“…Acoustic neuromas have been reported, often in the setting of familial neurofibromatosis type II. Fewer than 30 sporadic cases have been described [25,26]. As in adults, older children sometimes initially present with neural features such as disproportionately poor speech discrimination [25].…”

“…Very rarely however, VS may occur sporadically in a child without any features of NF2. [14] Acoustic schwannomas associated with NF-2 account for 2%–4% of all acoustic schwannomas with the mean patient age being younger than that of sporadic schwannomas. [2] Sporadic VS usually presents with sensorineural hearing loss (98%), tinnitus (70%), disequilibrium or vertigo (67%), and headache (32%).…”

“…However, most cases in the pediatric age group are associated with NF2 and sporadic cases are rare. [1] Patients with VS usually present with sensorineural hearing loss (98%), tinnitus (70%), disequilibrium or vertigo (67%), and headache (32%). Hemorrhage is uncommon in VS: only less than 50 cases have been reported in the literature with almost all belonging to the adult age group.…”

Vestibular schwannomas (VSs) are tumors that commonly occur in the eighth cranial nerve. They are usually associated with type 2 neurofibromatosis. They are uncommon in children, and sporadic cases of pediatric VS are even rarer. In general, VSs are benign lesions with less than 1% chance of intratumoral hemorrhage. Adult cases of hemorrhage in VS are well documented. We present the first pediatric case of intratumoral hemorrhage in VS in the absence of any features of NF in an 11-year-old child who complained of holocranial headache and sensorineural hearing loss in the left ear. We further discuss the pathogenesis and clinical features, and review the literature of intratumoral hemorrhage in patients of VS.

“…The patient gradually recovered full function. Mazzoni et al (4) concluded that it is easier to preserve hearing in children than in adults. However, the tumor size was small in most of their patients, with an average diameter of 2.15 cm.…”

ABSTRACT(approximately 0.2% of all cases reported in the last 20 years in Beijing Tiantan Hospital). █ mATERIAl and mEThODS PatientsTen pediatric patients (6 male and 4 female patients) who were admitted from January 1994 to December 2014 and diagnosed with unilateral vestibular schwannomas were █ INTRODUCTION V estibular schwannomas, which originate from the vestibular division of cranial nerve VIII, occur more often in adults than children. Identification of a sporadic or non-neurofibromatosis type 2 vestibular schwannoma in a child is extremely rare (1-7). When a vestibular schwannoma is found in a child, neurofibromatosis should be the first differential diagnosis. We reviewed 10 cases involving <16-yearold patients without clinical evidence of neurofibromatosis AIm: We investigated the clinical presentation and management issues of unilateral vestibular schwannomas in childhood without evidence of neurofibromatosis. mATERIAl and mEThODS: Ten pediatric patients with unilateral vestibular schwannoma and no evidence of neurofibromatosis were treated by the senior author at Tiantan Hospital from January 1994 to December 2014. The clinical manifestations, neuroimaging findings, treatment methods, and therapeutic results were retrospectively reviewed. RESUlTS:The study included 6 male and 4 female patients. The mean age of the patients was 13.9 years (range, 11-15 years). Common clinical features included increased intracranial pressure, hearing loss, and ataxia. The median diameter of the tumors was 5.15 cm. Gross total resection was achieved in 9 of 10 patients via a suboccipital retrosigmoid approach, and the perioperative mortality rate was 10%. The follow-up period ranged from 1 to 12 years. One patient with facial nerve injury recovered to HouseBrackmann grade I postoperatively, 5 to grade II-III, and 2 to grade IV-V. Only 1 patient had preserved hearing. CONClUSION:The clinical features of pediatric vestibular schwannomas are different from those of adult vestibular schwannomas, and cranial nerve preservation in children is more difficult. When a child presents with hearing loss as well as cognitive disability, a vestibular schwannoma should be highly suspected. Hypervascular vestibular schwannomas in childhood should be managed by multistaged surgeries.
