Abstract
The incidence of roentgenologically visible pineal gland calcification is approximately twice as common in American whites as in blacks, a difference that is very striking after age 40. Comparison of this finding with reports in the literature shows that the incidence of pineal gland calcification is slightly higher in American blacks than in indigenous Africans, probably due to racial mixture among the American blacks we studied. It appears that the low incidence of calcified pineal shadow already observed in the African has a constitutional basis.Keywords
