The aim of this study was to compare the frequency of pathological types of smooth-pursuit and saccadic movements in different localizations of vestibular lesions. We tested 112 patients using videonystagmography. The smooth pursuit was appreciated qualitatively on the basis of Malecki's patterns. We analyzed the saccadic movements taking three parameters into consideration: latency, velocity, ...

Painful tic convulsif is a syndrome restricted to paroxysmal dysfunction of the fifth and seventh cranial nerves. It occurs primarily in women over the age of 50 years and is usually associated with an ectatic vertebrobasilar artery--less frequently an arteriovenous malformation or cholesteatoma--which compresses the trigeminal and facial nerve roots in the posterior fossa. In rare instances th...

Received 10 February 2014 Accepted 26 July 2014 Online 31 July 2014 Print 31 July 2014 Tumors of the posterior fossa of brain leads to complications like brain stem compression, herniation and death because of its critical location, limited space and involvement of vital brain stem nuclei. This study has been conducted in the department of Pathology and Neurosurgery, Gandhi Medical College, Sec...

Primary intracranial melanoma is an extremely rare lesion of the brain. A 28 years old lady, without any co-morbid conditions, presented with headache and left side facial numbness. MRI of brain showed a mass lesion in left middle cranial fossa extending into posterior fossa, with signals characteristics of melanoma. Histology and immunohistochemistry confirmed the diagnosis after surgical exci...

Variations of the posterior cranial fossa can alter surgical approaches to this region and pose a definite hazard if not considered. Inadvertent tearing of these large structures can result in morbidity and even mortality. We report an unusually large occipital sinus (1.5 cm x 6 cm) that instead of draining into the marginal sinus inferiorly, drained laterally into the jugular foramen and thus ...

The purpose of this study was to relate the facial asymmetries with possible impairments of the skull base, particularly with regard to the three-dimensional position of the glenoid fossa. Fifty-eight subjects met the inclusion criteria (25 men and 33 women) and were included in the analysis. All patients underwent three-dimensional computed tomographies. Patients were classified into 3 asymmet...

BACKGROUND True lambdoid synostosis (TLS) produces a consistent morphology that includes occipital flattening, an ipsilateral occipitomastoid prominence, and a mild contralateral hemifacial deficiency that minimally improves with surgery. Prior studies have demonstrated that dysmorphic middle and posterior cranial fossae contribute to the craniofacial scoliosis characteristic of TLS. We hypothe...

Dr. Felipe Slaviero – Edifício das Clínicas Rua Teixeira Soares, 885 / 10o andar 99010-901 Passo Fundo RS Brasil. E-mail: [email protected]. Intracranial arachnoid cysts are congenital collections of fluid that develop within the arachnoid membrane because of splitting or duplication of this structure. It corresponds to 1% of all non-traumatic intracranial mass lesions. Arachnoid cysts...

The aims of this study were to investigate the relationships between the cranial base, including the glenoid fossa and maxillofacial morphology, obtained by three-dimensional (3D) computed tomography (CT). The specimens were 45 Skeletal I and Skeletal II dry skulls of modern Japanese males without marked crowding, anterior crossbite, or maxillofacial asymmetry, which had been preserved in the T...

These are a group of congenital malformations that involve the cranial cavity and the central nervous system.The Dandy-Walker variant is the commonest posterior fossa malformation, while craniosynostosis is the premature fusion of one or more of the cranial sutures causing abnormal shape of the head. They present with hydrocephalus and features of increased intracranial pressure, thus, the goal...
