Background: Intracranial hypertension (IH) is a secondary clinical condition due to the loss of brain compensatory mechanisms, leading increased intracranial pressure (ICP) and changes in cerebral blood flow, which can result hypoxia, injury, herniation. Brain4care (b4c) device that explores variations compliance allows measurement ICP non-invasive serial way, addition, it predict evolution tre...

neurofibromatosis type 2 is an inherited disease. the main manifestation of the disease is the development of symmetric, non-malignant brain tumors in the region of the cranial nerve viii usually as schwannoma. we report here a 20-year-old woman with primary intracranial malignant nerve sheath tumor located in the left cerebellopontine angle. histologically, the tumor showed malignant spindle c...

conclusions primary extracranial meningiomas (pems) without intracranial origin are very rare and because of their slow growing nature are initially managed by primary care physicians. case presentation we report a case of slowly progressing extracranial meningioma that was presented in a young adult woman. the tumor was asymptomatic but large enough to cause cosmetic discomfort. patient underw...

introduction: schawannomas (neuromas, neurilemmomas) are benign tumors originating from showann cells or nerve fiber sheet cells. they are solitary, encapsulated tumors usually attached to, or surrounded by a nerve. case report: we present a case of left hypoglossal nerve schwannoma in a 19 year old man who was admitted with progressive left tongue atrophy. conclusion: schwannoma of the hypoglo...

Serial electrocardiographic (E.C.G.) recordings were taken in seven patients suffering from intracranial conditions, for which their intracranial pressure was directly and continuously monitored with a Konigsberg extradural transducer. The E.C.G. changes observed in patients with raised intracranial pressure were prominent U waves, ST-T segment changes, notched T waves, and shortening and prolo...

Intracranial hypertension (ICH) was systematized in four categories according to its aetiology and pathogenic mechanisms: parenchymatous ICH with an intrinsic cerebral cause; vascular ICH, which has its actiology in disorders of cerebral blood circulation: ICH caused by disorders of cerebro-spinal fluid dynamics and idiopathic ICH. The increase of intracranial pressure is the first to happen an...

OBJECTIVE To assess the impact of intracranial pressure monitoring on the short-term outcomes of traumatic brain injury patients. METHODS Retrospective observational study including 299 consecutive patients admitted due to traumatic brain injury from January 2011 through July 2012 at a Level 1 trauma center in São Paulo, Brazil. Patients were categorized in two groups according to the measure...

BACKGROUND AND PURPOSE The intracranial volume is commonly used for correcting regional brain volume measurements for variations in head size. Accurate intracranial volume measurements are important because errors will be propagated to the corrected regional brain volume measurements, possibly leading to biased data or decreased power. Our aims were to describe a fully automatic SPM-based metho...

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...
