Hemangioma with consumptive coagulopathy (Kasabach-Merritt syndrome) detection by indium-111 oxine-labeled platelets.

A 4-year-old boy presented with consumptive coagulopathy suspected to be due to Kasabach-Merritt syndrome. Localization of homologous indium-111 platelets in the region of the right sacral ala confirmed that this was the site of disease and facilitated radiation treatment, which proved to be curative.
