@entity1 @entity5 @entity1163 @entity51 @entity1653 @entity1654
A case of intrasylvian @entity1653 is presented with some considerations to the clinical, radiological, and pathological features of the @entity5 . A 34-year-old Japanese @entity1 , who had experienced several episodes of @entity1163 attacks since 19 years old, was admitted to our hospital on March 22, 1983. Her plain skull roentgenogram showed abnormal calcification in her left fronto-temporal region. CT scan demonstrated clear-marginal high density mass in the left sylvian fissure which was homogeneously enhanced after administration of contrast medium. Left carotid angiogram showed intrasylvian mass with small @entity5 stain in late arterial phase, but external carotid artery had no concern with this @entity5 . On March 30, left fronto-temporal craniotomy was performed. The @entity5 was located in the extra-axial space of the sylvian fissure without any attachment to the dura mater or to the choroid plexus of the ventricles. This hard @entity5 , 70 grams in its weight, was successfully removed. It was histologically diagnosed @entity1653 . The @entity1 was discharged without any @entity51 . Twenty-four cases of @entity1653 not attached to the dura mater or to choroid plexus could be reviewed from the literature. This type of @entity1653 is occasionally called " @entity1654 ", but in some reports the @entity5 developed far from sylvian fissure. And even in the cases in which the @entity5 were reported to be located in the sylvian fissure, macroscopic space where @entity5 developed was various. The clinical features, diagnosis, and surgical management of this @entity5 were also discussed in the report.
