Introduction: Knowledge of the ventricular size is important for the initial and precise diagnosis of hydrocephalus. Evans index is a valuable parameter in diagnosis of the NPH, follow up cases of VP shunt, dementia and many other pathologies. Therefore, having a baseline reference data of the Evan's index will be helpful in a wide range of clinical pathologies. Our aim was to establish normal values for Evans index in a Kashmiri indian population as none has been found in the Kashmiri medical literature. Material and Methods: Axial computerized tomographic brain scans of 300 normal subjects were reviewed. EI was measured as the linear ratio of the widest anterior horn width of the cerebral lateral ventricles to the widest inner diameter of the skull. Results: Of them, 185(61.66%) of the patients were males and 115 (38.33%) were females; their ages ranged from 6 to 96 years with a mean age of 47 years. The images were acquired using a 16 slice CT machine. The mean value for Evans index for the studied population was 0.264 ± 0.03. The EI increased with age and it was slightly higher among males. The difference in Evans value in males and females was not statistically significant. Individuals above 60 years old had the highest Evans values in both sexes. Conclusion: This study established the ranges of normal value for Evans index in a kashmiri population. It agrees with the diagnostic cutoff value of > 0.3 for hydrocephalus and it compares well with that of the Caucasians.
