Incidence of Physiological Pineal Gland and Choroid Plexus Calcifications in Cranio-Cerebral Computed Tomograms in Douala, Cameroon

s Background Intracranial calcifications are veritable radiological pointer to pathologies. Therefore there is need to differentiate physiological and pathological calcifications. Objective Todetemine the incidence of physiological intracranial calcifications and relationship to age and sex. Materials And Methods A cross sectional descriptive study of the computed tomograms (CT) of the brain was done from 8/4/09 to 18/10/2009 using a Schumadzu CT scan machine with continuous rotationalsystem. Data was analysed using SSPS3. Results 132 patients were studied with 75 males and 57 females. Age range is 0-89. The highest studied population is in the 40-49 years with 38(28.78%) patients These 116 had a total of 136 seperate calcifications due to co-existent calcifications. No calcifications wasseen in patients less than 9years of age. The number of patients with choroid plexus calcifications (75) exceeds the number of patients with pineal gland calcifications (61). This corresponds to incidence of 56.8% for choroid plexus calcifications and 46.2% for pineal gland calcifications. In terms of total numberof calcifications, it is shared into 55.15% for choroid and 44.85% for pineal calcifications. the incidence of pineal gland calcification is 46.21% while choroid plexus calcification is 56.82%. Both calcifications aremore common in males than females. In choroid plexus calcifications, the incidence of calcifications in males is greater than females by 14.67% whereas in pineal gland calcifications, male incidence is greaterthan female incidence by 18.04%. Conclusion Choroid plexus calcification is more than pineal gland calcifications and no calcification was seen before 9 years.
