Abstract
OBJECTIVE Onset of symptoms in severe sporadic neurofibromatosis type 2 (NF2) is typically within childhood; however, there is poor awareness of presenting features in young children, potentially resulting in delayed diagnosis and poorer outcome. We have reviewed presentation of sporadic paediatric NF2 to raise awareness of early features, highlighting those requiring further investigation. DESIGN Patients diagnosed with NF2 at age ≤16 and seen between 2012 and 2015 were notified via the British Paediatric Neurology Surveillance Unit or identified through the English NF2 service. RESULTS Epidemiological data estimate that 1 in 110 611 births are affected with childhood-onset NF2. Notes of 32 patients with sporadic NF2 were reviewed. Of those presenting under the age of 5, 89% (17/19) had ocular, 74% (14/19) dermatological and 58% (11/19) neurological signs; in 84% (16/19) features were multisystemic. Sixty-six per cent (21/32) had ≥1 atypical feature, including cerebellar hypoplasia in three cases (9%) and focal cortical dysplasia in five out of seven seizure-related presentations. Five cases presented with a sometimes transient or intermittent cranial nerve mononeuropathy. The mean delay to diagnosis was 3.16 years; in eight cases (25%) this exceeded 6 years. Most significant delay occurred in mononeuropathy, ophthalmological and/or seizure presentations, with a mean delay of 3, 4.5 and 6 years, respectively. Eighty-four per cent (27/32) of cases needed intervention in childhood. CONCLUSIONS All non-vestibular schwannoma NF2 presentations in childhood had significant diagnostic delay. We emphasise the importance of detailed assessment of skin and eyes in unusual presentations and propose an aide to prompt timely referral to specialist services.

Bevacizumab in neurofibromatosis type 2 (NF2) related vestibular schwannomas: a nationally coordinated approach to delivery and prospective evaluation. Neurooncol Pract 2016; 3:281-289.

Abstract
Background NF2 patients develop multiple nervous system tumors including bilateral vestibular schwannomas (VS). The tumors and their surgical treatment are associated with deafness, neurological disability, and mortality.Medical treatment with bevacizumab has been reported to reduce VS growth and to improve hearing. In addition to evaluating these effects, this study also aimed to determine other important consequences of treatment including patient-reported quality of life and the impact of treatment on surgical VS rates. Methods Patients treated with bevacizumab underwent serial prospective MRI, audiology, clinical, CTCAE-4.0 adverse events, and NFTI-QOL quality-of-life assessments. Tumor volumetrics were classified according to the REiNs criteria and annual VS surgical rates reviewed. Results Sixty-one patients (59% male), median age 25 years (range, 10-57), were reviewed. Median follow-up was 23 months (range, 3-53). Partial volumetric tumor response (all tumors) was seen in 39% and 51% had stabilization of previously growing tumors. Age and pretreatment growth rate were predictors of response. Hearing was maintained or improved in 86% of assessable patients. Mean NFTI-QOL scores improved from 12.0 to 10.7 (P < .05). Hypertension was observed in 30% and proteinuria in 16%. Twelve treatment breaks occurred due to adverse events. The rates of VS surgery decreased after the introduction of bevacizumab. Conclusion Treatment with bevacizumab in this large, UK-wide cohort decreased VS growth rates and improved hearing and quality of life. The potential risk of surgical iatrogenic damage was also reduced due to an associated reduction in VS surgical rates. Ongoing follow-up of this cohort will determine the long-term benefits and risks of bevacizumab treatment.
