[CT analysis on correlation of parasagittal sinus and parafalx meningiomas with sagittal sinus and falx].
The computed tomographic characteristics of 59 cases of parasagittal sinus and parafalx meningiomas which were verified in operation and pathology are analysed. They were found as follows: (1) the striding sign of the tumor for the superior sagittal sinus and/or falx; (2) the smooth sign of the interior edge of the tumor; (3) the turning sign of the falx for one side of the tumor; and (4) the thickness and density increasing sign of the falx and/or sagittal. Based on the operation findings, the pathologic bases and clinical values are also discussed.
