Cranial nerve schwannomas are not uncommon intracranial tumors. Schwannomas arising from cranial nerve XI not only comprise a minority of these neoplasms but may also involve the extracranial segment of the spinal accessory nerve. The clinical presentation of cranial nerve XI schwannomas relates to their location and extent: intracranial, jugular foramen, upper neck, or cervical spine. This rep...

Cranial neuropathy is an uncommon manifestation of relapsing polychondritis (RPC). Optic neuropathy is the most common type of cranial nerve involvement in RPC. Until now, trigeminal neuralgia (TN) has been reported with different rheumatic diseases, however, there is no reported case of TN associated with RPC. We here present a case of RPC with TN. A 57 year-old female patient previously diagn...

4 Benign intracranial hypertension may occasionally be associated with cranial nerve palsies. Abducens nerve palsies occur in 10 % to 20 % patients with benign intracranial hypertension, other cranial nerve palsies occur much less frequently. We reported a 25-year-old woman benign intracranial hypertension with bilateral seventh nerve palsy. Complete improvement of her cranial nerve palsy was a...

Primary spinal cord lymphomas are rare, and either extra-/intradural masses with leptomeningeal infiltration or intramedullary in nature. These two patterns of growth do not generally overlap. The authors present a patient with a diffuse large Bcell lymphoma involving the sacral nerve root, extension to extradural space, and the cranial nerve. The literature regarding isolated nerve root lympho...

Different somatic motor neuron subpopulations show a differential vulnerability to degeneration in diseases such as amyotrophic lateral sclerosis, spinal muscular atrophy and spinobulbar muscular atrophy. Studies in mutant superoxide dismutase 1 over-expressing amyotrophic lateral sclerosis model mice indicate that initiation of disease is intrinsic to motor neurons, while progression is promot...

Pneumocephalus is a common occurrence after cranial surgery, with patients typically remaining asymptomatic from a moderate amount of intracranial air. Postsurgical pneumocephalus rarely causes focal neurological deficits; furthermore, cranial neuropathy from postsurgical pneumocephalus is exceedingly uncommon. Only 3 cases have been previously reported that describe direct cranial nerve compre...

A 77-year-old man showed bilateral abducens palsies and multiple cranial nerve enhancement on magnetic resonance images (MRI) and aseptic meningitis. He had xerophthalmia and xerostomia. Serum anti-SS-A and anti-SS-B antibodies were present. He had Sjögren's syndrome (SjS) and corticosteroid therapy ameliorated the symptoms. The cranial nerve enhancement and the cerebrospinal fluid findings wer...

introduction the abducent nucleus is located in the upper part of the rhomboid fossa beneath the fourth ventricle in the caudal portion of the pons. the abducent nerve courses from its nucleus, to innervate the lateral rectus muscle. this nerve has the longest subarachnoid course of all the cranial nerves, it is the cranial nerve most vulnerable to trauma. it has been reported that 1% to 2.7% o...

Introduction: Varicella-zoster virus may cause an infectious disease called Ramsay Hunt syndrome. The related symptoms include facial nerve palsy (FNP), otalgia, the vesicular eruptions of the auricle and external auditory canal, less common ocular movement disorder, facial hypoesthesia, myofascial pain, vestibular symptoms, hearing loss, dysphasia, vocal cord paralysis, as well as tongue paral...
