Summary
A “bright thalamus” is not uncommonly observed in cranial sonograms of asphyxiated neonates, but not those of older infants. Three infants, aged 9–14 months, developed acute onset of seizures and disturbance of consciousness after a minor prodromal illness. Bilateral thalamic infarcts were demonstrated by ultrasonography and CT. One patient expired from causes not directly related to the infarcts; the other two survived with severe neurological sequelae.
