BACKGROUND AND OBJECTIVES: Decision-making regarding the therapy of vestibular schwannoma (VS) changed over the last decades, during which curative microsurgery has been promoted. Goals of VS microsurgery are: extensive resection, facial nerve (FN) preservation and, in selected cases, hearing preservation (HP). The aim of this study is to evaluate postoperative HP with reference to tumor size in patients operated on with Level Specific (LS)-CE-Chirp® ABR monitoring. PATIENTS AND METHODS: Twentyfive consecutive patients with socially useful hearing (SUH) underwent VS microneurosurgery by retrosigmoid (RS) approach...

BACKGROUND: Frontoethmoidal schwannomas are rare. No case manifesting exertional cerebrospinal fluid (CSF) rhinorrhea has ever been reported to the best of our knowledge. CASE DESCRIPTION: In this report, we describe an extremely rare case of frontoethmoidal schwannoma extending through the olfactory groove (OG) with exertional CSF rhinorrhea as the initial symptom. A 50-year-old woman was presented to our clinic for frequent nasal discharge on exertion. A postcontrast computed tomographic scan demonstrated heterogeneously enhanced tumor from the anterior cranial fossa to the anterior ethmoid sinus...

BACKGROUND: Granular cell tumors are benign lesions that typically occur in the oral cavity, but can also be found in other sites. However, the characteristics of these tumors are unclear. Thus, the present study aimed to investigate the immunohistological characteristics of these tumors of the tongue. METHODS: Seven patients were treated for granular cell tumors of the tongue at our institution during 2003-2017. Paraffin-embedded specimens were available for all cases; thus, retrospective immunohistochemical analyses were performed...

Liponeurocytoma is a very rare tumor classified as grade II (neuronal and mixed neuronal-glial tumors) according to 2016 WHO classification of Tumors of the Central Nervous System. The median age is 50-years-old and the most frequent location is the posterior cranial fossa especially within the cerebellar hemispheres; those arising in the cerebellopontine angle are exceptional. We herein report the clinical, radiological and pathological characteristics of a cerebellopontine angle liponeurocytoma in a 35-year-old woman...

OBJECTIVE: Interdisciplinary work including surgery and additive radiotherapy is often needed for the therapy of tumours. Beneath this, brachytherapy is an important part of the radiotherapy. It was first used over 100 years ago and is in regular use after the development of afterload technology in the early 1970s. Today it is often used in different tumour therapies, for example in soft tissue sarcoma or breast tumours, in order to decrease the risk of local recurrence. Concerning its benefits, higher doses could be used because of the localized effect with equivalent local control rate and less toxicity of treatment...

Facial nerve schwannomas (FNSs) are rare benign tumors arising from the Schwann cells of the sheath of the facial nerve. These tumors may arise anywhere along the course of the facial nerve. Owing to their rarity and nonspecific clinical and radiological presentations, the preoperative diagnosis of FNSs is exceedingly difficult. In this study, we present four cases of histopathologically proven extratemporal schwannomas and a solitary case of intratemporal schwannoma. The purpose of this study was mainly focused on analyzing the imaging findings of extratemporal and intratemporal schwannomas in an effort to better characterize these lesions preoperatively...

Importance: Neurofibromatosis type 2 (NF2) is a devastating genetic condition characterized by the development of multiple tumors of the nervous system. An early diagnosis of individuals with NF2 would facilitate treatment and reduction of disease impact because most severe effects of the disease do not usually develop before adolescence. Little attention has traditionally been paid to dermatological signs in NF2. However, skin plaques are commonly seen in patients with NF2, normally appearing either at birth or early childhood, providing an opportunity for early NF2 detection and testing...

The number of patients receiving cochlear implants and auditory brainstem implants for severe to profound sensorineural hearing loss has rapidly increased. These implants consist of an internal component implanted between the skull and the temporal scalp and an external removable speech processor unit. A small magnet within the internal component is commonly used to hold the external speech processor unit in place. Several cochlear implant models have recently received U.S. Food and Drug Administration and European Economic Area regulatory approval to allow magnetic resonance (MR) imaging examinations to be performed under certain specified conditions...

Facial nerve schwannoma localized in the middle fossa is a rare lesion. We report a case of a facial nerve schwannoma in a 30-year-old male presenting with facial nerve palsy. Magnetic resonance imaging (MRI) showed a 3 cm diameter tumor of the right middle fossa. The tumor was removed using a sub-temporal approach. Intraoperative monitoring allowed for identification of the facial nerve, so it was not damaged during the surgical excision. Neurological clinical examination at discharge demonstrated moderate facial nerve improvement (Grade III House-Brackmann)...

We report a case of low-grade fibromyxoid sarcoma arising within the median nerve. A 31-year-old woman presented with symptoms of carpal tunnel syndrome and an enlarging mass in her right palm over 1 year. MRI demonstrated a mass associated with the right median nerve with solid and cystic components. At surgery, the mass was located within the epineurium, could be bluntly dissected from the nerve fascicles, and was suspected to be a schwannoma. A 3.4 cm, tan-pink, glistening, smooth, homogenous mass was submitted to pathology...

PURPOSE: Chordoma is a low-grade malignant bone tumor derived from embryonic notochord remnants along the axial skeleton. About 50% of chordomas occur in the sacral vertebrae and 35% in the skull base. Most chordomas are extradural and cause extensive bone destruction. Intradural spinal tumors without bone involvement are rare. METHODS: We herein describe the clinical features of a patient with a chordoma as well as the imaging and pathological manifestations of the tumor...

RATIONALE: Renal hybrid oncocytic/chromophobe tumors (HOCTs) are benign tumors containing a mixture of cells with features of chromophobe renal cell carcinoma (CHRCC) and renal oncocytoma (RO). Sporadic HOCT, which means HOCT occurs in patients without Birt-Hogg-Dubé syndrome (BHDS) or renal oncocytosis, is extremely rare. In this article, we would report a new case of a patient with both sporadic HOCT and multiple Schwannomas, which is even rarer than simplex sporadic HOCT. PATIENT CONCERNS: A 48-year-old female was noted with multiple left-kidney masses and a history of multiple Schwannomas...

QUESTION 1: What is the expected diagnostic yield for vestibular schwannomas when using a magnetic resonance imaging (MRI) to evaluate patients with previously published definitions of asymmetric sensorineural hearing loss? TARGET POPULATION: These recommendations apply to adults with an asymmetric sensorineural hearing loss on audiometric testing. RECOMMENDATION: Level 3: On the basis of an audiogram, it is recommended that MRI screening on patients with ≥10 decibels (dB) of interaural difference at 2 or more contiguous frequencies or ≥15 dB at 1 frequency be pursued to minimize the incidence of undiagnosed vestibular schwannomas...
