A Case of Legionella pneumophila With Hearing Loss Improved by Antimicrobial Therapy

Legionella pneumophila is known to cause various complications, but hearing loss is rarely reported. A 59-year-old woman, healthy by nature, developed a fever and cough and was hospitalized with a diagnosis of L. pneumophila. She had symptoms of hearing loss since admission, and examination revealed bilateral sensorineural hearing loss. However, since this did not interfere with her daily life, she was followed up. After treatment with pazufloxacin and levofloxacin for pneumonia, her hearing loss symptoms improved along with the improvement of her pneumonia. This case suggests that L. pneumophila may be associated with sensorineural hearing loss.
