The artery of Bernasconi and Cassinari, also known as medial or marginal tentorial artery (of Bernasconi–Cassinari), commonly arises from the cavernous segment of the internal carotid artery.
Due to its small size, the artery of Bernasconi and Cassinari is poorly visualized on angiography in the absence of pathologically increased blood flow. When seen, it has a wavy appearance on angiography.
History and etymology
It was first described by Bernasconi and Cassinari in the setting of tentorial meningiomas.
Lesions arising from the tentorium cerebelli, such as tentorial dural arteriovenous fistulas may derive arterial blood supply from the artery of Bernasconi and Cassinari.
The artery of Bernasconi and Cassinari is also the most likely artery to be enlarged on an angiogram in tentorial meningiomas.
Occasionally, it may provide essential collateral blood flow to the posterior circulation.
