Introduction: Vaginal hydrocele is an amber-colored, sterile collection found between the parietal and visceral testis. It is said to be giant when it is larger than the patient's skull or when it contains more than two liters of liquid. Objective: To report our method and the result of the surgical treatment. Observation: The authors reported an observation of a 50-year-old patient who consulted for a painless large left bursa. Clinical and paraclinical investigations, in particular scrotal ultrasound, have made it possible to diagnose a giant hydrocele of the vagina. The patient had surgical treatment which consisted of resecting of the vagina with hemostatic suture of the resected vaginal slice. The post-operation effects were not complicated. After a six-month setup, we did not notice any recurrence. Conclusion: Resection of the vagina with hemostatic suture of the resected vaginal slice in case of giant hydrocele could certainly give good results.
