Abstract
Background
Chronic recurrent multifocal osteomyelitis (CRMO) is not a well known disorder among
nonpediatricians. The aim of this study is to retrospectively evaluate the clinical
outcomes of twenty-two CRMO patients presenting to two referral centres.
Methods
This retrospective study included twenty-two children (12 males, 10 females; mean
age 13 years; range 7–17 years). The diagnosis was based on clinical, radiological,
and pathological findings. Data were retrieved from hospital charts.
Results
The mean delay in diagnosis was 26 months (range, 0–96 months). The mean follow-up
after diagnosis was 27.4 months (range, 6–47 months). Symptoms included pain, limping,
local swelling, morning stiffness, and fever. 18 patients had multifocal and 4 patients
had unifocal disease. Bone lesions were detected with whole-body or local MRI (Magnetic
Resonance Imaging). The mean number of bone lesions was 2.5 (range, 1–8). Ten cases
underwent biopsy to exclude malignancy and infection. Prior to diagnosis, cast immobilization
or curettage was erroneously performed in four patients. One patient suffered from
vertebral compression fracture. There is no growth disturbance or deformity in any
patient.
Conclusion
This study demonstrated that early recognition of the disease can be improved by using
Bristol criteria which should be evaluated by a multidisciplinary team rather than
one single specialist. In this way, the reliability of these criteria is improved
and the treatment could be given earlier with decreased delay in diagnosis. This multidisciplinary
approach is also important for decision for biopsy, timely aggressive medical treatment,
and follow-up of the disease to minimise possible complications.
