of portal vein has significantly reduced

Subsequently, a contrast-enhanced computed tomography (CECT) scan of the abdomen [Figure 1a] confirmed the above findings with the presence of an arterioportal fistula between the left hepatic artery and left branch of portal vein. Follow-up CECT scan [Figure 1b performed at 6 months was unremarkable without out any recurrence/persistence of the fistula with normal enhancement of the liver.
