BACKGROUND Subgaleal abscesses and skull osteomyelitis are very uncomm
on since the introduction of antibiotics. Eikenella corrodens infectio
n is extremely rare in childhood and has never been reported in calvar
ial osteomyelitis. METHODS We present a previously healthy 9-year-old
boy, with a history of frontal contusion without injury, who developed
E corrodens osteomyelitis of the skull. The radiographic findings are
reviewed, including skull films and computed tomographic scans. The p
atient underwent surgical debridement of the lesion, as well as system
ic medical therapy with amoxicillin. We review the medical and surgica
l therapy for such lesions. The differential diagnosis of a posttrauma
tic scalp swelling is also reviewed. RESULTS Good resolution after deb
ridement and antibiotic therapy is reported. CONCLUSIONS Surgical inte
rvention is emphasized for the removal of bony sequestrum and nonviabl
e bone while maintaining an intact dura.
