Multiple cerebral aneurysms with persistent primitive trigeminal artery.
We report a patient with a persistent primitive trigeminal artery (PPTA) detected incidentally during cerebral angiography for the ruptured aneurysm. Cerebral angiography revealed a PPTA and eight anterior circulation cerebral aneurysms. Although cerebrovascular fragility, hemodynamic stress and hypertension are well known as etiologic factors for development of cerebral aneurysms, there is a known association of aneurysms with a PPTA, fetal carotid-basilar anastomosis. Furthermore, this case is rare from the viewpoint of aneurysm multiplicity.
