Mao Vásquez, Luis J. Saavedra, Hector H. García, Evelyn Vela, Jorge E. Medina, Miguel Lozano, Carlos Hoyos, and William W. Lines-Aguilar

Trigeminal neuralgia (TN) is the most common type of facial pain, negatively affecting quality of life and work capacity in 34% of patients. 1 TN has a prevalence of 4–13 cases per 100,000 inhabitants 1–3 and generally affects patients older than 50 years, with a female-to-male ratio of 1.5 to 1. In primary (classic) TN, compression by vascular loops is found at the entrance of the trigeminal nerve to the brainstem. 4 , 5 In secondary TN, 6 , 7 extrinsic compression of the trigeminal nerve triggers the pain. The most common causes of extrinsic TN are

although many side effects of neurological involvements have been shown. 1 , 2 The complications included Bell’s palsy, 3 Guillain-Barre syndrome, 4 transverse myelitis, 5 and multiple sclerosis. 6 However, the incidence is not well known. Herein, we describe a case of acute trigeminal neuropathy after receiving a Pfizer-BioNtech vaccination (tozinameran) against SARS-CoV-2 in a patient who had undergone microvascular decompression (MVD) for trigeminal neuralgia (TN). Illustrative Case This case involves a 77-year-old woman with a medical history of

because of complete palsies of cranial nerves III, IV, and VI. He was also noted to have decreased sensation in the right face V1 distribution, which initially prompted an assessment for trigeminal neuralgia before neurosurgical evaluation. Magnetic resonance imaging (MRI) of the brain and orbit revealed a diffuse, homogeneously enhancing lesion at the right orbital apex involving the optic nerve sheath and dura of the right anterior hemicranium without evidence of other intracranial abnormalities ( Fig. 1 ).
