Which statement correctly differentiates caput succedaneum from cephalohematoma?

Which statement correctly differentiates caput succedaneum from cephalohematoma?

• A. Caput crosses sutures; cephalohematoma does not cross sutures
• B. Cephalohematoma crosses sutures; caput does not cross sutures
• C. Both cross sutures
• D. Neither crosses sutures

Answer: (A)

Differentiating these neonatal scalp swellings hinges on where the swelling sits in relation to the skull sutures. Caput succedaneum is diffuse swelling of the scalp tissue that extends across the scalp and can cross the sutures because it’s essentially edema of the soft tissues over the skull. It’s commonly present at birth from pressure during delivery and generally resolves within a day or two without intervention. Cephalohematoma, on the other hand, is a subperiosteal bleed between the skull bone and its periosteum. It is confined by the suture lines and does not cross them, so it remains localized to a single bone area. It may take several days to develop after birth and can take weeks to resolve; it can also be associated with mild anemia or hyperbilirubinemia as the blood product breaks down. So, the key distinguishing feature is that caput succedaneum crosses sutures, while cephalohematoma does not cross sutures.
