A fern frond‐like peripheral portal vein thrombosis in a neonate: A case report

Abstract

Although the ultrasonographic (US) features of portal vein thrombosis in premature newborns have been described, there are very few reports on thrombosis of the peripheral branches of the portal vein. Here, I describe a case of peripheral portal vein branch thrombosis in a neonate, appearing on US imaging with a fern frond pattern.
