It has been the impression of clinicians that pineal calcification is infrequent in Shiraz, Iran. In order to evaluate this clinical impression 2000 consecutive skul X-rays taken at Saadi Hospital, Shiraz, Iran, were reviewed for the presence of physiologic intracranial calcifications. The incidence of these clasifications in male and female in consecutive age groups of 10 years from 0 to over 70 years of age were assessed and compared with previous reports from other countries. The average incidence of pineal calcification for those over 20 years of age was 18.29% in this study compared with 55% in the U.S.A. The incidence of calcification in the choroid plexus and the falx cerebri was also considerably less than previously reported. The literature is reviewed and the possible causes for the geographical differences in the reported frequency of physiologic intracranial calcifications is discussed. It is possible that racial and dietary factors may be significant in the variation in the incidence of pineal and other cranial calcifications noted in different countries. Within a population group, age and sex are additional factors.
临床医生一直认为，伊朗设拉子地区松果体钙化情况并不常见。为评估这一临床印象，对伊朗设拉子萨迪医院连续拍摄的2000例颅骨X光片进行了回顾，以检查生理性颅内钙化的情况。评估了0至70岁以上连续10岁年龄组男性和女性中这些钙化的发生率，并与其他国家以前的报告进行了比较。在本研究中，20岁以上人群的松果体钙化平均发生率为18.29%，而在美国为55%。脉络丛和大脑镰的钙化发生率也明显低于以前的报告。本文对相关文献进行了综述，并讨论了所报道的生理性颅内钙化频率存在地理差异的可能原因。种族和饮食因素可能对不同国家松果体及其他颅骨钙化发生率的差异具有重要影响。在人群组中，年龄和性别是另外的影响因素。
