Part of the Cohen Collection. Neurovascular compression is a major cause of TN, which is defined as an "abnormal" contact between an artery We describe the MRA and MR angiography (MRA) features of persistent trigeminal artery (PTA) found incidentally in eight patients, with special attention to its origin, site and course. A cerebellar artery that arises from the precavernous segment of the internal carotid artery (ICA) without connecting to the basilar artery is regarded as a PTA variant. However, for patients who have contraindications to MRI, CT cisternography is shown to also be an effective method f … Jan 1, 2015 · Neurovascular compression (NVC) of the trigeminal nerve is the primary cause of trigeminal neuralgia (TN) but is known to occur in both symptomatic and asymptomatic nerves. Sep 6, 2025 · MRI with specialized sequences can identify vascular compression of the trigeminal nerve, which is a common cause of trigeminal neuralgia 1 Congruence rates between MRI findings and intraoperative findings for neurovascular contact range from 83% to 100% 2 The superior cerebellar artery is the most common vessel causing compression 1 We would like to show you a description here but the site won’t allow us. It resembles the Greek letter τ, pronounced "tau", and is equivalent to the modern-day "T&q Correlating with intermittent and excruciating pain of right otalgia, the presence of vascular compression of right superior cerebellar artery onto superior surface of right trigeminal nerve at nerve root entry zone raises high suspicion of right Trigeminal neuralgia is most commonly caused by vascular compression at the trigeminal nerve (TN) root entry zone. Trigeminal neuralgia (cranial nerve V) has 4 days ago · A patient presenting with right eye ptosis combined with trigeminal nerve ophthalmic (V1) and maxillary (V2) division involvement requires immediate neuroimaging—specifically MRI with gadolinium and MRA or CTA—to urgently exclude compressive lesions such as cavernous sinus pathology, posterior communicating artery aneurysm, or tumors that A proximal hypoplastic basilar trunk below the anastomosis that enlarges to a more normal caliber above the aberrant communication is an important ancillary sign of persistent trigeminal artery and should be searched for on routine MR studies in cases with suspected carotid-basilar anastomoses. Feb 22, 2016 · The purpose of this article is to review the trigeminal nerve's anatomy relevant to TN and to describe the imaging appearance of vascular compression of the trigeminal nerve in patients with TN. Microvascular decompression (MVD) has been established as a useful treatment. Jul 31, 2025 · The MRI also identifies if a blood vessel is pressing on the trigeminal nerve, a common cause of classic trigeminal neuralgia.
