Pulmonary Thromboembolism from a Large Hemangioma in a 4 -Week-Old Infant

Abstract
A female infant with an extensive congenital hemangioma of the left knee region was treated medically for consumption coagulopathy; the hemangioma began to shrink, the coagulopathy improved, and the infant was clinically well when she died suddenly at the age of 4 weeks. The cause of death was a saddle pulmonary ihromboembolus which had originated in the hemangioma. This is the first documented case of fatal thromboembolism complicating a conservatively managed extensive neonatal hemangioma. Causes of neonatal thromboembolism are reviewed.
