“…[3] However, since extra-axial mass effects from contralateral lesions make the detection of the site of trigeminal nerve compression challenging, even with high-resolution MRI, there have been no reports objectively indicating the site of TN. [4,5,12,13,15,16] In the present case, right supraorbital nerve stimulation evoked a delayed ipsilateral R1 latency despite normal R2 responses to ipsilateral stimulation and R1 responses to contralateral stimulation. ese findings indicate damage to the main sensory nucleus of the trigeminal nerve in the right pons.…”

“…However, TN has also been reported in some patients with contralateral VSs. [ 4 , 5 , 13 , 14 , 16 , 17 ] Since a massive mass effect from contralateral lesions could limit the accuracy of preoperative evaluation of trigeminal nerve compression, the causal relationship between TN and contralateral VS remains unclear. [ 4 , 5 , 13 , 14 , 16 , 17 ] Blink reflex (BR) testing is a noninvasive electrophysiological method used to evaluate the localization and degree of TN.…”

Background: Although the blink reflex (BR) is effective in objectively evaluating trigeminal neuropathy, few studies have demonstrated its effect on trigeminal neuralgia (TN). The authors report a patient with TN due to contralateral vestibular schwannoma (VS) functionally diagnosed by delayed R1 latency of the BR. Case Description: A 36-year-old man presented with left-sided deafness and paroxysmal facial pain in the right V1-3 area. Magnetic resonance imaging (MRI) showed a solid cystic mass compressing the right pons and left brainstem at the left cerebellopontine angle. Although preoperative BR evoked by right supraorbital nerve stimulation-induced delayed ipsilateral R1 latency and normal ipsilateral and contralateral R2 responses, the BR latency evoked by left supraorbital nerve stimulation was normal, indicating deficits in the principal nucleus of the trigeminal nerve in the right pons. The symptoms of TN disappeared after the removal of the VS. Postoperative MRI showed subtotal removal of the tumor and sufficient decompression of the pons and cerebellopontine cistern. The R1 latency returned to normal 50 days after surgery. Conclusion: The perioperative BR test was not only useful for objective evaluation of the localization of trigeminal neuropathy but also correlated with the symptoms of TN.

“…To date, there are very few case reports [1,7] in the literature of acoustic neuroma mimicking facial paresthesia, whereas most of the published work [8][9][10][11] is on trigeminal neuralgia or oromandibular pain secondary to acoustic neuroma. When the tumor reaches a size of 2 cm, it extends out of the acoustic meatus and starts to compress the trigeminal nerve [12].…”

Acoustic neuromas are benign neoplasms of the brain composed of Schwann cells, arising most commonly from the nerve sheath of the vestibular division of the VIII cranial nerve. They usually manifest as unilateral hearing loss, tinnitus, and unsteadiness. Some patients may present atypically with symptoms like orofacial pain, hemifacial numbness, sudden onset hearing loss, or trigeminal neuralgia. Here we report an interesting case of acoustic neuroma in which the patient presented with unilateral facial numbness and tooth pain. Persistent atypical symptoms should always raise clinical suspicion of this pathology, necessitating the need for higher radiological investigations (CT or MRI) to aid in the early diagnosis and treatment.

Vestibular schwannoma with contralateral facial pain – case report

Abstract: Background: Vestibular schwannoma (acoustic neuroma) most commonly presents with ipsilateral disturbances of acoustic, vestibular, trigeminal and facial nerves. Presentation of vestibular schwannoma with contralateral facial pain is quite uncommon.
