Clinical narrative: cranial nerve inflammation/palsy; brain inflammation; hearing loss in my right ear; severe headache behind my right eye; loud high pitched ringing in both ears; double-vision; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP). The reporter is the patient.  A 56 year-old male patient received bnt162b2 (BNT162B2), administered in arm left, administration date 06Mar2021 (Lot number: EN6200) at the age of 55 years as dose 1, single for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. The following information was reported: CRANIAL NERVE PALSIES MULTIPLE (disability, medically significant) with onset 06Mar2021, outcome "recovering", described as "cranial nerve inflammation/palsy"; NONINFECTIVE ENCEPHALITIS (disability, medically significant) with onset 06Mar2021, outcome "recovering", described as "brain inflammation"; DEAFNESS (disability, medically significant) with onset 06Mar2021, outcome "not recovered", described as "hearing loss in my right ear"; HEADACHE (disability) with onset 06Mar2021, outcome "not recovered", described as "severe headache behind my right eye"; TINNITUS (disability) with onset 06Mar2021, outcome "not recovered", described as "loud high pitched ringing in both ears"; DIPLOPIA (disability) with onset Mar2021, outcome "recovered" (Apr2021), described as "double-vision". The events "cranial nerve inflammation/palsy", "brain inflammation", "hearing loss in my right ear", "severe headache behind my right eye", "loud high pitched ringing in both ears" and "double-vision" were evaluated at the physician office visit. The patient underwent the following laboratory tests and procedures: magnetic resonance imaging: (06Mar2021) a spinal tap which confirmed brain inflammation; sars-cov-2 test: (unspecified date) unknown result. Therapeutic measures were taken as a result of cranial nerve palsies multiple, noninfective encephalitis, deafness, headache, tinnitus, diplopia.   Clinical course: Patient experienced a very severe headache behind his right eye that continued for approximately 2 months along with loud high pitched ringing in both ears. Treated initially with an ENT who also diagnosed hearing loss in his right ear, prescribed steroids, and recommended that he should not receive the 2nd dose of the vaccine. Three weeks post vaccine he began to experience double-vision and treated with both a neurologist and an ophthalmologist. Patient received two MRIs and a spinal tap which confirmed brain inflammation. Based on these findings - with input from his initial ophthalmologist and a neuro-ophthalmologist - the diagnosis became cranial nerve inflammation/palsy. Patients symptoms had improved greatly and, thankfully, the double-vision resolved after three weeks and the headaches have diminished. Patient still suffer from very loud tinnitus, hearing loss, and headaches. No other vaccine was taken within four weeks of covid vaccine. Post vaccination patient was tested for covid.  No follow-up attempts are possible. No further information is expected.
