[Spondylodiscitis: Diagnosis and medium-long term follow up of 18 cases].
BACKGROUND
Spondylodiscitis is an uncommon disease in children. It is often misdiagnosed or the diagnosis is made late in the course of illness.


OBJECTIVE
To review the clinical, analytical and radiological characteristics of children with spondylodiscitis in the Materno-Infantil Hospital of Malaga.


METHODS
Retrospective cohort study on children diagnosed with spondylodiscitis, during a period of 11 years.


RESULTS
Eighteen patients were included in the study. Spondylodiscitis was more frequent in patients younger than 3 years old and older than 12 years old. The average time of delay in diagnosis was 26.9 days. In 8 cases the diagnosis was missed initially. Three clinical patterns appeared: in children under 3 years of age, refusing to walk and sit (100%) and irritability (42%); between 3 and 12 years of age, limb (100%) and abdominal pain (100%); in adolescents, back pain (75%). Fever was present in 38% of the cases, and low-grade fever in 8 (44%). A total of 50% of the patients had a moderate leucocytosis, and a slight increase in ESR; the most frequent location was L3-L4. X-ray diagnosis was pathological in 88% of the cases. The initial MRI diagnosed 100% of the cases. In addition, nerve roots damage (5 cases), inflammatory masses/paravertebral abscesses (5), epidural abscess (1) and psoas abscesses (2) were detected. A total of 94% of the children received antibiotics and 100% of the children underwent immobilization. All patients recovered early after the beginning of treatment, with the exception of those affected by psoas abscesses. The radiological follow-up was done in 17 patients (12 by MRI). After a mean of 14 months (rank 1-48), persistent diminution of disc space was seen in 100% of the children, and improvement of soft-tissue inflammation. Clinically (follow-up only in 11 patients) all patients regained normal mobility and only 27% had moderate pain.


CONCLUSIONS
Spondylodiscitis, whose delay in the diagnosis is frequent, is a serious illness. Complications include abscesses and nerve root damage. MRI is the study of choice to determine the extension to neighbouring tissues.
