Neurofibromatosis type 1 (NF1, von Recklinghausen’s disease) is known to be the neurocutaneous disease, called phacomatoses. It is one of the most common inherited autosomal dominant disorder, occurring with a frequency of approximately 1:3000 births. The typical symptoms of NF1 are café au lait spots, axillary, groin freckling, neurofibromas and Lisch nodules on the irises. In patients also more frequently than in the general population is observed occurrence of benign and malignant tumours. The most common tumour in the case of NF1, approximately in 15-20% of patients, is visual pathway glioma, known as capillary astrocytoma, which involves visual nerves and/or the optic chiasm and leads to visual field loss. The visual pathway gliomas grow slowly, sometimes can be asymptomatic and rarely take an aggressive form, and only one third of patients require surgery. Among other cancers in patients with NF1 we also have: sarcoma of peripheral nerves, striated cell sarcoma, a pheochromocytoma, carcinoid of the duodenum, nonlymphocytic leukaemia. Other symptoms of NF1 include dysplasia and bone deformities, macrocephaly, short height, mental retardation, impaired visual-spatial orientation, poorer memory, dyslexia, and epilepsy. We present a case of 19-year-old patient diagnosed with neurofibromatosis type 1 with coexisting optic chiasm glioma and drug resistant epilepsy.
