High grade and metastatic brain tumours exhibit considerable spatial variations in proliferation, angiogenesis, invasion, necrosis and oedema. Vascular heterogeneity arising from vascular co-option in regions of invasive growth (in which the blood-brain barrier remains intact) and neoangiogenesis is a major challenge faced in the assessment of brain tumours by conventional MRI. A multiparametri...

INTRODUCTION High grade gliomas are the most common primary malignant brain tumours. Treatment with chemoradiation and adjuvant chemotherapy with Temozolomide may prolong survival but some patients develop complications during or soon after therapy due to radiation necrosis, oedema or tumour progression. PATIENTS We report the use of Bevacizumab in four patients with newly diagnosed high grad...

We present a female patient in her late 30s, with baseline vegetative state following prior traumatic brain injury, who presented with prolonged right hemispheric status epilepticus. The neuroimaging revealed a striking right-sided pancortical oedema with left (crossed) cerebellar diaschisis and dilation of right hemispheric arteries. EEG was concordant and showed nearly continuous right hemisp...

Stroke is a leading cause of death, disability and dementia worldwide. Despite extensive pre-clinical investigation, few therapeutic treatment options are available to patients, meaning that death, severe disability and the requirement for long-term rehabilitation are common outcomes. Cell loss and tissue injury following stroke occurs through a number of diverse secondary injury pathways, whos...

The present study is aimed at finding radiological parameters which could provide indirect information on invasive growth of meningioma, relevant enough to predict the possible risk of postoperative neurological deficit development. The cohort was composed of 40 consecutive adult patients of comparable general condition parameters (age 18-75 years, KRS 70-100, ASA 1-2) with meningiomas attackin...

Cerebral oedema can be classified as the tangible swelling produced by expansion of the interstitial fluid volume. Hydrocephalus can be succinctly described as the abnormal accumulation of cerebrospinal fluid (CSF) within the brain which ultimately leads to oedema within specific sites of parenchymal tissue. Using hydrocephalus as a test bed, one is able to account for the necessary mechanisms ...

Laser ablation for treatment of hypothalamic hamartoma (HH) is a minimally invasive and effective technique used to destroy hamartomatous tissue disconnect it from the functioning brain. Currently, gold standard evaluate amount being “burned” use heat maps during procedure. However, these have low spatial resolution can be misleading in terms extension damage. The aim this study different MRI s...

Stroke is the second leading cause of death worldwide, affecting about 240 people a day in South Africa and leaving survivors with residual disabilities. At the moment, there is no clinically approved neuroprotective product for stroke but the consumption of plant polyphenols has been suggested to offer some protection against stroke. In this study, we investigated the effects of long-term cons...

Objective. Encephalopathy and brain edema are serious complications of acute liver injury and may lead to rapid death of patients. The present study was designed to investigate the role of the inflammatory mediators and oxidative stress in the cytotoxic brain oedema and the neuroprotective effects of both minocycline and dexamethasone. Methods. 48 male albino rats were divided into 4 groups: co...

Abstract Introduction: The aim of this study was to investigate the antinociceptive and antiinflammatory effects of Teucrium hyrcanicum aqueous extract in male mice and rats. Methods: To assess the antiinflammatory effect, we used carrageenan- and dextran-induced paw oedema and for determination of the antinociceptive effect, acetic acid-induced writhing, tail flick and formalin pain tests ...
