Fetal Neuroblastoma: Prenatal Ultrasonography and Magnetic Resonance Imaging Findings

Abstract

Neuroblastomas are the second most common type of neonatal tumor originating from embryonic nerve cells. It constitutes 20% of all fetal tumors and is incidentally detected on routine ultrasonography (US). Magnetic resonance imaging (MRI) plays a complementary role to US when diagnosis is difficult. In the absence of poor prognostic factors, treatment is not recommended during the prenatal and neonatal periods, and follow-up imaging is considered sufficient. In this case report, we present the US and MRI findings of a fetal neuroblastoma detected in the 25th week of pregnancy in the left fetal adrenal gland.
