Chronic recurrent multifocal osteomyelitis: a case report and review of literature.
BACKGROUND
Chronic recurrent multifocal osteomyelitis (CRMO) is a rare condition of largely unknown aetiology and pathogenesis with variable clinical and radiological features. There are no reports on CRMO to the best of our knowledge; in the West African sub region.


OBJECTIVE
To present a case and review the literature on chronic recurrent multifocal osteomyelitis.


METHODS
A 13-year-old male presented with a three-year history of recurrent discharging right thigh sinus and an 11-day history of a left shoulder swelling with discharging sinus. Detailed history was obtained and physical examination and radiological and microbiological tests carried out before treatments.


RESULTS
There were periodic exacerbations of pain, swelling and discharge over affected areas. He had a short limb gait and shoulder asymmetry. His left shoulder was warm, erythematous and there was decreased range of movement in all directions. Investigations revealed an erythrycyte sedimentation rate (ESR) of 150mm/hr. Wound swabs taken at different times from the right thigh and shoulder sinuses revealed no growth. Radiographs of the left arm, right thigh and hip showed features consistent with chronic osteomyelitis. There were associated destruction of the left hip and soft tissues welling in the left shoulder. He was principally treated with non-steroidal anti-inflammatory drugs (NSAIDs) , antibiotics and dressing of sinuses for three months and had only mild relief of clinical features but no improvement in radiological picture.


CONCLUSIONS
Chronic recurrent multifocal osteomyelitis is a diagnosis of exclusion which is usually under diagnosed because amongst other things, not much is known about it. Successful treatment is difficult to achieve, though some authors have reported good results with combined medical and surgical treatment.
