Umbilical venous catheters (UVCs) have become a part of routine perinatal care. In the case of its misplacement, extravasation into liver parenchyma might be observed and unusual findings might be detected and a suspicion of tumoral lesions emerges during the ultrasound examination. To avoid the unnecessary liver biopsies and catastrophic complications of UVC misplacement in the pediatric population, clinicians and radiologists must be familiar with the radiological findings. We aimed to present sonographic and computed tomographic images of liver collections resulting from UVC malposition.
