Osteomyelitis in an Unusual Location With an Atypical Presentation: A Case Report and Review of the Literature of Scapular Osteomyelitis in Pediatric Patients

Pseudoparalysis in an infant with otitis media: an evolving presentation of scapular osteomyelitis

A female infant presented to an Irish hospital with a 4-day history of fever, irritability and reduced oral intake. Initial inflammatory markers were significantly elevated, an erythematous tympanic membrane was noted on examination and an initial diagnosis of acute otitis media was made. By the third hospital day, the infant was noted to be irritable when being lifted up; pseudoparalysis of the right upper limb was observed. A radiograph of the right shoulder was normal; MRI identified acute scapular osteomyelitis with subperiosteal abscess formation. The child underwent 3 washout procedures and received 6 weeks of antibiotic therapy, with full clinical recovery at 3 months. This case highlights the importance of remaining flexible in the context of an evolving presentation and recognising hallmarks of musculoskeletal infection, fever, localised pain and pseudoparalysis. Additionally, we review the literature to highlight clues in diagnosis, treatment and outcome for paediatric acute scapular osteomyelitis.
