Background: An epidermoid cyst is a rare tumor of the cerebellopontine angle region. It usually presents with ipsilateral compressive symptoms. The contralateral trigeminal neuralgia is an unusual presentation in such cases. We did not find such case reports in the literature.
Case Description: Here, we report a case of a 62-year-old female with a right cerebellopontine angle epidermoid cyst presenting with right hearing impairment and the contralateral trigeminal neuralgia.
Conclusion: The possible mechanism leading to the contralateral trigeminal neuralgia is discussed here along with the diagnosis and management of the case.

Purpose: Electrical stimulation of trigeminal nerve branches elicits early and late reflex responses in the cervical muscles, known as the trigeminocervical reflex (TCR). This study aimed to evaluate the neurophysiological aspects, stimulation patterns, and topographic distribution of short-latency TCR components in humans in the absence of voluntary muscle activation.
Methods: This prospective observational study included 30 participants.

Purpose And Background: The trigeminal artery is a rare anatomical variant, representing an embryonic vestige of the anastomosis between the internal carotid artery and the posterior circulator system, that can be asymptomatic or could have vast clinical manifestations produced by insufficient flow or by vascular nervous conflicts. This study is an anatomical presentation of 3 trigeminal artery cases observed at Medimar Imagistic Services Constanta.
Methods: The 3 trigeminal artery cases were discovered on a 860 magnetic resonance angiographies (0.

Background: There is growing evidence that botulinum neurotoxin (BoNT) can mediate changes at the central level through peripheral mechanisms, leading to alterations in central sensorimotor integration. However, the effect of BoNT on brainstem excitability in patients with hemifacial spasm(HFS) is not yet fully understood, and its long-term effects remain unknown.
Objective: This study aims to investigate the impact of BoNT on the excitability of the facial nucleus in patients with idiopathic HFS.

The most frequent of the embryonic persistent arteries that connect the internal carotid artery to the posterior circulation is the persistent primitive trigeminal artery (PPTA), which is recognized on 0.1%-0.6% on the basis of conventional angiography or magnetic resonance imaging (MRI).
