It has been suggested that chorioangiomas should be added to the list of causes of elevated maternal serum alpha-fetoprotein levels. We undertook a review of maternal serum alpha-fetoprotein levels in chorioangiomas histologically diagnosed in our department, and a review of the literature. Maternal serum alpha-fetoprotein level was elevated in only 1 of our 11 cases of chorioangioma. To date, there have been 14 case reports of chorioangiomas in which maternal serum alpha-fetoprotein levels have been recorded; 12 of these were associated with elevated maternal serum alpha-fetoprotein levels. We consider that, although chorioangiomas may be a cause of elevated maternal serum alpha-fetoprotein levels, it is likely to be infrequently a cause of such elevations in our population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
