A hydrocele is a fluid collection within the tunica vaginalis of the scrotum or along the spermatic cord. [1] These fluid collections may represent persistent developmental connections along the spermatic cord or an imbalance of fluid production versus absorption. In rare cases, similar fluid collections can develop in females along the canal of Nuck.
In endemic tropical regions, scrotal hydrocele may occur in males of any age as a result of filariasis, especially from Wuchereria bancrofti infection.[5] See Filarial Hydrocele.
