Physiological and Radiological Implications of a Low Incidence of Pineal Calcification in Nigeria

Abstract

In a retrospective study of 952 skull X-rays taken in a few Lagos hospitals, it was found that the over-all incidence of calcification of the pineal gland was surprisingly low: 5.04% compared with the high incidence of 33-76 % reported in studies on other population groups. The incidence among the decades, and between the sexes, and the correlation with clinical diagnoses are analysed. The possible physiological and radiological implications are discussed.
