Cerebral venous thrombosis (CVT) is a clinical condition which is caused by the partial or complete occlusion of the dural sinuses and cerebral veins. Cases of associated CVT and multiple sclerosis (MS) have been reported and CVT development has been attributed to the previous lumbar puncture (LP) in majority of these cases. We report a case of 32-year-old woman with no previous history of rece...

A 10-year-old girl with features of Klippel Trenaunay Syndrome developed a large left frontoparietal subdural hemorrhage. CT angiography and cerebral angiography identified prominent subependymal veins and deep venous system predominantly in the left cerebral hemisphere in association with a dilated left vein of Labbe and hypoplastic superior sagittal sinus. No arteriovenous malformation or fis...

Intracranial hypotension increases cerebral blood flow. In dogs the average increase in cortical blood flow was 30 ml./100 g/min (47%) when the intracranial pressure was lowered acutely from 100 to 40 mm CSF. Permanent intracranial hypotension was established in seven demented patients using a ventriculoatrial shunt. The mean post shunt pressure was 50 mm CSF. In this group, the cerebral vascul...

Cerebral sinovenous thrombosis (CSVT) is rare and occurs in three to four persons per one million of population per year1. Deep cerebral venous system involvement is present only in 10% of CSVT2. Thrombosis of deep cerebral veins presents with headache, encephalopathy, and variable focal deficits, and is associated with increased risk of death or dependence if not recognized and treated promptl...

The treatment of dural arteriovenous fistulas (DAVFs) at the foramen magnum remains controversial by reason that DAVFs appearing from the foramen magnum represent only a minority of spinal DAVFs. We present our treatment for an asymptomatic patient suffering from a foramen magnum DAVF. A 53-year-old man presented to our hospital with the complaint of a floating sensation. Although there was no ...

Low-intensity signal seen within areas of narrowing within the ventricular system has been termed the CSF flow-void sign. This decreased signal is related to CSF flow and turbulence. Seven normal volunteers were examined, and the changes that occurred in the appearance of the CFVS were noted when data acquisition was modified by cardiac gating. Flow-void patterns within the internal cerebral ve...

BACKGROUND AND PURPOSE The purpose of this study was to determine the incidence of adult cerebral venous thrombosis. METHODS A retrospective cross-sectional study was conducted among all 19 hospitals located in 2 Dutch provinces serving 3.1 million people. Adult cerebral venous thrombosis cases diagnosed between January 1, 2008, and December 31, 2010, were identified using the Dutch financial...

Neuropathological findings in children who had died of cerebral arteriovenous malformation under 6 years of age were contrasted with those of children aged 6 to 15 years. In all subjects, the abnormalities were more marked in the shunting vessels and veins distal to the arteriovenous shunt than in the arteries. Fibrous thickening, calcification an adherent thrombus of vessel wall, and gliosis a...
