The abdominoscrotal hydrocele in the infant – case report

BACKGROUND An abdominoscrotal hydrocele (ASH) is a rare lesion and should be considered in the differential diagnosis of abdominal cystic lesions in boys. CASE REPORT We report a case of a 4-month-old boy with a thin-walled, anechoic cystic abdominal mass in ultrasound (US) examination. As the size of the lesion increased in follow-up US after one month, computed tomography (CT) was performed. CT demonstrated a communication between a cystic mass in the abdomen and a right scrotal hydrocele - an abdominoscrotal hydrocele (ASH). The patient had no symptoms and was observed by means of US examination. After the next 4 months, the size of the ASH decreased remarkably. CONCLUSIONS This rare entity should be considered in differential diagnosis of cystic abdominal masses in boys. Spontaneous resolution of ASH is rare, but asymptomatic patients can be followed up before surgery.
