BACKGROUND: Vertebrobasilar dolichoectasia (VBD) is a clinical entity associated with ischemic stroke, compression of cranial nerves or brainstem, and hydrocephalus. There have been relatively few studies following the progression of VBD in patients presenting with a variety of diverse clinical features. CASE PRESENTATION: Here, we report a case study of a male with progressive VBD who was followed from November 2012 to December 2016. The patient had diagnosed hypertension for several years and suffered from left peripheral facial paralysis, recurrent ischemic attacks in the brainstem and cerebellum, obstructive hydrocephalus and frequent pneumonia...

BACKGROUND: Carotid artery restenosis may occur following ipsilateral carotid endarterectomy (CEA). It remains unclear whether carotid artery stenting (CAS) or a repeat CEA (redoCEA) is the best treatment strategy for carotid artery restenosis. OBJECTIVE: We sought to find whether CAS or redoCEA is the optimal therapy for post-endarterectomy carotid restenosis. METHODS: This study was performed according to the PRISMA and MOOSE guidelines...

We describe the case of a 73-yr-old female patient with a 2-yr history of diplopia that has progressively become worse. Physical examination revealed a right VI cranial nerve (CN) palsy. Magnetic resonance imaging and angiography showed a dolichoectatic basilar artery near the VI CN. A suboccipital craniectomy was performed, initially with the intention to perform a microvascular decompression; however, a red mass was encountered at the entrance of the right Dorello's canal that was compressing the VI CN. Complete resection of the lesion was done and decompression of the nerve was accomplished...

Meckel's cave is a dural recess in the posteromedial portion of the middle cranial fossa that acts as a conduit for the trigeminal nerve between the prepontine cistern and the cavernous sinus, and houses the Gasserian ganglion and proximal rootlets of the trigeminal nerve. It serves as a major pathway in perineural spread of pathologies such as head and neck neoplasms, automatically upstaging tumours, and is a key structure to assess in cases of trigeminal neuralgia. The purpose of this pictorial review is threefold: (1) to review the normal anatomy of Meckel's cave; (2) to describe imaging findings that identify disease involving Meckel's cave; (3) to present case examples of trigeminal and non-trigeminal processes affecting Meckel's cave...

Background: Brucellosis is an important multisystemic disease with many different clinical symptoms, and its early diagnosis and treatment are possible. Neurobrucellosis (NB) is a rare but serious finding of brucellosis. Brucella can be seen as meningitis and encephalopathy, and it can cause cranial nerve pathologies, vascular syndromes, myopathy, spinal diseases, and psychiatric disorders. In NB, vascular syndromes secondary to inflammation are rarely seen. Here, we present nine young patients with vascular and nonspecific neuropsychiatric findings who had NB as the etiology of stroke...

A 9-year-old girl presented with lower motor neuron type of paralysis involving limbs, trunk and multiple cranial nerves (7, 9 and 10) with preceding history of mumps 1 week before the onset of weakness. There were no features to suggest either a meningitis or encephalitis in the child. Cerebrospinal fluid showed hypoglycorrhachia and mild protein elevation; magnetic resonance imaging of the brain was normal. Nerve conduction study showed motor axonal neuropathy. Serology for mumps IgM was positive, consistent with a diagnosis of post-mumps acute motor axonal polyneuropathy...

Herpes zoster, caused by reactivation of varicella-zoster virus, is uncommon in infancy. Even more uncommon is herpes zoster ophthalmicus, defined as herpes zoster of the ophthalmic branch of the fifth cranial nerve. Among healthy children, primary varicella-zoster virus infection during gestation as a result of maternal varicella or the first year of life is the major risk factor for development of herpes zoster in a relatively young age. Here we present an unusual case of herpes zoster ophthalmicus with dissemination in an immunocompetent toddler with favorable outcome...

Tick paralysis is caused by neurotoxins secreted by adult female ticks, primarily in North America and on the east coast of Australia. Sporadic illness is also recorded in Europe and Africa. In the European countries, including Poland, there are 6 species of ticks capable of causing tick paralysis. The disease occurs in people of all ages, but is most commonly diagnosed in children under 8 years of age. Paralysis can take different forms - from rare isolated cranial nerve infections to quadriplegia and respiratory muscles paralysis...

Background: Compared with full-term infants, very preterm infants are more vulnerable to injury and long-term disability and are at high risk of death. The predictive value of ultrasound and imaging on the neurodevelopment is one of the hot topics. This study aimed to investigate the relationship between cranial ultrasound (cUS) variables and neurodevelopmental outcomes of very preterm infants. Methods: Totally 129 very preterm infants (gestational age ≤28 weeks) in neonatal intensive care unit of Hunan Children's Hospital between January 2012 and November 2014 were included in this retrospective study...

The classic columnar model of cranial nerve central representation assumes that all motor and sensory hindbrain neurons develop within four radial migration domains, held to be separated by a sulcal alar-basal boundary (sulcus limitans). This essay reviews a number of developmental data that challenge these concepts. These results are interpreted within the framework of present day neuromeric conception of the brainstem (the prosomeric model). Advances in dorsoventral patterning of the spinal cord and hindbrain now show that there exist up to eight alar microzones and five basal microzones (molecularly and histogenetically distinct longitudinal progenitor domains)...

Originally discovered in elasmobranchs by Fritsh in 1878, the nervus terminalis has been found in virtually all species, including humans. After more than one-century debate on its nomenclature, it is nowadays recognized as cranial pair zero. The nerve mostly originates in the olfactory placode, although neural crest contribution has been also proposed. Developmentally, the nervus terminalis is clearly observed in human embryos; subsequently, during the fetal period loses some of its ganglion cells, and it is less recognizable in adults...

Neuropathies can occur in patients with diffuse large B-cell lymphoma (DLBCL) at any stage of the disease as a presenting symptom or during later stages of illness. A wide spectrum of neurological association is known to occur with DLBCL, ranging from cranial nerve palsies to peripheral neuropathies. Evaluation of cranial and peripheral neuropathies in patients with DLBCL requires meticulous clinical, imaging, and electrodiagnostic testing. A 75-year-old right-handed female with a known history of multiple cranial neuropathies and DLBCL presented with acute dysphagia and upper extremity weakness of one-week duration...

CHARGE syndrome is linked to autosomal dominant mutations in the CHD7 gene and results in a number of physiological and structural abnormalities, including heart defects, hearing and vision loss and gastrointestinal (GI) problems. Of these challenges, GI problems have a profound impact throughout an individual's life, resulting in increased morbidity and mortality. A homologue of CHD7 has been identified in the zebrafish, the loss of which recapitulates many of the features of the human disease. Using a morpholino chd7 knockdown model complemented by a chd7 null mutant zebrafish line, we examined GI structure, innervation, and motility in larval zebrafish...

The hypoglossal or twelfth cranial nerve is the motor nerve to the extrinsic and intrinsic muscles of the tongue, and the superior root of the ansa cervicalis and the thyrohyoid and geniohyoid branches are delivered through the nerve. This study investigated the muscular branches of the hypoglossal nerve to clarify their spatial relationships with the muscles of the tongue and the neighboring structures. The muscles and the nerve were gross anatomically examined in 42 cadavers. The superior root and the thyrohyoid branch left the nerve near the occipital and lingual arteries, respectively...
