Cephalohematoma
photo by Janelle Aby, MD
Cephalohematoma is a collection of blood under the periosteum of a skull bone. Because of its location, it is impossible for cephalohematoma to cross suture lines. If more than one bone is affected, there will be a separation between the two areas at the suture line as seen in this photo -- the sagittal suture separates the bilateral parietal cephalohematomas. On palpation, these areas feel fluctuent.
