Persistent primitive trigeminal artery as a cause of trigeminal neuralgia and persistent primitive trigeminal artery associated with pituitary adenoma: Two case reports
Persistent primitive trigeminal artery (PPTA) is an abnormal
embryonic vascular structure that provides connection between
the carotid artery and vertebrobasilar system. PPTA usually
originates from cavernous segment of internal carotid artery (ICA)
and contacts with the central part of the basilar artery. The sellar
lesions such as pituitary adenoma accompanying PPTA are very
rare and PPTA is an unusual cause of trigeminal neuralgia. Herein,
we present two cases of PPTA along with a prolactin secreting
pituitary adenoma and trigeminal neuralgia (TN) due to PPTA,
diagnosed by magnetic resonance imaging (MRI). We suggest that
MRI would be able to properly plan and execute surgical treatment
and avoid cerebral digital subtraction angiography (DSA).
