Ultrasonography Crucial in Preoperative Diagnosis and Rescue of Ectopic Testis with Torsion: Case Report
Japan: A recent case study published in Cureus highlights the critical role of ultrasonography in diagnosing an ectopic testis with torsion, highlighting its effectiveness in differentiating between several conditions that present with inguinal swelling. This case illustrates the significant diagnostic value of ultrasonography in managing complex scenarios involving testicular abnormalities.
Diagnosing a twisted ectopic testis, a rare condition, presents a significant challenge, particularly when the testis is not located in the scrotum. Failure to diagnose this condition preoperatively can lead to testicular necrosis. The clinical case reported by Takayuki Fujii, Department of Pediatric Surgery, Kagawa University, Takamatsu, Japan, and colleagues highlights the successful use of ultrasonography in diagnosing and rescuing a twisted ectopic testis before surgery.
The case concerns a patient, a generally healthy 13-year-old boy, who was referred to the Urology Department after experiencing a painless swelling in the left inguinal region for two weeks, followed by mild exercise-induced pain in the same area one week before his referral. The condition did not worsen despite the persistent mild pain.
Upon examination, a mildly tender swelling was observed in the left inguinal region, and the left half of the scrotum was empty. The right testis was found to be normal in size and position. Ultrasonography was employed to further investigate the issue. The imaging revealed that the left spermatic cord was present within the inguinal canal and exhibited spiral twisting. The left testis was positioned above the inguinal canal and appeared normal in echogenicity but was notably smaller than the right testis (right testis: 41 × 28 × 16 mm; left testis: 18 × 18 × 8 mm). Power Doppler ultrasound showed normal blood flow to the left testis.
