Presentation
The patient was presented with long standing recurrent seizures
Patient Data
There is an extra-axial, well-defined, altered signal intensity, mass lesion arising from falx cerebri in the midline (high parietal location), returning signals are isointense on T1 WI, hyperintense on T2 WI and T2 FLAIR images with homogeneous enhancement on post-contrast images.
Marked peri-lesion vasogenic edema is noted. The mass lesion invades the adjacent superior sagittal sinus (MRV shows local occlusion of the superior sagittal sinus but reconstitutes distally via collaterals).
Case Discussion
MRI findings are of a well-defined, altered signal intensity mass lesion most likely falcine meningioma with invasion of the superior sagittal sinus as described above.
