Deep Sylvian fissure meningiomas: A case report

Figure 1 Computed tomographic angiography before the first operation. A: A preoperative non-contrast enhanced axial computed tomographic (CT) shows an area of high density in the right Sylvian fissure, most likely a calcification (an 11 mm × 12 mm × 12 mm mass lesion); B: Contrast CT imaging shows an enhanced mass in the right deep Sylvian fissure region with edema and areas of calcification; C: Computed tomographic angiography did not show any tumor stain or dilatation of the middle cerebral artery.
