Fetal Cardiac Rhabdomyoma With Hydrops Fetalis

Rhabdomyoma is the most common cardiac tumor in fetuses, often associated with the tuberous sclerosis complex, especially when multiple tumors and a positive family history of tuberous sclerosis are noted. The tumor is often benign and has a tendency to regress but may increase in size until the early third trimester. Fetal cardiac rhabdomyoma complicated by hydrops fetalis and leading to fetal death is rare. We report 2 cases of fetal cardiac rhabdomyoma with hydrops fetalis and provide a review of the literature.
