Lumbar laminectomy and washout of emphysematous osteomyelitis infection of the spine: illustrative case.

BACKGROUND

Emphysematous osteomyelitis (EO) is a rare, rapidly progressing infection characterized by gas within bones, leading to severe morbidity if untreated. In the spine, EO can cause significant bone destruction and instability, requiring urgent surgical and medical intervention. Early diagnosis and a multidisciplinary approach are crucial for effective management and improved patient outcomes.

OBSERVATIONS

The authors present a unique case of EO involving the lumbar spine in a 40-year-old male patient with a medical history of diabetes mellitus, hyperlipidemia, and hypertension. Magnetic resonance imaging and computed tomography revealed the formation of gas within the L4 vertebral body and spinal canal, which led to the diagnosis of EO. Blood cultures grew Streptococcus dysgalactiae. The patient underwent laminectomy, discectomy, and vertebral body abscess washout to prevent further spread of the infection and successfully recovered.

LESSONS

The authors report the first case of spinal EO caused by S. dysgalactiae, treated using laminectomy with debridement of the affected disc spaces. https://thejns.org/doi/10.3171/CASE24434.
