Fetal and neonatal liver tumours

Area of Science:

• Pediatric Oncology
• Fetal Medicine
• Diagnostic Imaging

Background:

• Liver tumors in fetuses and newborns are uncommon, representing approximately 5% of all neonatal tumors.
• Common types include benign vascular tumors and mesenchymal hamartomas, with hepatoblastoma being a significant malignant possibility.
• Prenatal diagnosis via ultrasound and MRI is possible but often complicated by tumor complexity.

Purpose of the Study:

• To review the diagnosis, associated conditions, and treatment modalities for pediatric liver tumors.
• To highlight the diagnostic challenges and potential complications in utero and postnatally.
• To outline the spectrum of management strategies for fetal and neonatal liver masses.

Main Methods:

• Review of antenatal and postnatal diagnostic imaging techniques (ultrasound, MRI).
• Analysis of clinical presentations and associated fetal/maternal conditions (polyhydramnios, fetal hydrops, maternal mirror syndrome).
• Summary of treatment options including observation, surgical resection, embolization, and chemotherapy.

Main Results:

• Accurate diagnosis of fetal and neonatal liver tumors can be difficult due to their complex nature.
• In utero complications may include polyhydramnios, fetal hydrops, and maternal mirror syndrome.
• Postnatal symptoms vary, including abdominal distension, cardiac failure, coagulopathy, and bleeding, depending on tumor type.

Conclusions:

• Pediatric liver tumors require a multidisciplinary approach for accurate diagnosis and management.
• Early detection and understanding of potential complications are crucial for optimal outcomes.
• Treatment strategies are tailored to the specific tumor type and clinical presentation, ranging from conservative management to aggressive therapies.
