Type I is characterised by complete lack of intrahepatic portal venous blood flow due to an end to side fistula between main portal vein and the inferior vena cava. Type II on the other hand is characterised by partial preservation of portal blood supply to liver and side to side fistula between main portal vein or its branches and mesenteric, splenic, gastric, and systemic veins. The presentation of these patients is variable. Focal liver lesions, most commonly nodular regenerative hyperplasia, are an important clue to the underlying condition. This pictorial essay covers imaging characteristics in abdominopelvic region.<\/jats:p>","DOI":"10.1155\/2015\/181958","type":"journal-article","created":{"date-parts":[[2015,12,13]],"date-time":"2015-12-13T21:01:29Z","timestamp":1450040489000},"page":"1-7","source":"Crossref","is-referenced-by-count":4,"title":["Congenital
