Objective: The goal of this study was to review our series of spinal epidural empyema diagnosed in the last 20 years and review the literature regarding the pathogenesis, diagnosis and treatment of these lesions.
Patients and methods: This is a retrospective study over 14 patients diagnosed of spinal epidural empyema. We review the epidemiological data, clinical symptoms, laboratory and imaging data, the treatment regimen and the results.
Results: Fourteen patients, 7 males and 7 females, with an age range from 8 to 76 years (mean 48.9) were identified. The first symptom was localized back/ neck pain in 12 patients and the mean duration of symptoms was 9.3 days. Erythrocyte sedimentation rate (ESR) was elevated in all patients; peripheral leukocyte count was elevated in 13 cases (92.9%). Site of spinal epidural empyemas was distributed along the axis but in 11 cases the location was thoracic. Thirteen patients had surgery for debridement and spinal decompression and one patient was treated successfully with antibiotics alone.
Conclusions: Patients with localized back pain and fever who are at risk for developing such empyemas with elevation of white blood cells and increased ESR, should have an immediate magnetic resonance imaging sean. Urgent surgical drainage and antibiotic use are the treatment of choice in order to prevent irreversible neurological deficits. Nonsurgical treatment should be reserved for poor surgical candidates and patients without neurological deficits.
