Finegoldia magna causing intramedullary thoracic spinal cord abscess in an infant.

Spinal intramedullary abscesses are rare and potentially devastating lesions. Infection is mostly caused by staphylococci. Anaerobes are rare and often polymicrobial. We report an unusual case of spinal cord intramedullary abscess in a 7-month-old infant with monomicrobial infection due to Finegoldia magna. She was found to have a missed congenital thoracic dermal sinus. The patient was treated with metronidazole and ceftriaxone for 8 weeks, and improvement of the infection was documented. Clinical awareness of patients at risk is crucial for early diagnosis and intervention. As detection methods continue to improve for Finegoldia magna, it is important to increase awareness of the pathogenic role of this organism.
