Methods: The study was carried out in the Department of Forensic Medicine and Toxicology in association with Trauma center of S.P. Medical College and Associated Group of Hospitals, Bikaner, after institutional ethical clearance.

Results: Out of 100 cases 88.00% were male and 12% were female. Maximum cases (38.00%) were from 21-30 year age group and minimum cases (3.00%) were from 0-10 year age group. The most interesting factor which came across during the study was the contribution of 89.00% cases of the Traffic Accidents. Skull fracture was observed in 75 cases at autopsy and the same finding observed only 67 cases in CT scan, making disparity in 10.66%.Extradural haemorrhage (EDH) was observed in 14 cases at autopsy, and same was documented only in 12 cases on CT scan, thus making disparity in 14.28% cases. Subdural haemorrhages (SDH) were observed in 68 cases at autopsy and 60 cases on CT scan making disparity in 11.76% cases. Subarachnoid haemorrhages (SAH) were observed in 79 cases at autopsy and 60 cases on CT scan making disparity in 24.05% cases. Intracerebral haemorrhage (ICH) was observed in 10 cases at autopsy and 4 cases on CT scan making disparity in 60.00% cases. Brain oedema was observed in 26 cases at autopsy, and same was documented only in 18 cases on CT scan, thus making disparity in 30.76% cases. Cortical contusions were observed in 49 cases at autopsy and 39 cases on CT scan making disparity in 20.40% cases. Laceration of brain was observed in 2 cases but was not observed in any case on CT scan.

Conclusion: It was observed that although CT scan is a useful tool for the diagnosis of various kinds of lesions of head injury, autopsy was found to be more effective in detecting them.
