A 65-year-old woman was transferred to our hospital with fever, shoulder pain, and back pain. She was diagnosed as purulent facet joint arthritis (L1-2 spine) and omarthritis. Streptococcus pneumoniae was detected from the blood, and a diagnosis of invasive pneumococcal disease (IPD) was made. Ceftriaxone 4 g/day was used for 4 weeks and the condition improved. IPD can occur even in immunocompetent persons.
