Congenital cardiovascular malformations (CCVM) are frequently associated with noncardiac malformations, often comprising a multiple malformation syndrome, but occurring infrequently in nonsyndromic systemic disease states such as neuroblastoma. As the most common malignancy in the first year of life, neuroblastoma presents as both clinically apparent and clinically unsuspected in situ tumors detected at autopsy. Neuroblastoma's association with CCVMs, especially conotruncal defects, suggests a possible common embryologic role for abnormal neural crest cell migration and development. We provide further documentation of this intriguing, albeit rare, association by reporting a boy with a prenatally detected complex CCVM (univentricular heart and dextro-transposition of the great arteries [d-TGA]) and congenital neuroblastoma.
