Rheumatoid meningitis (RM) is a rare central nervous system disorder in patients with rheumatoid arthritis. A 72-year-old man with a history of rheumatoid arthritis developed sensorineural hearing loss on the left side 3 months ago ; he subsequently exhibited neurological symptoms, including dizziness, nausea, and impaired consciousness. He was diagnosed with RM after excluding malignancies and infections via systemic assessments, which included imaging and cerebrospinal fluid examinations. He was treated with corticosteroids, which improved his neurological symptoms despite the remaining hearing impairment. To the best of our knowledge, only four cases of sensorineural hearing loss in RM, including our patient, have been reported. Furthermore, this report demonstrates hearing impairment as a crucial symptom in RM diagnosis.
