The presence of reactive bone in the intracranial surface is common in non-adults; however, these manifestations do not have a single explanation.This work aims to inform of the presence of endocranial lesions in fetal and infant individuals from a skeletal collection composed of remains with dates of death in the last quarter of the twentieth century;it also peruses to assess the frequency by age and its association with lesions in other skeletal elements.Of the total number of individuals in the collection, those in which it could be recognized some of the elements of the cranial vaultwere selected; the sample was finally comprised of 59 cases, with ages betweenfetal period and 1 year postpartum. The presence of endocranial lesions was registered in occipital, parietal and/or frontal and in other regions of the skeleton, mainly periosteal reactions. In order to analyze the frequencies by age the sample was subdivided into three groups based on chronological age,from death records: fetal, 0-6 months and 6-12 months. It was found that 59.3% of the cases have some kind of lesion in the endocranium, being common in the group of 0-6 months. The presence of endocranial lesions was found significantly associated with injuries to other parts of the skeleton. Several studies has related this to inflammation of the meninges, which may be associated with nonspecific or specific infections such as syphilis or tuberculosis. These lesions may also be related to vitamin deficiencies and subdural hemorrhages that can be traumatic or non-traumatic, the latter being of great importance in the diagnosis of child abuse cases.These hemorrhages have also been associated with cases of severe hypoxia in current studies of pediatric and perinatal pathology and some endocranial injuries have been proven as arteriovenous malformations in adult individuals.Since most vascularization and deposit of bone tissue is a normal manifestation in periods of rapid growth, it requires further investigation in relation to their type and distribution. Finally, the use of contemporary collections and the data from present biomedical research has the potential to contribute to the interpretation of findings from other historical periods.
