Abstract

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).

Özet

Persistan primitif trigeminal arter (PPTA), anormal embriyonik vasküler yapı olup karotis arter ve vertebrobasiler sistem arasında bulunur. PPTA sıklıkla internal karotid arterin kavernöz segmentinden kaynaklanmakta olup basiller arterin santral kesimiyle birleşir. Hipofiz adenomları gibi sellar lezyonlara eşlik eden PPTA nadiren görülür ve PPTA, trigeminal nevraljinin nadir bir nedeni olabilir. Biz burada prolaktin salgılayan hipofiz adenomuna eşlik eden PPTA ve trigeminal nevraljiye neden olan PPTA tanısını manyetik rezonans görüntüleme (MRG) ile koyduğumuz iki olgu sunuyoruz. Cerrahi tedavinin planlanmasında ve yol göstermesinde invaziv yöntem olan serebral dijital substraksiyon anjiyografi (DSA)’den kaçarak, yerine MRG’nin kullanılabileceğini düşünüyoruz.
