cephalohematoma
Pronunciation: sef-ah-low-hee-mah-TOH-mah
Collection of blood between the skull and periosteum, typically occurring after traumatic delivery.
Full Definition
A cephalohematoma is a subperiosteal hematoma that develops when blood vessels rupture between the skull bone and its overlying periosteum, most commonly during difficult deliveries. Unlike caput succedaneum, cephalohematomas are bounded by suture lines and do not cross them. The hematoma typically appears hours after birth, enlarges over the first few days, then gradually resolves over weeks to months. Complications may include hyperbilirubinemia from blood breakdown and rarely underlying skull fractures. This finding appears in newborn examination records, delivery notes, and pediatric follow-up documentation.
Usage
Usage note: Note the 'cephalo' prefix and 'hematoma' spelling. Distinguish from caput succedaneum, which crosses suture lines.
