[ XXXX of cortical vein: a case report].

A 39-year-old @entity1 presented with disturbed @entity1662 , left @entity1269 and @entity10 . CT scan revealed @entity548 in the right parietal region, which had lower density than usual intracerebral @entity548 and was associated with irregular perifocal @entity4 . Cerebral angiograms revealed narrowed cortical vein with irregular wall in the right parietal region, where delayed local blood flow into the deep cerebral veins through collateral vessels was noted. The diagnosis was @entity548 due to @entity715 of cortical vein. Her symptoms and @entity2657 were progressive. To reduce intracranial pressure, evacuation of the @entity1410 was performed. The @entity1410 which existed 1cm under the right parietal cortex was about 20g in weight. She remarkably improved soon after operation. Frequency of sinovenous @entity715 has been reported to be about 10% of all cerebral @entity63 , however, localized @entity49 is rare among them. This is because it is not always symptomatic and it is difficult to make accurate diagnosis. Six cases of localized @entity49 were reviewed, in which accurate diagnosis were established by cerebral angiograms, CT scan and/or autopsy. Clinical and radiological features of this case were presented.
