Abstract : Measurement of ventricular size is important in pediatric patients with hydrocephalus, especially those who are being followed with CSF shunts. 56 computed tomography (CT) and magnetic resonance imaging (MRI) scans from children aged 1 month to 1 year with hydrocephalus (HC), before and after treatment, were measured. Before measurement of thalamo-occipital distance (TOD) was performed only by ultrasound. We suggest implementation of TOD to other imaging modalities such as CT and MRI. Measurements were made in 56 patients with HC and 30 healthy children to determine the normal values and classify its severity. TOD was compared with Evans index and head circumference. We used the Pearson's correlation coefficients and correlations were further differentiated using a t-test statistic. The normal TOD is less than 3 cm. Distance between 3.0-3.7 cm is considered as mild, 3,71-4.4 cm moderate, more than 4,41 cm as severe degree of HC. The TOD measurement is a simple method of evaluating ventricular size in pediatric HC patients. The TOD showed high sensitivity (96%) and specificity (93%) in the diagnosis of HC in children
