Neurofibromatosis-2 (NF2) is an autosomal-dominant disease, which is characterized by vestibular schwannomas (VSs) (acoustic neurinoma) as well as tumours of the peripheral and central nervous system, demonstrating a variety of expression. A 12-year-old girl presented to us with headache and ataxia for four months. We examined and found a lump in the right side of her abdomen. On magnetic resonance imaging (MRI) of brain, a bilateral VS at the cerebellopontine (CP) angle was detected, and on computerized tomography (CT) scan and ultrasonography of her abdomen a large retroperitoneal schwannoma was revealed in the right side of her abdomen. At first, the right-sided CP angle tumour and two months later, the left-sided lesion was operated. After some days, she became mute and incontinent, and was found to have hydrocephalus on CT scan. We introduced a ventriculoperitoneal shunt. Then we operated the abdominal lump, which was histologically proven as schwannoma. The association of these three tumours is rare and untiring surgical approaches made her better. The patient recovered well except bilateral mild facial and vestibulocochlear deficit.
