Brain calcifications may be present in a wide range of neuropsychiatric,
infectious traumatic, neoplastic and endocrine conditions, associated with motor
and cognitive symptoms. They are often considered "physiologic" or
pathologic.OBJECTIVETo determine the prevalence of brain calcifications in a Brazilian
cohort.METHODS1898 consecutive patients underwent skull CTs, comprising 836 men and 1062
women.RESULTSAmong all 1898 patients, 333 (197 women and 136 men) presented with brain
calcifications, representing an overall prevalence of 17.54%. The prevalence
in the female group was 18.54% versus 16.26% in the male group.CONCLUSIONSA growth in incidental findings on CT scans are likely as these exams become
more widely available. However, a current debate between radiologists and
regulators is set to redefine the CT usage, especially in the United States
and the United Kingdom, considering new norms for use and radiation dosage
per exam.
