Cranial Location
Falx
The falx cerebri is the midline dural fold between the hemispheres, carrying the superior and inferior sagittal sinuses. Falcine meningiomas grow from it and may hide beneath the cortex, while parasagittal tumours involve the sinus wall itself.
The key surgical considerations are venous preservation — the bridging veins and sagittal sinus — and reaching the tumour through the interhemispheric fissure without retraction injury.
