Understanding Crossed Testicular Ectopia: An Embryological Perspective Through Case Presentation
Abstract: Background: Crossed testicular ectopia (CTE), or transverse testicular ectopia, is a rare congenital anomaly in which both testes descend into the same hemiscrotum. It is frequently associated with inguinal hernia, persistent M?llerian duct syndrome (PMDS), hypospadias, and other genitourinary abnormalities. Fewer than 150 cases have been reported worldwide, making it an important subject for embryological and clinical study. Aim: To present two cases of CTE and discuss the embryological perspectives and clinical implications, highlighting the importance of early recognition and surgical management. Methods: Two infants presenting with an ipsilateral inguinal hernia and a contralateral non?palpable testis were evaluated. Surgical exploration confirmed that both testes were located in the same inguinal canal, with preservation of normal spermatic cord origin. Herniotomy and orchiopexy were performed. A literature review was conducted to analyse embryological theories and classification. Results: Both cases demonstrated classical features of CTE. No M?llerian remnants were identified. Surgical outcomes were favourable, with successful orchiopexy and hernia repair. Review of literature revealed multiple embryological hypotheses, including Wolffian duct adhesion, aberrant gubernacular development, defective inguinal ring formation, and the mechanical influence of M?llerian remnants. CTE is classified into three types: Type I (hernia alone), Type II (associated with M?llerian remnants), and Type III (associated with other genitourinary anomalies). Conclusion: CTE exemplifies the complex interplay between embryological development and clinical manifestation. Early recognition and timely surgical intervention are essential to prevent complications such as infertility, malignancy, and recurrent hernia. Case?based reporting enriches understanding of its pathogenesis and guides operative strategies.
