What is Cephalohematoma and explain in detail?
A cephalohaematoma is a hemorrhage of blood between the skull and the periosteum of any age human, including a newborn baby secondary to rupture of blood vessels crossing the periosteum.  Because the swelling is subperiosteal, its boundaries are limited by the individual bones, in contrast to a caput succedaneum.

Symptoms and signs
Swelling appears after 2-3 days after birth. If severe the child may develop jaundice, anemia or hypotension.  In some cases it may be an indication of a linear skull fracture or be at risk of an infection leading to osteomyelitis or meningitis. The swelling of a cephalohematoma takes weeks to resolve as the blood clot is slowly absorbed from the periphery towards the centre. In time the swelling hardens (calcification) leaving a relatively softer centre so that it appears as a depressed fracture
