Crossed Testicular Ectopia (CTE), A rare anomaly: Case Report and Review of the Literature

Abstract

BACKGROUND: A relatively uncommon urogenital anomaly known as crossed testicular ectopia (CTE) can be defined by the emigration of one testis into the opposing inguinal canal, which could possibly be ectopic in the abdominal cavity, inguinal region, or even descend to the opposing hemi-scrotum. Following a review of the literature, the most common classification is to subdivide CTE into three categories based on associations: I, which tends to be associated with inguinal hernia alone; II, which is predominantly associated with persistent mullerian remnants; and III, which is most frequently associated with other anomalies without mullerian remnants. CASE PRESENTATION: We describe a rare CTE case in a two-year-old kid who presented with a nonpalpable right testis, an empty right hemi-scrotum, and a MRI that showed both testicles were located in the left inguinal canal. Laparoscopy was used to make the final diagnosis, which was followed by a left inguinotomy with trans-septal tension-free orchiopexy. CONCLUSION: The cornerstone of surgical care consists of proper testicular fixation into the scrotum, a search for other anomalies such as Mullerian duct remnants, and long-term follow-up due to the potential risk of malignancy.
