Antenatally Detected Mature Teratoma in an Undescended Testis

Introduction

Foetal abdominal mass is an uncommon condition requiring careful evaluation. Antenatal ultrasonography (US) provides an opportunity for the early detection of foetal intra-abdominal masses, allowing surgeons to prepare for early postnatal intervention. Undescended testis is a common condition with a prevalence of 3.4% at birth in full-term newborns. It is considered to be a major risk factor for the development of testicular germ cell tumour in later life. This report describes a rare case of mature teratoma in an undescended testis detected as a foetal abdominal mass.
