Cranial Location
Parasagittal Convexity
Parasagittal and convexity lesions sit at or near the vertex, adjacent to the superior sagittal sinus and the rolandic (motor) cortex. Meningiomas are the prototypical tumour, and the surgical priorities are motor mapping and preserving venous drainage into the sinus.
Involvement of the sinus wall dictates whether it is coagulated, partially resected or reconstructed to protect venous outflow.
