OBJECTIVE This article reports a new variant of the persistent primitive trigeminal artery. This variant does not exist in Salas and Saltzman classifications. METHODS We analyzed CTA images of a 39-year-old male patient using RadiAnt. This work had clinical and research purposes. RESULTS A persistent primitive trigeminal artery arose from left internal carotid artery termination. Its course was atypical, superior, and lateral to the sella turcica. At its end, it joined a duplicated basilar artery. These morphological features are new compared to Salas and Saltzman's variants. CONCLUSIONS Anatomists, radiologists, and neurosurgeons must know this new variant. Angiographic analysis of this variant will keep the patient safe and perform the surgery. This new variant deserves to be considered in Salas and Saltzman classifications as a new type.
