Twisted vessels: Arteriovenous malformations are twisted arteries and veins which can grow and have aneurysms associated with them. They have brain tissue in the middle of the twisted vessels. The danger is hemorrhage. They cause weak walled veins to become engorged and enlarged under arterial flow as the two of them become connected. Interventional neurosurgeons treat these well.

Knot of blood vessel: Cerebral avms are a knot of blood vessels in which there is a direct connection between the arteries and veins. They are often congenital but can develop after head trauma. They are often discovered during the work-up for a seizure and are a risk for brain bleeds. Depending on the size and location, they can be treated surgically, endovascularly or with radiation - or a combination of those.
