neurofibromatosis 2/headache

Neurocutaneous syndromes are heterogeneous group of disorders with abnormalities of central as well as peripheral nervous system. Neurofibromatosis type II (NF-II) is an autosomal dominant neurocutaneous syndrome rarely diagnosed in pediatric population. Diagnosis is based on clinical history and

Meningioangiomatosis (MA) is a rare, benign hamartomatous lesion found in cerebral cortex and leptomeninges. It occurs mostly in 5 - 15 year old children in form isolated or diffuse; the diffuse form may be associated with neurofibromatosis type 2 (NF2). The sporadic type in the adults is less

A 42-year-old woman complained of tinnitus, hearing loss and headache. Many years ago she had been treated for a vestibular schwannoma and cutaneous neurofibroma. MRI revealed bilateral vestibular schwannomas and multiple meningiomas due to neurofibromatosis type 2.

OBJECTIVE Neurofibromatosis type 2 (NF2) is an infrequent autosomal dominant disease characterised by the appearance of viii nerve schwannomas, meningiomas and ocular abnormalities. Incidence of 1:25,000 and prevalence above 1:80,000 are estimated in general. The objectives of our study were to

OBJECTIVE Bevacizumab for hearing preservation in patients with neurofibromatosis type 2 (NF2) is an emerging practice. We set out to characterize the effectiveness and toxicity of bevacizumab in our patient group. METHODS Case series with chart review. METHODS Tertiary referral

Neurofibromatosis 2 (NF2) results in multiple central nervous system tumours. In this case report, the patient has one vestibular schwannoma, one trigeminal schwannoma and two meningiomas developed before the age of 30. Aiming to treat three targets at one fraction with minimal interaction and

BACKGROUND Neurofibromatosis type 2 (NF2) and schwannomatosis are entities that may, due to the similarity of clinical symptoms, cause diagnostic difficulties. Incidence rate of both diseases is similar and estimated between 1:25,000 and 1:40,000. The genes associated with the development of the

Neurofibromatosis-2 (NF2) is an autosomal-dominant disease, which is characterized by vestibular schwannomas (VSs) (acoustic neurinoma) as well as tumours of the peripheral and central nervous system, demonstrating a variety of expression. A 12-year-old girl presented to us with headache and ataxia

BACKGROUND The pathogenesis of sporadic multiple meningiomas in the patients without history of neurofibromatosis type II remains unclear. We report whole exome sequencing (WES) of 2 metachronous multiple meningiomas of the same patient. CASE REPORT A 39-year-old female had a 5-month history of

A familial or inherited occurrence of von Recklinghausen's disease has been reported hitherto, some of which were associated with intracranial tumors such as gliomas, neurinomas, meningiomas or others. Authers report a family (case 1: father, case 2: son, case 3: daughter) of von Recklinghausen's

A 26-year-old man who had neurofibromatosis type-2 with symptoms of unexplained optic disc edema is reported. Magnetic resonance imaging (MRI) revealed bilateral acoustic schwannomas. Obstructive hydrocephalus, however, was not evident in spite of his severe disc edema and visual loss. After partial

Neurofibromatosis 2 (NF2) is caused by mutations in the NF2 gene predisposing carriers to develop nervous system tumours. Different NF2 mutations result in either loss/reduced protein function or gain of protein function (abnormally behaving mutant allele i.e. truncated protein potentially causing

A family of von Recklinghausen's disease complicated by multiple diverse primary brain tumors was reported. Case 1. The proband, born in 1923, was admitted to the Nagasaki University Hospital on March 11, 1974, for evaluation of headache and hearing loss. Neurological examination disclosed:
