Background: Epididymo-orchitis is a common pediatric urological emergency, which can typically be managed conservatively with antibiotics. However, if symptoms persist or worsen without an obvious cause, ultrasound evaluation is recommended and surgical exploration may be required.
Case presentation: We report a case of rapidly progressing epididymo-orchitis in a child, leading to testicular ischemia within one day. Intraoperatively we identified that high-tension tunica vaginalis caused compression of the swollen testis, leading to ischemia. After incision and decompression, partial blood flow was restored. However, at follow-up, the affected testicle was significantly reduced in size and hardened, with central ischemia.
Conclusion: In extremely rare cases, epididymo-orchitis can lead to ischemic necrosis of the testicle. This may be due to early spermatic cord compression, for example, by an enlarged thecal tunica vaginalis sac or epididymis. Early invasive treatment can provide better opportunities to preserve the testicles.
