METHICILLIN-SENSITIVE STAPHYLOCOCCUS AUREUS BACTEREMIA AND MENINGITIS ASSOCIATED WITH SPINAL AND PSOAS MUSCLE ABSCESS – CASE REPORT

Abstract

Methicillin-sensitive Staphylococcus aureus (MSSA) can cause a range of severe infections, including bacteremia and meningitis. While MSSA-related bacteremia and meningitis are serious on their own, they can also be associated with complex complications such as intraspinal and psoas abscesses. We report a case of a 72-year-old male with symptoms including lower back pain, leg weakness, malaise, fever and headache. Initial laboratory results showed leucocythosis, hyponatriemia and elevated CRP, while cerebrospinal fluid analysis indicated significant pleocytosis and neutrophilia. After admission, three blood cultures were obtained, all of which isolated MSSA. During hospitalization, a CT scan of the thorax and MR of the spine were performed, revealing bilateral pleural effusion, L5-S1 intraspinal abscess, and an abscess in the ileopsoas muscle. After 6 weeks of antibiotic therapy, a follow-up MRI was performed, which showed regression of the abscesses. This case underscores the severe complications of Staphylococcus aureus infection, including meningitis, sepsis and abscesses. Effective management relies on prompt diagnosis, comprehensive evaluation, and targeted antibiotic therapy. The patient’s positive outcome highlights the importance of early recognition and tailored treatment in complex infections.
