Graves disease is rarely complicated with cerebrovascular steno-occlusive diseases. Previous studies have suggested several hypotheses for this occurrence, including excess thyroid hormone, which stimulates the sympathetic nervous system, which in turn causes an abnormal hemodynamic response with consequent atherosclerotic changes, and antithyroid antibodies cause local vascular inflammation in patients with Graves disease. However, radiological findings of vasculitis in patients with Graves disease and cerebral infarction remain less known...

BACKGROUND: Intracranial carotid sympathetic plexus schwannoma (CSPS) is extremely rare; thus differential diagnostic criteria, optimal surgical strategies, and even a precise definition are lacking. Here we describe a case of CSPS and propose a definition and classification for previously reported cases. CASE DESCRIPTION: A 54-year-old male presented with hypacusis and abducens nerve palsy. Radiological examinations revealed a well-enhanced mass at the right medial temporal base with erosion of the petrous apex and intact perilesional cortical bone...

OBJECTIVE Patient-reported outcomes are increasingly used in studies of vestibular schwannoma (VS); however, few studies have examined self-evaluated facial nerve function and its relation to physician-reported outcomes. The primary objective of this study was to compare patient self-evaluations of facial disability with physician-evaluated facial nerve status and with self-evaluations of a healthy control group. The second objective was to provide insight into the controversial subject of the optimal initial management of small- and medium-sized VSs; consequently, the authors compared patient-reported facial nerve disability following treatment via observation (OBS), Gamma Knife surgery (GKS), or microsurgery (MS)...

OBJECTIVE The aim of this study was to reappraise long-term treatment outcomes of stereotactic radiosurgery (SRS) for vestibular schwannomas (VSs). The authors used a database that included patients who underwent SRS with a unique dose-planning technique, i.e., partial tumor coverage designed to avoid excess irradiation of the facial and cochlear nerves, focusing on tumor control and hearing preservation. Clinical factors associated with post-SRS tumor control and long-term hearing preservation were also analyzed...

The present study was undertaken to evaluate real probability and pattern of cervical occult lymph node metastases (OLNM) in primary parotid carcinoma (PPC). We carried out a retrospective analysis of 66 patients treated in years 1992-2010 due to PPC, who underwent elective neck dissection (END). In search of risk factors for OLNM, we analysed the following parameters: age, sex, pT-Status, tumour size, skin invasion, facial nerve palsy, tumour fixation, extraparotid extension, localization, grade, histology, intra/periparotid LN metastases (IPLNM)...

BACKGROUND: Although many factors have been found to be involved in recovery from Bell's palsy, no study has investigated the association between recovery from Bell's palsy and obesity. This study therefore evaluated the association between recovery from Bell's palsy and body mass index (BMI). METHODS: Subjects were classified into five groups based on BMI (kg/m2). Demographic and clinical characteristics were compared among these groups. Assessed factors included sex, age, time from paralysis to visiting a hospital, presence of comorbidities such as diabetes mellitus and hypertension, degree of initial facial nerve paralysis by House-Brackmann (H-B) grade and neurophysiological testing, and final recovery rate...

Vestibular schwannoma treatment with stereotactic radiosurgery (SRS) carries a risk of facial nerve (CNVII) palsy that is lower than that with microneurosurgery. The results of hemihypoglossal-facial nerve anastomosis (HHFA) have not been described yet in CNVII palsy after failed stereotactic radiosurgery (SRS). Here we report a case series of the first four consecutive patients (three women; average age 58.5, age range: 46-74), who underwent HHFA due to failed SRS. All patients were admitted because of progressive peripheral facial nerve palsy...

INTRODUCTION: Intracranial malignant peripheral nerve sheath tumors are an extremely rare pathology with a high morbidity and mortality. Epidemiological, clinical and prognostic data are scarce and with little certainty in the literature. The aim of this paper is to report for first time in English literature, the case of a patient with type 1 neurofibromatosis, who presented a malignant peripheral nerve sheath tumor that involved the left glossopharyngeal, vagus and spinal nerves with intracranial and extracranial extension through jugular foramen and systemic metastases...

Congenital facial palsy (CFP) is clinically defined as facial palsy of the seventh cranial nerve which is present at birth or shortly thereafter. It is generally considered to be either developmental or acquired in origin. Facial palsy of developmental origin is associated with other anomalies including those of pinna and external auditory canal, which range from mild defects to severe microtia and atresia. We report a 2-day-old male newborn that had right CFP with bilateral anotia and atresia of external auditory canals which is rare...

Distant metastases are relatively common in breast cancer, but spread to the head and neck region is uncommon and can be diagnostically challenging. Pathology databases of two academic hospitals were searched for patients. The diagnoses were by morphologic comparison with the primary breast specimen (when available) or through the use of immunohistochemical stains characteristic of breast carcinoma (cytokeratin 7, mammaglobin, GCDFP15, and/or GATA3 positive-excluding new primary tumors at the respective head and neck sites)...

Unruptured posterior communicating artery (PCOM) aneurysms can be difficult to diagnose and, when large (≥ 7mm), represent a substantial risk to the patient. While most unruptured PCOM aneurysms are asymptomatic, when symptoms do occur, clinical manifestations typically include severe headache (HA), visual acuity loss, and cranial nerve deficit. This case report describes an atypical initial presentation of a large unruptured PCOM aneurysm with symptoms mimicking trigeminal neuralgia, without other associated cranial nerve palsies or neurologic deficits...

PURPOSE: To evaluate the inter- and intraobserver reliability of the CADS score, a previously described facial nerve grading instrument for ophthalmic grading of facial nerve palsy. METHODS: This is a cross-sectional validation study. Two clinicians independently assessed and graded each patient on the same day, masked to each other's grading. Four parameters are assessed in the CADS scale: Cornea (0-3, ±a), static Asymmetry (0-2), Dynamic function (0-3), and Synkinesis (0-2)...

BACKGROUND: Bell's palsy is characterised by an acute onset of unilateral, lower motor neuron weakness of the facial nerve in the absence of an identifiable cause. Establishing the correct diagnosis is imperative and choosing the correct treatment options can optimise the likelihood of recovery. OBJECTIVE: This article summarises our understanding of Bell's palsy and the evidence-based management options available for adult patients. DISCUSSION: The basic assessment should include a thorough history and physical examination as the diagnosis of Bell's palsy is based on exclusion...

Kernohan-Woltman notch phenomenon (KWNP) is a false localising sign which may still cause diagnostic confusion. It was first described by Kernohan and Woltman in 1929, through post-mortem studies on 297 patients following cases of false localisation. They proposed that raised intracranial pressure causes uncal herniation, which can compress the contralateral cerebral peduncle against the tough tentorium, manifesting as hemiparesis ipsilateral to the primary brain lesion. A number of case reports have been written since the original description of this phenomenon, primarily secondary to intracranial bleeds, and little has been written about long-term outcome of patients who develop KNWP...

Facial nerve schwannoma is a rare intracranial tumor. Treatment for this benign tumor has been controversial. Here, we report a case of extracranial facial nerve schwannoma treated successfully by hypo-fractionated CyberKnife (Accuray, Sunnyvale, CA) radiosurgery and discuss the efficacy of this treatment. A 34-year-old female noticed a swelling in her right mastoid process. The lesion enlarged over a seven-month period, and she experienced facial spasm on the right side. She was diagnosed with a facial schwannoma via a magnetic resonance imaging (MRI) scan of the head and neck and was told to wait until the facial nerve palsy subsides...
