Mother in law sign – used to describe lesions that enhance early during the arterial phase and remain opacified well after the venous phase. The sign is joking named after the uncanny ability of mothers in law to come early and stay late. This matches the classic angiographic enhancement pattern of meningiomas. The above lateral angiogram images from a common carotid artery injection demonstrate a large olfactory groove meningioma.
