Scintigraphic demonstration of hemangioma in neck.

The use of serial Tc-99m labeled RBC imaging in demonstration of a hemangioma of neck is reported. The abnormal and tortuous vascular connections of a hemangioma show a characteristic delayed filling-in of the radiolabeled blood pool producing the pathogonomic blood flow/blood pool mismatch. Described classically for hepatic hemangiomas, this scintigraphic pattern holds true for hemangiomas at other sites, in this instance a neck hemangioma.
