Facial Neuropathy Revealed: A Case Report on Trigeminal Schwannoma

Trigeminal schwannomas, rare tumors originating from Schwann cells of the trigeminal nerve, present unique diagnostic challenges due to their infrequent occurrence. The clinical manifestation of facial numbness and tingling necessitates a comprehensive approach for accurate diagnosis and optimal management. We present the case of a 45-year-old female who presented with a six-month history of progressive facial numbness localized to the left maxillary and mandibular regions. Intermittent sharp, shooting pain exacerbated by chewing and cold stimuli was reported. Physical examination revealed sensory deficits in left trigeminal nerve distribution. Magnetic resonance imaging confirmed a well-circumscribed, enhancing lesion along the left trigeminal nerve. Surgical excision of the tumor confirmed the diagnosis of schwannoma. This case underscores the significance of a detailed clinical history, advanced imaging, and collaboration between neurologists and neurosurgeons in achieving an accurate diagnosis and favorable outcome for trigeminal schwannomas. The successful surgical intervention, coupled with histopathological confirmation, contributes to the understanding of these rare tumors.
