ABSTRACT

La osteomielitis vertebral piógena (OVP) es una localización poco frecuente (2-7%) Se confirma con el aislamiento de un microorganismo de una vértebra, disco intervertebral, absceso epidural o paravertebral. Se describe una serie de casos por la infrecuente presentación de esta enfermedad, que puede ser consulta inicial en los servicios de clínica médica y por su sintomatología inespecífica que supone una dificultad diagnóstica. Tanto la columna lumbar como la dorsal fueron los sitios más afectados. El dolor dorsolumbar y la paraparesia fueron los síntomas más frecuentes de presentación. En ocho pacientes se aislaron Staphylococcus aureus, en uno Escherichia coli y en el restante Haemophylus sp. Se observó leucocitosis sólo en tres pacientes, y en dos velocidad de sedimentación globular mayor de 100 mm/h. Los diez pacientes presentaron imágenes características de osteomielitis vertebral piógena en la resonancia nuclear magnética. Dentro de las complicaciones, los abscesos paravertebrales y epidurales fueron los más frecuentes (en cinco enfermos). Además, un paciente presentó empiema pleural. De los diez pacientes de esta serie, siete recibieron inicialmente tratamiento médico empírico y luego específico para el germen aislado. En los restantes el tratamiento fue guiado de acuerdo al antibiograma. A dos enfermos fue necesario realizarles laminectomía descompresiva por compromiso de partes blandas y a otros dos estabilización quirúrgica por inestabilidad espinal, observándose buena evolución en todos los casos. Esta serie demuestra que, ante un paciente con dolor dorsolumbar y síntomas neurológicos se deberá tener en cuenta esta entidad para evitar un retraso en el tratamiento.


Pyogenic osteomyelitis seldom affects the spine (2-7%). It is diagnosed by the isolation of a bacterial agent in the vertebral body, the intervertebral disks or from paravertebral or epidural abscesses. We report a retrospective study of ten patients who attended a medical clinic with this disease to emphasize its unusual presentation and difficult diagnosis. Lumbar and dorsal spine were the most common sites affected. Dorsolumbar pain and paraparesis were the most frequent symptoms. Staphylococcus aureus were isolated in eight patients, Escherichia coli in one and Haemophilus sp. in other Leukocytosis was observed in only three patients. Erythrocyte sedimentation rate was higher than 100 mm in the first hour in two patients. Typical images of pyogenic vertebral osteomyelitis were observed in all these patients with magnetic resonance imaging. The main complications were paravertebral and epidural abscesses that were found in five patients. One patient also presented an empyema, seven of them initially received empiric medical treatment, and later specific antibiotics according to the culture and sensitivity results. The rest of the patients were initially treated according to the sensitivity of the isolated germ. Surgical intervention was performed in two patients to drain soft tissue involvement, and in two other to stabilize the spine. All four surgical patients had a full recovery. This report is intended to point out that in patients with dorsolumbar pain and neurological symptoms pyogenic vertebral osteomyelitis is a possible diagnosis and has to be treated without delay.
