| The yellow staining in the brain of a neonate is known as kernicterus. There is a coronal section of medulla on the left and cerebral hemisphere on the right demonstrating kernicterus in deep grey matter of hemisphere and brain stem. Increased unconjugated bilirubin, which accounts for the kernicterus, is toxic to the brain tissue. Kernicterus is more likely to occur with prematurity, low birth weight, and increased bilirubin levels. [Image contributed by Jeannette J. Townsend, MD, University of Utah] |
