Neurofibromatosis type 2 (NF2) is a rare autosomal dominant neurocutaneous disorder (phakomatosis) manifesting as a development of multiple CNS tumors.Unlike neurofibromatosis type 1 (NF1), it is not associated with neurofibromas. Usually, three types of neurofibromas occur in this disorder and are distinguished on the basis of their gross and microscopic appearances. Cognitive disability is the commonest neurological symptom described in children with this disease, and it does not improve in adulthood 1. It is important to consider that NF1 has a much earlier age of onset than schwannomatosis and NF2, with approximately 50% of patients meeting the diagnostic criteria for NF1 by the age of 1 year and approximately 97% meeting the criteria by the age of 8 years 10.
