Abstract

Cerebellopontine angle tumors represent 6 to 10% of all proliferative lesions in the central nervous system. The most frequently encountered in this area are acoustic neuromas (80–90%), cholesteatoma (6%) and meningiomas (6%). Neuromas usually occur in women between the ages of 50–60 years. In 95% of cases these tumors are unilateral. Cerebellopontine angle tumors in the pediatric population are rare, and their occurrence is closely linked to genetically determined neurofibromatosis type 2, whose prevalence is 1/40000–50000. More than 95% of them are diagnosed with Schwannomas. We present the case of a 5-year-old boy, diagnosed in the our Department of Otolaryngology due to progressive unilateral hearing loss. In the pediatric and neurological examination, there were no significant deviations from the normal condition. The patient was otolaryngologically examined and had audiological diagnostics. We diagnosed deafness of the left ear, both in the subjective and objective studies. MRI examination revealed the presence of a solid tumor of 20 mm diameter in the left cerebellopontine angle, probably an acoustic neuroma. Cerebellopontine angle tumors in children are very uncommon and despite the lack of signs of neurofibromatosis type 2, they require precise genetic diagnosis.
