What angiographic sign which supports the diagnosis of meningioma demonstrated?
The mother-in-law sign. Contrast arrives early and stays late.
There was faint tumour blush in the region of the posterior falx post vertebral artery injection. Careful analysis showed that the arterial supply came from posterior choroidal arterial branches and deep penetrating branches of the posterior cerebral arteries. There was no arterial contribution from the middle meningeal arteries.
Given the vascular supply originated from the posterior choroidal arteries, there was no role for pre-op embolization.
