Intratumoral consumption of indium-111-labeled platelets in a child with splenic hemangioma and thrombocytopenia

The authors report Kasabach-Merritt syndrome (KMS) in a patient with thromb ocytopenia and splenic hemangioma. A 13-month-old boy with a history of ane mia, thrombocytopenia, and abdominal mass was admitted to the hospital. The scintigraphic studies showed that a large mass contiguous to the spleen wa s responsible for the platelet uptake. After partial splenectomy, the plate let count returned to normal. This report of KMS in a child with splenic he mangioma suggests that the scintigraphic studies are mandatory to confirm d iagnosis. Indium-111-labeled platelets are useful in identifying hemangioma tous sequestration of platelets in patients with thrombocytopenia.
