cephalohematoma
Pronunciation: sef-uh-loh-hee-muh-TOH-muh
A localized collection of blood between the skull and periosteum in newborns, typically caused by birth trauma during delivery.
Full Definition
Cephalohematoma is a subperiosteal hematoma that occurs in approximately 2-3% of newborns, most commonly following instrumental deliveries or prolonged labor. Unlike caput succedaneum, it does not cross suture lines and appears as a firm, fluctuant swelling that develops hours after birth. The condition usually resolves spontaneously within weeks to months, though large hematomas may contribute to neonatal jaundice as the blood is reabsorbed.
Usage
Usage note: Often confused with caput succedaneum in medical documentation; editors should verify that the described characteristics match the correct condition.
