Sequential CT scans were evaluated in four term infants with severe asphyxia, who subsequently developed neurodevelopmental sequelae. The initial CT scans performed within the first week of life showed poor visualization of the ventricles, diffuse but mild low density in the cerebral hemispheres and the falx image. In two of them, remarkably low density was seen in the basal ganglia and thalami in the second CT scans. The last CT scans demonstrated multicystic encephalomalasia in one case and brain atrophy with thalamic high density due to postichemic hypervascularity in the other. Of the other two cases, one showed low density in the fronto‐temporal region in the initial CT scan and brain atrophy in the sequential scans. The other showed only transient periventricular low density. In conclusion, the morphologic changes seen in sequential CT scans continue until at least two months after birth and neonatal scans alone may not be useful for predicting the outcome.
