Insights
Umbilical venous catheter (UVC) misplacement can cause liver collections mimicking tumors on ultrasound. Familiarity with imaging findings helps avoid unnecessary biopsies and complications in pediatric patients.
Area of Science:
- Radiology
- Pediatric Imaging
- Perinatal Care
Background:
- Umbilical venous catheters (UVCs) are commonly used in perinatal care.
- Misplacement of UVCs can lead to extravasation into the liver parenchyma.
- This can result in findings suspicious for tumoral lesions on ultrasound.
Purpose of the Study:
- To familiarize clinicians and radiologists with the radiological findings of liver collections caused by UVC malposition.
- To prevent unnecessary liver biopsies and complications in pediatric patients.
Main Methods:
- Review of sonographic and computed tomographic (CT) images.
- Focus on liver collections resulting from UVC malposition.
Main Results:
- UVC extravasation can create unusual liver findings on imaging.
- These findings may mimic tumoral lesions, leading to diagnostic challenges.
Conclusions:
- Radiologists and clinicians must recognize imaging features of UVC malposition to avoid misdiagnosis.
- Understanding these findings is crucial for appropriate management and preventing complications.
Abstract:
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.
