Elevated soft tissue activity in early but not delayed phase of bone scan in Klippel-Trenaunay syndrome.

Triple-phase bone scan is commonly used in the diagnosis of osteomyelitis. Elevated bone tracer activity in early but not delayed phase of the study favors cellulitis over osteomyelitis. We reported that Klippel-Trenaunay syndrome, a congenital disorder characterized by malformations of the capillary, venous, and lymphatic systems, can have images similar to cellulitis on triple-phase bone scan.
