title: Sonographic diagnosis of hepatic erosion caused by umbilical catheterization.
abstract: The use of umbilical venous catheter (UVC) is common practice in neonatal units. The traumatic injury of the hepatic parenchyma is a rare complication. We present a case of a preterm newborn underwent ultrasound examination revealing a hyperechogenic focal lesion at the confluence of the hepatic veins This finding, according to patient's history, was suspected to be a traumatic injury of the liver parenchyma caused by umbilical catheterization. During sonographic follow-up this lesion gradually reduced until complete resolution. Finally, when focal hyperechogenic hepatic lesion is incidentally detected in newborn with history of UVC placement, the radiologists must consider the traumatic etiology.
