Calcification of the cerebral falx is a physiologic calcification that usually presents few symptoms. Calcification of the cerebral fossa generally increases with age, and the incidence can reach more than 50% in people over 50 years of age. Calcifications in the falx of the brain mainly appear as focal calcifications along the falx in the form of linear or spindle-shaped or spherical calcifications, which may be due to abnormal deposition of calcium and phosphorus. Other areas are also prone to calcification, such as the basal ganglia bilaterally, which tends to show symmetrical calcification and is characterized by the rabbit ear sign. The choroid plexus and pineal region are also prone to calcification, which is physiologic and usually does not have obvious clinical symptoms.
