Diagnosis of posterior circulation stroke may be challenged. National Institutes Health Stroke Scale (NIHSS) and brain imaging (non-contrast computed tomography-CT) are used for diagnosis; evaluation on remains a limit NIHSS, the value non-contrast CT (NCCT) is limited due to artifacts caused by bones base skull. We tested validity prognostic Alberta Program Early Score (pc-ASPECTS) in patients...
BACKGROUND Gangliogliomas are low-grade glioneuronal tumors of the central nervous system and the commonest cause of chronic intractable epilepsy. Most gangliogliomas (>70%) arise in the temporal lobe, and infratentorial tumors account for less than 10%. Posterior fossa gangliogliomas can have the features of a classic supratentorial tumor or a pilocytic astrocytoma with focal gangliocytic diff...
BACKGROUND The number and volume of abnormalities on baseline brain magnetic resonance images in patients with initial findings suggestive of multiple sclerosis are known to predict outcome in terms of disability. However, no long-term data exist on specific locations or types of lesions. OBJECTIVE To assess the long-term predictive value of baseline magnetic resonance imaging parameters, inc...
BACKGROUND The most common type of vascularized tumor located in the posterior incisural space in older patients is the falcotentorial meningioma. Solid hemangioblastomas are rarely found in this particular area of the brain. To the best of our knowledge, the case of only one patient harboring a hemangioblastoma not associated with Von Hippel-Lindau disease has been previously reported in the l...
We compared MRI criteria used to predict conversion of suspected multiple sclerosis to clinically definite multiple sclerosis. Seventy-four patients with clinically isolated neurological symptoms suggestive of multiple sclerosis were studied with MRI. Logistic regression analysis was used to remove redundant information, and a diagnostic model was built after each MRI parameter was dichotomized...
We present a rare case of infratentorial mastoid trepanation, by drilling, from medieval Croatia. An artificial ante-mortal opening was found in a male skeleton from the 11th century cemetery Zvonimirovo. It was placed roughly at the intersection of the Frankfurt's plane and the midline of the right mastoid. The right posterior parietal of the deceased also exhibited a callus-like formation con...
OBJECTIVE To clarify associations between intracerebral hemorrhage (ICH) location and clinical outcomes among participants of the main phase Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT2). METHODS Associations between ICH sites and poor outcomes (death [6] or major disability [3-5] of modified Rankin Scale) and European Quality of Life Scale (EQ-5D) utility ...
BACKGROUND Friedreich ataxia (FRDA) is the commonest form of autosomal recessive ataxia. This study aimed to define the extent of the brain damage in FRDA patients and to identify in vivo markers of neurodegeneration, using diffusion-weighted imaging (DWI). METHODS We studied 27 FRDA patients and 21 healthy volunteers using a 1.5 T scanner. Axial DW images were obtained and mean diffusivity (...
OBJECTIVE Low serum total cholesterol levels are associated with an increased risk of symptomatic intracerebral hemorrhage and with presence of asymptomatic cerebral microbleeds. The relative contribution of lipid fractions to these associations is unclear and requires investigation. We determined whether serum HDL-cholesterol, LDL-cholesterol, and triglycerides are associated with risk of intr...
