human infection with echinococcus granulosis is a common disease throughout south america, the mediterranean littoral, the middle east, central asia and east africa, which usually occur in children and young adults. formation of avascular cystic lesions in the liver, kidney, pancreas, bones, vitreus and brain can cause protean of signs and symptoms. intracranial cysts usually present with focal...

in this article, dynamics of the cerebrospinal fluid (csf) was studied, using computational fluid dynamics. using mri images of two special cases, a 2-dimensional model of the ventricular system was made. csf velocity and pressure distribution in ventricular system have high importance since the flow pattern of this liquid has an important effect on intracranial pressure, i.e., icp, which has a...

In this article, we present the case of a 12-year-old female child who complained of bilateral temporal and frontal headache for 2 to 3 months with nausea and vomiting. Physical examination revealed right-sided sixth cranial nerve palsy and papilledema in ophthalmoscopy. To find the cause of increased intracranial pressure, the patient underwent brain imaging and brain MRI showed no abnormality...

Ependymoma constitute 5 % to 7 % of all primary CNS neoplasm. But their prevalence relative to other tumor type varies with patient age and presenting location. Ependymoma constitute approximately 1O % of intracranial neoplasm in pediatric population and up to 30 % of those encountered in children under 3 years of age. In spinal column, ependymoma constitute 60% of glial neoplasm, and opposed...

angiofibromas are the most common benign tumors of the nasopharynx, intracranial extension has been reported in approximately 20-25% of cases. intracranial extension may be difficult to treat because of poor exposure that may lead to recurrence. a 16-year-old male patient presented with a 6-month history of nasal obstruction, intermittent epistaxis, right superior orbital fissure syndrome, and ...

introduction: oral contraceptives (ocs) are considered as one of the most common risk factor of venous thromboembolism (vte) in child bearing age. some of the recent researches indicate that the odds of vte may be even higher with newer generations of ocs. the present meta-analysis was designed to evaluate the effect of different generation of ocs on the occurrence of vte. methods: two research...

Generalised post-operative cerebral vasospasm is a major factor in delineating poor operative results following direct ruptured intracranial aneurysms. Continuous monitoring of intracranial pressure seems to be particularly helpful on such occasions, and intracranial compliance determination as well. High intracranial compliance values suggest that even small intracranial volume increases may i...

Post-lumbar puncture (LP) headache may be due to "low CSF pressure", leading to stretching of pain sensitive intracranial structures. The low intracranial pressure is secondary to net loss of intracranial CSF. It has, however, not been possible to measure intracranial CSF volume accurately during life until recently. Intracranial CSF volume can now be measured non-invasively by a MRI technique....

BACKGROUND AND PURPOSE Neurofibromatosis type I (NF1) is an autosomal dominant, hereditary, neurocutaneous syndrome purported to be associated with intracranial aneurysms. To study the relationship between NF1 and intracranial aneurysms, we have analyzed all intracranial autopsies of NF1 patients performed at our institution from 1889 to 1999 and analyzed all intracranial aneurysm cases at our ...

BACKGROUND Manual segmentations of the whole intracranial vault in high-resolution magnetic resonance images are often regarded as very time-consuming. Therefore it is common to only segment a few linearly spaced intracranial areas to estimate the whole volume. The purpose of the present study was to evaluate how the validity of intracranial volume estimates is affected by the chosen interpolat...
