Encysted spermatic cord hydrocele: A case series

Abstract

Introduction and importance: Encysted spermatic cord hydrocele is a rare anomaly characterized by obstruction of processus vaginalis closure. Clinically, it presents as a swelling in the inguinal region extending to the upper scrotum and does not communicate with the peritoneal cavity. It is often mistaken for indirect inguinal hernias, inguinal lymphadenopathy, undescended testis, and primary tumors of the cord in infants and children, making the diagnosis challenging.

Case presentation: We report the cases of five male patients aged nine months to 12 years who presented with painless swelling on the right side of the scrotal region. Physical examination revealed firm masses in the right inguinal region with positive transillumination, negative cough impulse tests, and irreducibility. Inguinal and scrotal ultrasonography showed an anechoic cystic lesion with thin walls, without any signs suggestive of a hernia. Patients were diagnosed with encysted spermatic cord hydrocele and advised to undergo cyst excision. The postoperative periods were uneventful, and expected recovery was observed at one-week and one-month follow-ups.

Clinical discussion: Encysted spermatic cord hydroceles are rare causes of painless inguinal swelling. The medical history and clinical findings can be used to establish a diagnosis, which can be confirmed using ultrasonography. Management depends on differentiating between spermatic cord hydrocele and scrotal hydrocele and involves considering the type. Treatment options range from conservative measures to surgery, particularly for non-communicating hydroceles that persist beyond 12-18 months or enlarge in size.

Conclusion: Encysted hydrocele of the cord is rare and is often mistaken for indirect inguinal hernias in infants and children. This similarity makes the diagnosis challenging and necessitates vigilance from clinicians. Surgical intervention results in optimal outcomes, especially in cases where the hydrocele persists beyond 12-18 months or with size progression.
