Cross Testicular Ectopia: A Rare Migration Anomaly of theTesticle

Öz

Cross testicular ectopia is an extremely rare congenital testicular migration anomaly in which both testes migrate to the same hemiscrotum, usually associated with inguinal hernia. Although the exact incidence is unknown, fewer than 150 cases have been reported in published studies, in contrast to undescended testis which is seen in approximately 1% of cases. In this case report, we aimed to present a cross testicular ectopia, a rare testicular migration anomaly diagnosed by preoperative ultrasonography. A 25-month-old male infant with swelling in the right inguinal region since birth was referred to our radiology unit for imaging because of the presence of an inguinal hernia on the right and failure to palpate both testes in the scrotum on physical examination. Ultrasonography performed with a linear probe with a frequency of 14 MHz showed that the scrotum was empty, both testes were observed in the middle part of the right inguinal canal and the presence of intestinal ans herniated into the canal. Early diagnosis and treatment is extremely important in these patients due to the fertility problems and risk of malignancy that may develop in the future.

Çapraz Testis Ektopisi: Testisin Nadir Migrasyon Anomalisi

Öz

Çapraz testis ektopisi, her iki testisin aynı hemiskrotuma göç ettiği genellikle kasık fıtığı ile ilişkili son derece nadir görülen konjenital testis migrasyon anomalisidir. Kesin insidansı bilinmemekle beraber yaklaşık %1 oranında görülen inmemiş testisin aksine yayınlanmış çalışmalarda 150'den az vaka bildirilmiştir. Bu vaka taktiminde ameliyat öncesi ultrasonografi ile tanısı konulan oldukça nadir bir testis migrasyon anomalisi olan çapraz testis ektopisinin sunulması amaçlanmıştır. Doğumundan bu yana sağ kasık bölgesinde şişlik bulunan 25 aylık erkek bebek, fizik muayenesinde sağda inguinal herni varlığı ve skrotumda her iki testisin palpe edilememesi üzerine görüntüleme amacı ile radyoloji birimimize yönlendirildi. Hastanın 14 MHz frekansa sahip lineer prob ile yapılan ultrasonografisinde skrotumun boş olduğu, her iki testisin sağ ingünal kanal orta kesimde yerleşik olduğu ve kanala herniye bağırsak anslarının varlığı görüldü. Bu hastalarda ilerde gelişebilecek fertilite sorunları ve malignite riski nedeniyle erken tanı ve tedavi son derece önem arz etmektedir.
