Objective Neurofibromatosis 2 (NF2) is a neuro-oncologic condition that presents with bilateral vestibular schwannomas of the cerebellopontine angle (CPA). Voice and swallowing impairment can occur from direct involvement or compression of the vagus nerve or as the result of surgical excision of CPA tumors. The objectives in this study are to (1) assess the prevalence of voice and swallowing impairments and (2) analyze the effects of vagal dysfunction in patients with NF2. Study Design Cross-sectional. Setting Academic tertiary care center...

Carotid splaying, also known as the Lyre sign, is a widening of the carotid bifurcation due to the displacement of the internal carotid artery and the external carotid artery just distal to the point of divergence. This phenomenon is classically exhibited by highly vascularized carotid body tumors and, in rare cases, by cervical sympathetic chain schwannomas. Demonstration of the Lyre sign by a cervical vagal neurofibroma, however, is a unique occurrence that has not been previously documented in the literature...

INTRODUCTION: Tumours of the parapharyngeal space are rare. Only 0.5% of head and neck tumours occur in this space. Surgical excision of parapharyngeal space lesions is challenging because of the anatomical complexity of the area. PRESENTATION OF CASE: A 31-year-old male patient was referred by his general dental practitioner for removal of lower wisdom teeth due to multiple episodes of pericoronitis. At the initial examination, an incidental finding was made of a large fluctuant posterior oropharyngeal swelling...

BACKGROUND: We present a case of a cervical schwannoma, likely originating from the pharyngeal plexus of the vagal nerve. The lesion masqueraded as a thyroid nodule and magnetic resonance imaging (MRI) assisted in preoperative diagnosis. We review the radiographic characteristics of nerve sheath tumors on MRI as well as the diagnostic cytologic stains which can enhance the possibility of a correct preoperative diagnosis. CASE: We describe a 60-year-old female with dysphagia and a neck mass consistent with a nodular goiter...

BACKGROUND: Neuroendocrine tumors of the neck are rare swellings, which constitute about 0.03% of all tumors. Most are sporadically arising paragangliomas. Over 50% arise from the carotid bodies and pose difficulties in diagnosis and surgical management, which may result in disabling complications. OBJECTIVE: To determine the diagnostic, surgical, and postoperative challenges, and how to overcome them, in the management of neuroendocrine tumors of the neck. STUDY DESIGN: Descriptive case series...

Background Schwannomas are rare benign tumors originating from the perineural cells forming the myelin layer in the peripheral nervous system (PNS). While well established therapeutic concepts exist for intracranial schwannomas, there is a lack of consistent clinical standards for extracranial schwannomas. Method This retrospective study describes the clinical pathway of 20 patients with histologically proven extracranial schwannomas of the head and neck. The diagnostic and therapeutic strategies for schwannomas are discussed with special emphasis on localization and functional outcome...

Schwannomas arising from cervical vagus nerve is an extremely rare benign neoplasm. The majority of patients present with insidiously growing lateral neck mass without neurological deficit. We report a case of symptomatic cervical vagal nerve schwannoma in a 32-year-old female. Complete surgical resection is the treatment of choice. However, anesthetic management of these tumors can be challenging. We describe here the complications experienced during the management of the patient.

Neurogenic neoplasms resulting from autonomic nerves are considerably rare. In this paper, we report a case of a 41-year-old woman with composite tumor of synchronous ganglioneuroma and schwannoma in the vagal inferior ganglion. Ultrasonography and computed tomography showed a well-defined mass, which extruded from the internal and external carotid arteries. Two tumors were closely attached but with an evident boundary. The small tumor was composed of spindle cells and numerous mature ganglion cells, and the large one consisted entirely of differentiated neoplastic Schwann cells...

Cervical vagal schwannoma is a rare entity among lesions presenting as a neck mass. They are usually slow-growing benign lesions closely associated with the vagus nerve. They are usually solitary and asymptomatic. Multiple schwannomas occurring in patients without neurofibromatosis (NF) are rare and have recently been referred to as schwannomatosis. Here, we present a case of a neck mass that had imaging features suggestive of vagal schwannoma and was operated upon. Intraoperatively, it was discovered to be a case of multiple vagal cervical schwannoma, all directly related to the right vagus nerve, and could be resected from the nerve in toto preserving the function of the vagus nerve...

