Lateral tentorial artery
Updates to Article Attributes
The lateral tentorial artery also known as lateral tentorial arcade, is a branch of the meningohypophyseal trunk (MHT) which arises from the cavernous segment of the internal carotid artery. The lateral tentorial artery runs along the lateral edge of the tentorium cerebelli.
Radiographic appearance
Due to its small size, the branches of the MHT are poorly visualised on angiography in the absence of pathologically increased blood flow, e.g. in tentorial tumours or tentorial dural arteriovenous fistula (DAVF).
When seen on frontal projections the artery shows a straight course towards the sigmoid sinus, and on lateral projections it points ain downward direction (differentiating it from the Artery of Bernasconi and Cassinari which shows an upward pointing direction).
