Morphometric Study Of Posterior Horn Of Lateral Ventricle And Its Correlation With Age And Side: A Ct Study

ABSTRACT

Enlargement of lateral ventricle is most striking feature after sixth decade of life. Regression of brain is normalageing process. But there are marked individual variations in this process. Lateral ventricular contours arerelatively constant, except for the occipital horns. Two major changes that may occur in elderly individualwithout neurologic deficits is enlargement of ventricles and cortical atrophy. This study is focusing on thechanges in posterior horn of lateral ventricle in different age groups. Aim of this study is to statistically analysethe length of the posterior horn of lateral ventricle in human and to correlate the changes in relation to age andside. Method: The CT images of 150 adult individuals (age group 20-80yrs) was studied in both males andfemales. Length of posterior horn of lateral ventricle was measured using dicomworks software. Result: Meanvalue of length of the posterior horn increases on both sides as the age increases. Values are larger in 61-80years. In relation to the side, the length of posterior horn is greater on the left side as compared to the right side.
