Blood cyst Blood cyst: The lesion was an incidental finding on the tricuspid valve of a 4-month-old infant who died of unrelated causes. The large size of the cyst (4 mm) and the age of the patient are unusual for congenital blood cysts, which are usually less than 2 mm in diameter and regress by 2 months of age.
