Delineation of Peripheral Bone Infarcts in a Child with a Rare Hemoglobinopathy (SOArab) and Purpura Fulminans: Case Report

A 27-month-old patient with .S'f >(,.„,, hemoglobinapathy complicated by purpura fulminons was studied with a:""Tc-pyrophosphate. The study showed an absence of radiotracer in the bones of both feet and the distal portions of both hands, along with an increased concentration of radiotracer prox imal to the regions of absent radiotracer. Subsequent amputation of the distal portions of ail four extremities was necessary because of dry gan grene. The amputation site in each extremity (selected on clinical grounds only) corresponded closely to the junction of absent and increased bone radiotracer, suggesting that bone imaging may be used as an aid in deter mining the extent of nonviable tissue in similar patients.
