Cephalohematoma

Michael P. D'Alessandro, M.D.
Peer Review Status: Internally Peer Reviewed

Etiology/Pathophysiology:
Common sequelae of birth trauma, frequently associated with forceps delivery. Is a subperiosteal calvarial hemorrhage and therefore the bleeding is limited by suture lines. Heals via progressive resorption over several months, and is treated via observation.

Pathology:
Not applicable

Imaging Findings:
Usually seen over the parietal regions and underlying fractures are rare. Peripheral calcification of the hematoma is seen by 10-14 days and eventually the entire hematoma is outlined by calcification. Resolution takes several months and there is often some degree of remnant calvarial thickening.

• Caput succedaneum - subcutaneous collection of blood not limited by sutural margins.
• Subgaleal hematoma - bleeding into the subaponeurotic or subgaleal portions of scalp that also extends beyond suture margins but is much larger than a caput succedaneum.
