Figures
- fig 1.
Unenhanced CT scan shows a very hypodense lesion located within a thickened layer of infolding cortex in the left hemisphere. fig 2. A, T1-weighted left parasagittal MR image shows a hyperintense mass deep in the sylvian fissure surrounded by abnormal cortex.
B, T1-weighted left axial MR image shows a hyperintense mass deep in the sylvian fissure surrounded by abnormal cortex.
C, Spin-echo T2-weighted MR image shows the hypointense mass within the infolded cortex. Note the low intensity tubular and rounded structures within the mass. Adjacent sulcus is extending deeper to the margin of the mass.
fig 3. MR angiogram, obtained by using the phase-contrast technique, shows abnormal arterial branches originating from the middle cerebral artery on the left (open arrow)
