Figure 1.

(a) Cone beam CT scan axial view of a 36-year-old male without evidence of brain calcifications as a negative control for comparison with images to follow. Note the lack of brain tissue detail and noise in this scan and scans to follow. (b) Sagittal view of a 16-year-old male with a small hyperdense mass (arrow) representing a typical midline brain calcification in the pineal/habenular region. (c) Axial view of a 76-year-old female with bilateral faint radio-opacities (arrows) representing petroclinoid ligament calcifications. (d) Axial view of a 56-year-old male demonstrating bilateral faint radio-opacities (arrows) that represent choroid plexus calcifications. Note the pineal/habenular calcification in the midline just medial and superior to these bilateral calcifications
