Clinical Characteristics, Ultrasonographic Findings, and Treatment of Pediatric Transverse Testicular Ectopia: A 10-Year Retrospective Review

Transverse testicular ectopia with an inguinal hernia: A rare case report

INTRODUCTION

Transverse testicular ectopia (TTE) is a rare congenital condition characterized by migration of both testes through the same inguinal canal and often presents with an inguinal hernia. TTE is associated with various genitourinary anomalies.

CASE PRESENTATION

A three-year-old boy presented with a non-palpable right testis and a palpable undescended left testis in the left inguinal area. Ultrasound (US) indicated the presence of both testes in the left inguinal canal. In surgery, the two testes were found with separated cord and one hernia sac which was dissected and ligated thus the two cords freed. Next, subdartos pouches were created on both scrotum sides, so that testes placed into the left side first, and then a window created in the scrotal septum which allowed the right testis to be translocated and secured in the right subdartos pouch without tension.

DISCUSSION

TTE is a rare condition and the etiology is not definitively known. TTE usually presents with an inguinal hernia and contralateral cryptorchidism. The diagnosis is made during surgery, but some radiological methods can help in diagnosis. Management is usually surgical and involves interventions such as hernia repair, reduction of the testis and orchiopexy. Continuous monitoring is essential for ensuring postoperative testes health and evaluating the risk of malignancy.

CONCLUSION

TTE should be suspected in cases with unilateral empty scrotum and family history of genital disorders. US is critical for accurately localizing the testes, along with surgical exploration, to proceed with the appropriate surgical intervention.

Testicular ectopia: A case report

This paper mainly describes three cases of children with ectopic testis, of which two patients with transverse testicular ectopia (TTE) and one with perineal ectopic testis (PET). All patients who underwent orchidopexy at the same pediatric surgical unit in the Affiliated Hospital of Jining Medical University (Jining, China) between June 2010 and February 2021 were retrospectively evaluated (age range, 14-34 months). A total of two patients (67%) was admitted with asymptomatic unilateral inguinal masses and the contralateral testis missing; the first patient was diagnosed with TTE intraoperatively, whereas the other patient was diagnosed with TTE through physical examination and ultrasound preoperatively. The third patient (33%) was admitted with the right testis missing and a left perineal mass, which was confirmed using PET by physical and ultrasound examination before the operation. The first two patients underwent transseptal orchidopexy, whereas the third patient underwent simple orchidopexy. Postoperative complications were not observed (follow-up, 10-24 months). The low incidence and poor understanding of ectopic testis compels us to report our findings and further discuss this particular disease of testicular ectopia, including its pathogenesis, diagnostic and treatment options.

Transverse testicular ectopia with persistent Mullerian duct syndrome: Report and review of two cases

Transverse testicular ectopia is a rare anomaly characterized by both testes descending through a single inguinal canal. The objective of this study was to investigate the pathogenesis, diagnosis, and treatment of transverse testicular ectopia (TTE) with persistent Mullerian duct syndrome (PMDS), and to deepen the understanding of the disease in clinical. A retrospective analysis of the clinical manifestation, diagnosis, and treatment of two children suffering from TTE with PMDS was conducted. Previous studies on the characteristics, diagnosis, and treatment of this disease were reviewed. The two patients were treated with laparoscopy-assisted transseptal orchidopexy-inguinal evaluation. After the surgery, the two patients recovered well. The follow-up visits were done 3 months after the operation. An ultrasound examination confirmed that the two patients had testes in the orthotopic position and normal size. TTE with PMDS is an exceedingly rare disease. The patients manifested cryptorchidism on one side; contralateral inguinal hernia was suspected. Detailed physical and ultrasound examinations before the operation are the key to the early diagnosis of TTE. Laparoscopic evaluation is helpful for the diagnosis and finding of other abnormalities. Surgical treatment is the only method to cure the disease; long-term follow-up is needed after TTE operation.

