Imaging of Prenatal and Neonatal Intra-abdominal Genitourinary Tumors: a Review of the Literature

Megan Guerre et al. Curr Urol Rep. 2022 Mar.

Abstract

Purpose of review: Our goal was to summarize current literature related to imaging of intra-abdominal genitourinary tumors diagnosed in the prenatal or neonatal period. Our specific interests included modalities used, diagnoses made, changing incidence of tumor detection, and proposed future uses of these imaging modalities.

Recent findings: Fetal and neonatal MRI have been used as an adjunct to ultrasound for better characterization and assessment of congenital mesoblastic nephroma, juvenile granulosa cell tumor, and other tumors. Despite recent literature describing fetal and neonatal MRI, it is not yet possible to determine whether its use is changing the incidence of tumor detection. Improvements in imaging technology, specifically the use of fetal MRI, have allowed for earlier identification of genitourinary masses with improved capability for diagnosis, surveillance, surgical planning, and sometimes prenatal treatment of the malignancy and related diagnoses, with a goal of preventing pregnancy and delivery complications.

Keywords: Fetal MRI; Genitourinary; Genitourinary tumors; Imaging; Neoplasm; Ultrasound.
