Introduction Bilateral abdominoscrotal hydrocele is a rare entity in childhood. The etiology of abdominoscrotal hydrocele has not been fully clarified. The diagnosis is based on clinical examination, ultrasound and magnetic resonance imaging. The treatment is surgery. Case outline This paper presents an eight-month-old boy who was admitted at the department of pediatric surgery due to bilateral swellings in the scrotum area. The changes were first noticed when he was three months old and the diagnosis of bilateral abdominoscrotal hydrocele was confirmed after the scrotum ultrasound examination. When the patient was six and eight months old, the symptoms have significantly increased, the magnetic resonance of the abdomen and the lesser pelvis was performed, and the bilateral abdominoscrotal hydrocele was successfully treated with inguinal surgery. The operative and postoperative course was uneventful. Conclusion In this paper, we presented a rare form of hydrocele in children, as well as diagnostic evaluation that involved ultrasound and magnetic resonance examination. Surgical treatment by inguinal approach is also presented.
