OBJECTIVE: Ramsay Hunt syndrome (RHS) and Bell's palsy (BP) are typically known as facial nerve motor syndromes and are primarily unilateral. The aim of this study was to challenge this assertion because both conditions are also known to be associated with viruses that typically affect several nerves. METHODS: Ten participants with RHS, 12 with BP, all clinically unilateral, and 12 healthy controls were prospectively enrolled. Electrogustometric thresholds were measured bilaterally in the areas of the chorda tympani, the glossopharyngeal, and the major petrosal nerve...

A 2-year-old male, intact Boxer was referred for chronic diarrhea, hyporexia, labored breathing, weakness and elevated creatine kinase, and alanine aminotransferase activities. Initial examination and diagnostics revealed a peripheral nervous system neurolocalization, atrial premature complexes, and generalized megaesophagus. Progressive worsening of the dog's condition was noted after 36 h; the dog developed aspiration pneumonia, was febrile and oxygen dependent. The owners elected humane euthanasia. Immediately postmortem biopsies of the left cranial tibial and triceps muscles and the left peroneal nerve were obtained...

Hypoglossal nerve palsy (HNP) is a common finding in neurologic diseases when associated with other cranial nerve palsies or further pathology and exhibits characteristic clinical manifestations, including unilateral atrophy of the musculature of the tongue. It occasionally appears as the initial or solitary sign of an intracranial or extracranial space-occupying lesion, head or neck injury, or vascular abnormality of the internal carotid artery. There are few cases of idiopathic isolated unilateral HNP, which should be diagnosed through exclusion...

BACKGROUND AND AIM: Trigeminal neuralgia (TN) is a rare orofacial disorder characterized by severe unilateral paroxysmal pain in the region of the fifth cranial nerve. Clinical guidelines recommend carbamazepine (only US Food and Drug Administration-approved drug for TN) and oxcarbazepine as first-line therapies. We utilized the US Truven Health MarketScan database to examine treatment patterns among patients with TN. METHODS: Included patients were aged ≥18 years, newly diagnosed with TN (≥2 TN diagnoses ≥14 days apart; no diagnosis in the prior year), continuously enrolled 1 year pre-index, with ≥3 years' follow-up post-index...

Cranial nerve involvement frequently involves neuron damage and often leads to psychiatric disorder caused by multiple inducements. Lurasidone is a novel antipsychotic agent approved for the treatment of cranial nerve involvement and a number of mental health conditions in several countries. In the present study, the neuroprotective effect of lurasidone by antagonist activities on histamine was investigated in a rat model of cranial nerve involvement. The antagonist activities of lurasidone on serotonin 5‑HT7, serotonin 5‑HT2A, serotonin 5‑HT1A and serotonin 5‑HT6 were analyzed, and the preclinical therapeutic effects of lurasidone were examined in a rat model of cranial nerve involvement...

INTRODUCTION: We designed a retrospective study of 59 patients with congenital sporadic non-progressive bilateral facial and abducens palsies. METHODS: Examinations included needle EMG of facial and oral muscles, facial nerve motor latency and conduction velocity (FNCV), and blink responses (BRs). RESULTS: Neurogenic EMG changes were found in one or more muscles in 55/59 patients, with no abnormal spontaneous activity. EMG changes were homogeneously neurogenic in 17 patients, homogeneously myopathic in one, and heterogeneous in 41/59 patients...

This is a case of an extensive tuberculum sella meningioma involving the circle of Willis down to the basilar artery that presented with bilateral visual loss worse on the right than left side. A one-piece right orbitopterional approach along the worse eye was used to gain access to the three cranial fossae. The orbitotomy facilitates access to the midline structures and contralateral base of the tumor with minimal brain retraction. Tumor resection is initiated by first identifying the tumor capsule, followed by piecemeal debulking via ultrasonic aspiration...

BACKGROUND: Cavernous carotid aneurysm (CCA) represents 2-9% of all intracranial aneurysms and 15% of internal carotid artery (ICA) aneurysms; additionally, giant aneurysms are those aneurysms that are > 25 mm in size. Bilateral CCAs account for 11-29% of patients and are commonly associated with structural weaknesses in the ICA wall, secondary to systemic hypertension. CCAs are considered benign lesions, given the low risk for developing major neurologic morbidities (i.e., subarachnoid hemorrhage, cerebral infarction, or carotid cavernous fistula)...

RATIONALE: Rosai -Dorfman disease (RDD) is a rare, idiopathic, and non-neoplastic histioproliferative disease with distinctive entity of unknown etiology. Central nervous system (CNS) RDD is uncommon, hence, isolated intracranial RDD is extremely rare. So far only 6 cases of CNS RDD with the lesions originating from petroclival region have been reported. We present a case of isolated intracranial RDD mimicking petroclival meningioma. PATIENT CONCERNS: A 14-year-old girl was admitted at our hospital with a 3-month history of dizziness, slowly progressing headache, and 2-month history of instability in walking...

An 86-year old man developed sequential dysfunction of trigeminal (V1), facial, abducens, trigeminal (v2), oculomotor, and hypoglossal cranial nerves on the right over 20 months. Magnetic resonance imaging (MRI) showed a lesion in the right cavernous sinus. Although there was clinical suspicion that this was related to perineural spread of an extracranial tumour, a primary lesion was not discovered. Stereotactic biopsies of the intracranial lesion were non-diagnostic, and the patient succumbed to his tumour following a period of rapid growth...
