A case of conjoined twins.
Among 56,249 maternities in the Collaborative Perinatal Project, 615 were twin maternities. One of these resulted in stillborn thoracoomphalopagus MZ female twins with multiple cardiovascular, alimentary and other malformations. The case is of further interest in that the mother had a surgically removed brain tumor in childhood and exhibited neurological symptoms and bizarre behavior before and during pregnancy. Drugs and treatments which she received during pregnancy are not known to be teratogenic.
