An Atypical Presentation of Acoustic Neuroma With Facial Paresthesia: A Case Report

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.
