Role of power Doppler sonography in early diagnosis of osteomyelitis in children.

We describe 2 children complaining of leg pain associated with elevated C-reactive protein levels in whom power Doppler (PD) sonography suggested the diagnosis of early osteomyelitis. PD sonography detected increased blood flow that resulted in a high-intensity signal area adjacent to the symptomatic tibia surface. Antibiotic therapy led to prompt improvement. These cases suggest that PD sonography is useful in the evaluation of possible early osteomyelitis in children. (c) 2008 Wiley Periodicals, Inc. J Clin Ultrasound, 2008.
