Methicillin-resistant Staphylococcus aureus (MRSA)-associated juvenile osteomyelitis of mandible: a rare variant

Abstract

Mandibular osteomyelitis in paediatric population presents as painful swelling with progressive trismus. Often the aetiology for this form of progressive osteomyelitis is inconclusive. The infective aetiology in this condition is difficult to assign as bone tissue culture is found to be seldom positive. We present a case of an 11-year-old girl, with hearing and speech impairment, who presented with report of painful right-sided mandibular swelling with progressive trismus. Clinical, radiographic and histopathological findings were suggestive of sclerotic osteomyelitis. Bone tissue culture grew Methicillin-resistant Staphylococcus aureus, indicating a rare infective variant. Unlike the common belief, where osteomyelitic mandible needs a combination of medical and surgical management, our case was managed conservatively with only antibiotic therapy. Our patient responded well to the treatment with reduction in pain and gradual improvement in the mouth opening. Radiographically the mandibular involvement also showed complete regression.
