Abstract
INTRODUCTION: Acute hematogenous osteomyelitis may have significant morbidity and mortality if undiagnosed. Because it is uncommon in developed countries and has variable presentations, the patient may undergo several healthcare visits prior to diagnosis. CASE REPORT: We report the case of a 9-year-old male who presented with hip and knee pain with associated fevers and was found to have osteomyelitis and intraosseous abscess in the diaphysis of the right femur. He had multiple emergency department and outpatient visits before the ultimate diagnosis was made. He was treated with irrigation and debridement in addition to intravenous antibiotics. CONCLUSION: Pediatric acute hematogenous osteomyelitis can have subtle presentations, and this case illustrates some of the difficulties in making the diagnosis. This condition should be considered in the workup of a child with undifferentiated fever, pain, or decrease in mobility.
