Abstract
Objective:Intracranial calcifications underlie certain brain diseases which may be de novo or systemic. But calclfications un-connected to pathologies are classified physiological.Aim:To evaluate physiological intracranial calcifications in Douala with establishment of earliest age range of detection.Materials and Methods:Prospective study of brain computed tomograms was done from April to October 2009 using Schumadzu CT Scan machine. Axial, reconstructed and bone window images as well Hounsfield unit measurements were used for final evaluations. Results were analysed with SSPS 3.Results:132 patients with 75 males and 57 females were studied and 163 separate calcifications were identified due to co-existent calcifications. The highest calcification was in choroid plexi, constituiting 56.82% of the studied population. This was followed by pineal gland. Both were commonly co-existent with advancing age. These calcifications were first seen at 10-19years. No type of physiological intracranial calcification was seen below age 10. The least calcification of 0.76% of population was in dentate nucleus.Conclusion:No intra-cranial physiological calcifications started earlier than 9years in Douala, a city in Cameroon, Central Africa.
Highlights
S calcifications as .MRI cannot reliably rule out or determine the presence of calcifications (Glo & Zee, 1998, pp542-58 (Sarmiento de La Iglesia et al, 2006, pp19-26)
This age range had the highest number of intra-cranial calcifications of 58 (35.58%) of the total number of 163 intracranial calcifications detected in this study
The highest number of calcifications of 75, constituting 46.01% of total number of detected calcifications and 56.82% of total studied populations was seen in the choroid plexus, with 44 calcifications in males and 31 in females
Summary
S calcifications as .MRI cannot reliably rule out or determine the presence of calcifications (Glo & Zee, 1998, pp542 (Sarmiento de La Iglesia et al, 2006, pp). The magnetic resonance imaging findings for intracranial calcifications previously demonstrated at CT are variable and unspecific (Glo & Zee, 1998, pp542 (Sarmiento de La Iglesia et al, 2006, pp). The most frequent appearance of intracranial calcifications on T1W sequence is an area isointense with the cerebral cortex while most frequent appearance on T2W sequence is focus of hypointensit (Sarmiento de La Iglesia et al, 2006, pp19-26)
