Background: Current radiological diagnosis of various cerebral dystrophy requires subjective judgment for comparing with the normal brain ventricular system dimensions, thereby knowledge of morphometric and size of normal ventricular system of brain is of paramount importance to understand these changes. Methods: For the present perspective study, computerized tomography (CT) of 500 patients (Males-339 and Females-161) were studied for the measurements of lateral ventricle, third ventricle and fourth ventricle and it was statistically analyzed. Results: The antero posterior extent of the body of the lateral ventricles on the right side was 75.23 ± 6.8 mm and on the left side was 71.02±7.78 mm; the length of the frontal horns on the right side was 28.2± 2.72 mm and on the left side was 27.7±2.9 mm respectively. The width and height of the fourth ventricle were 11.87±1.08 and 8.9±1.5 mm whereas width of the third ventricle was 5.58±2.10 mm. Conclusion: The present study has defined the morphometric measurements of the Brain ventricular system (BVS) such as lateral ventricles, third ventricle, and fourth ventricle of the brain of normal individuals which has clinical correlations in diagnosis and for appropriate treatment.
