Ovarian tumors are rare in childhood and adolescent age. A 14-year-old girl presented with abdominal distention and mild cyclical abdominal pain since 3 months ago. There was an abdominal distention, and huge firm mass was palpated from pelvis to epigastric region. Abdominal ultrasonography revealed normal uterus and large multiloculated adnexal mass with multiple fine septations.