Transverse testicular ectopia with persistent mullerian duct syndrome: Misdiagnosis and surgeon's unexpected discovery: A case report

Reports on the occurrence of persistent mullerian duct syndrome along with transverse testicular ectopia are extremely rare globally. In this condition, the fallopian tubes, uterus, cervix and upper two-thirds of vagina occurs alongside transverse testicular ectopia. In most cases, the condition is discovered as an incidental finding during surgical procedures. In this report, we present a case of a 29-year-old Somali male that had scrotal swelling, pain around the inguinal area and perceived infertility for over seven years whom we incidentally found to have a persistent mullerian duct syndrome with transverse testicular ectopia and managed accordingly.

Persistent Müllerian Duct Syndrome: Understanding the Challenges

Persistent Müllerian duct syndrome (PMDS) is a rare autosomal recessive condition defined by the presence of Müllerian duct-derived structures in an otherwise normally masculinized phenotypical and genotypical (46,XY) male. We describe the case of an infant diagnosed with PMDS, managed and followed up for 7 years. The diagnosis of PMDS was made at laparoscopy at 6 months of age for investigation and management of bilateral impalpable testes. A Müllerian structure resembling a uterus with bilateral fallopian tube-like structures was seen in the pelvis, along with bilateral intra-abdominal testes. Gonadal biopsy confirmed normal testicular tissue. The child underwent successful bilateral two-stage Fowler-Stephens orchidopexies. The Müllerian remnant was preserved to maintain testicular vascularity. At the most recent follow-up, the testes are intrascrotal and normal on palpation. There have been no clinical symptoms or concerns with the Müllerian remnant during surveillance with ultrasound and MRI. To date, there are less than 300 cases described in the medical literature, with limited consensus on management. We reflect on challenges the condition poses, including fertility preservation in PMDS, testicular and Müllerian malignancy risk in PMDS, and optimal management and surveillance of PMDS.

Diagnostic value of ultrasound in children with transverse testicular ectopia

OBJECTIVE

The study aimed to investigate the diagnostic value of ultrasound in children's transverse testicular ectopia (TTE).

MATERIALS AND METHODS

We retrospectively studies all TTE cases diagnosed in our hospital from January 2017 to December 2021. All cases were evaluated by ultrasound examination and compared to physical examination and diagnostic laparoscopy results.

RESULTS

This study included 14 TTE patients in total, with a median age was 1.08 years. In the 14 TTE, physical examination found 10 TTE cases, of which nine testes were located in the opposite scrotum, one testis was located in the opposite groin, and the other four testes were not observed by physical examination. All cases were diagnosed by preoperative ultrasound, and nine testes were located in the opposite scrotum, two testes were located in the opposite groin, and three testes were located next to the opposite iliac vessel in the abdominal cavity. Preoperative ultrasound showed the ectopic spermatic cord in six cases (6/14, 42.8%) and persistent Müllerian duct syndrome (PMDS) in one case (1/14, 7%). Diagnostic laparoscopy finally confirmed 14 cases of TTE, which was consistent with preoperative ultrasound, and the coincidence rate was 100% (14/14). Among the 14 cases of TTE, diagnostic laparoscopy showed that 12 cases had ectopic spermatic vessels and vas deferens (12/14, 85.7%), and six cases were associated with PMDS (6/14, 42.8%). When TTE was associated with the ectopic spermatic cord and PMDS, the diagnostic performance of diagnostic laparoscopy was better than that of preoperative ultrasound (P < 0.05). The testis volume of the affected side of TTE was less than that of the contralateral testis (P < 0.05).

CONCLUSION

Ultrasonography is very helpful for the preoperative diagnosis of TTE in children, and it is suitable as a non-surgical method for locating ectopictestis. Preoperative assessment of the exact presence of PMDS is difficult and unclear. This may be related to factors such as pelvic developmental stages in infancy, examination techniques, and atypical imaging findings of PMDS.
