Physiological intracranial calcifications without a relationship with a particular disease or pathology and accepted as normal, are seen most common in pineal gland, choroid plexus, habenular commissure basal ganglia, dura and arachnoid. Computed tomography (CT) is the most sensitive radiological method in detection of intracranial calcifications. In our study 401 unenhanced cranial CT that obtained between April 2009 and August 2009, are evaluated as retrospectively for physiological intracranial calcification fields. Of the 401 cases, 69,3% had choroid plexus calcification, 66,1% had pineal gland calcification, 35,2% had habenular commissure calcification, 25,2 % had other (basal ganglia, dura and arachnoid) calcifications. Of the cases 51,9% had pineal gland and choroid plexus, 28,7% had pineal gland and habenular commissure, 28,4% had choroid plexus and habenular commissure calcilfication co-existence. Significant increase in the prevalence of the pineal gland, choroid plexus and habenular commissure calcifications was found with increased age (p<0.001). Also co-existence of pineal gland and choroid plexus, pineal gland and habenular commissure, choroid plexus and habenular commissure was significant (p<0.001).
