All are true about cephalhematoma except:
**Core Concept**
Cephalhematoma is a type of subperiosteal hemorrhage that occurs in the skull, typically in newborns. It is characterized by the accumulation of blood between the periosteum and the bone, usually as a result of trauma during delivery.
**Why the Correct Answer is Right**
Cephalhematoma is distinct from other types of subcutaneous hemorrhages, such as caput succedaneum, because it is limited to a specific area of the scalp and does not cross suture lines. This is due to the fact that the periosteum is adherent to the bone and does not allow the blood to spread beyond the affected area. Cephalhematoma typically presents as a firm, fluctuant mass that is usually confined to one side of the skull.
