Emphysematous Osteomyelitis of the Spine: A Case Report and Literature Review

Emphysematous osteomyelitis is a rare but potentially fatal infection. It is caused by gas-forming organisms and is characterized by the presence of intraosseous gas. A 75-year-old woman with untreated diabetes mellitus presented with difficulty in moving and anorexia. Laboratory studies revealed inflammation, a urinary infection, and diabetic ketoacidosis. Klebsiella pneumoniae was detected in both urine and blood cultures. Computed tomography and magnetic resonance imaging revealed emphysematous lesions in the paravertebral soft tissue, spinal canal, and iliopsoas muscle, with intraosseous gas at L1 and L2. These findings led to a diagnosis of emphysematous osteomyelitis. We herein review 35 reported cases of emphysematous osteomyelitis including our case.
