Optic pathway gliomas (OPG) are the predominant intracranial tumours associated with neurofibromatosis type 1 (NF1). The aim of this study was to evaluate the prevalence and the outcome of OPG in 200 NF1 patients (122 males and 78 females, aged 1-25 years) followed up to 16 years (mean of 6 years). METHODS: All children were evaluated by a detailed physical, neurological and ophthalmological examination. Fifteen out of 200 (7.5%) of these patients (7 males, 8 females) were identified with evidence of optic pathway tumours. RESULTS: Nine children had symptoms such as endocranial hypertension, seizures, headache; 4 patients only showed anomalies at ophthalmological examination; 2 patients had no symptoms or signs. All children had evidence of optic pathway tumour on magnetic resonance imaging. Three had a prechiasmal tumour, 2 had a chiasmal tumour, 1 had prechiasmal/chiasmal tumour, 2 had a prechiasmal/chiasmal and postchiasmal tumour, 2 had a chiasmal and postchiasmal tumour, 4 had a massive involvement of the optic system, 1 child exhibited a bilateral involvement of the optic nerves with additional impairment of the chiasm. Four patients had partial and/or subtotal spontaneous regression. CONCLUSIONS: Because optic pathway tumours arise in children younger than 6 years of age, all NF1 children should undergo yearly ophtalmologic examination and growth assessment to monitor signs of precocious puberty

Abstract

Optic pathway gliomas (OPG) are the predominant intracranial tumours associated with neurofibromatosis type 1 (NF1). The aim of this study was to evaluate the prevalence and the outcome of OPG in 200 NF1 patients (122 males and 78 females, aged 1-25 years) followed up to 16 years (mean of 6 years). METHODS: All children were evaluated by a detailed physical, neurological and ophthalmological examination. Fifteen out of 200 (7.5%) of these patients (7 males, 8 females) were identified with evidence of optic pathway tumours. RESULTS: Nine children had symptoms such as endocranial hypertension, seizures, headache; 4 patients only showed anomalies at ophthalmological examination; 2 patients had no symptoms or signs. All children had evidence of optic pathway tumour on magnetic resonance imaging. Three had a prechiasmal tumour, 2 had a chiasmal tumour, 1 had prechiasmal/chiasmal tumour, 2 had a prechiasmal/chiasmal and postchiasmal tumour, 2 had a chiasmal and postchiasmal tumour, 4 had a massive involvement of the optic system, 1 child exhibited a bilateral involvement of the optic nerves with additional impairment of the chiasm. Four patients had partial and/or subtotal spontaneous regression. CONCLUSIONS: Because optic pathway tumours arise in children younger than 6 years of age, all NF1 children should undergo yearly ophtalmologic examination and growth assessment to monitor signs of precocious puberty
