A 65-year-old man complained of severe otalgia, occipital pain, hearing loss and otorrhea was referred to our hospital. Otoscopic examination demonstrated hyperemia and bulging of the left ear drum. The bacteria isolated from otorrhea was a mucoid type of Streptococcus pnemoniae. It was also penicillin-resistant Streptococcus pneumoniae (PRSP). The patient was diagnosed as having mucoid otitis media. Intravenous administration of piperacillin sodium (PIPC) diminished otalgia, occipital pain and otorrhea. However, the patient continued complain of hearing loss and a sensation of ear fullness. Due to acute sensorineural hearing loss, the patient was administered steroids. Nevertheless, bone conduction hearing loss persisted. This is the first report of otitis media demonstrating not only the mucoid type of Streptococcus pnemoniae but also PRSP.
