The most common neurologic sign in neonatal period is Convulsion , based on the condition of each neonate with seizure the radiologic survey will carry out. In this study the role of brain- CT scan without contrast was evaluated for neonates with seizures.

This was a cross-section descriptive study on 80 neonates with seizure admitted in NICU of Ekbatan hospital Hamadan during 2002-2003. The brain Ct-scan without contrast was done for all of them , the radiologic reports were recorded on special forms , and evaluated with statistically methods.

65% of neonates had abnormal CT : Intracranial hemorrhage in 19 cases (23.7%) , Local ischemic lesions in 18 cases (22.5%) , Hypoxic- ischemic encephalopathy in 15 cases (18.7%) , Brain dysgenesis in 8 cases (10%) and combined forms in 18 cases (22.5%).

            In this study abnormal CT scan findings were noticeable , most of the seizure occurred at 24-72 hrs after birth and association with difficult labor was statistically meaningful (P<0.05). Because the difficult delivery and hypoxia are participating factors of neonatal seizures , perhaps the proper or inappropriate delivery and perinatal intervention is a factor for interpretation of findings of this study.
