Congenital Bilateral Wilms Tumor: A Case Report

Abstract

Compare to congenital mesoblastic nephroma in fetus, congenital wilms tumor is extremely rare. Herein we report a case of congenital bilateral solid masses on antenatal ultrasound. The mass was evaluated by ultrasonography and contrast computed tomography scan in postnatal period, and the patient was undergoing tumor enucleation separately in short period after neoadjuvant chemotherapy. The diagnosis was confirmed by histology analysis for each side, and the treatment was taken according to the International Society of Pediatric Oncology.