The parapharyngeal space extends from the nasopharynx to the oropharynx. It is bordered medially by the pharyngeal wall and the constrictor pharyngis muscles, and laterally by the mandible. One distinguishes between a pre- and a poststyloid space. Tumors of the parapharyngeal space are rare and represent less than 1 % of all head and neck neoplasms. Benign (70-80 %) as well as malignant (20-30 %) tumors arise from different structures of the parapharyngeal space, mainly from salivary glands and nerve structures...

We describe the case of a 37-year-old man with a slowly enlarging neck lump and compressive symptoms. He presented to a separate institution 10 years prior where an observational approach was advocated. Following preoperative investigations and embolization, an 11cm vagal schwannoma was excised and vagus nerve was sacrificed. Although conservative management is appropriate for a select patient population, surgical excision is treatment of choice for cervical neurogenic tumours and paraganglionomas and must be considered in young patients or rapidly expanding tumours to avoid compressive symptoms, as in this case...

Among the parapharyngeal tumours, salivary gland tumours are the commonest, followed by schwannomas, which are slow growing benign tumours. Half of the parapharyngeal schwannomas originate from the vagus. Complete surgical excision is the treatment of choice. We hereby present two cases of parapharyngeal schwannomas, one which had presented as an intraoral mass and the other as a swelling in the neck. The first case, a 57-year-old female patient complained of a slowly increasing swelling in the left side of the throat since 3 months, associated with pain and dysphagia...

OBJECTIVE Vagus nerve and sympathetic chain cervical schwannomas (VNCSs and SCCSs) are benign nerve sheath tumors that arise in the head and neck. Despite similar presentations that make accurate preoperative diagnosis more difficult, the potential for morbidity following resection is significantly higher for patients with VNCS. Therefore, the authors analyzed a retrospective case series and performed a comparative analysis of the literature to establish diagnostic criteria to facilitate more accurate preoperative diagnoses...

A 44-year-old woman was referred to our department with a mediastinal tumor detected by computed tomography performed as a preoperative examination for cervical cancer. There was a 32 mm solid mass in the area surrounded by the descending thoracic aorta, esophagus, left atrium, left lower lobe, and mediastinal pleura. The tumor was removed thoracoscopically. The mass was regarded as a neurogenic tumor arisen from the branch of the vagus nerve. Neither symptoms of postoperative neurological disorders nor signs of recurrence have been noted to date...

BACKGROUND: Under the definition "glomus tumors" are often erroneously enclosed neoplasms that are absolutely unlike for origin, location, and behavior. Glomus tumors (GTs) are small but extremely painful skin tumors of mesenchymal origin. GTs derive from the neuromyoarterial glomus in adults of middle-age and are generally benign. Due to their small size, diagnosis is often difficult and patients harboring these tumors usually consult many physicians, including sometimes neurosurgeons...

A 51-year-old male who had received hemodialysis twice a week was referred to our hospital for a further examination of bloody pleural effusion in the right chest. He has been suffering from a fever and cough for 2 months. Chest computed tomography and magnetic resonance imaging revealed a pleural effusion in the right pleural cavity and posterior mediastinal tumor in paravertebral lesion. Chest drainage was performed, and cytological diagnosis did not show malignant findings. To make a definite diagnosis and treatment, surgical resection was carried out...

Cervical vagal schwannoma is a benign, slow-growing mass, often asymptomatic, with a very low lifetime risk of malignant transformation in general population, but diagnosis is still a challenge. Surgical resection is the treatment of choice even if its close relationship with nerve fibres, from which it arises, threats vagal nerve preservation. We present a case report and a systematic review of literature. All studies on surgical resection of cervical vagal schwannoma have been reviewed. Papers matching the inclusion criteria (topic on surgical removal of cervical vagal schwannoma, English language, full text available) were selected...

A 59-year-old woman presented with a 1-year history of dysphagia. She suffered from a large mediastinal mass obstructing trachea and bilateral main bronchus, which led to dyspnea and disturbed consciousness. Immediate intubation and surgery was required. A solid tumor that included esophagus and right vagal nerve, and adhered to the membranous part of the bronchus was found. However, the tumor could be resected en bloc and the patient has been free from recurrence. Pathologically, the tumor exhibited proliferative spindle cells and was diffusely positive for S-100 protein...
