Explain anatomical basis of cephalhematoma

Accumulation of blood deep to the pericranium/periosteal layer of scalp due to injury is known as cephalhematoma. The swelling  is localized over the particular bone and takes the shape of the bone involved, because  the pericranium is loosely attached over the bones except at the sutural lines where it is connected to the endosteum via sutural ligaments. The hematoma is bound by suture lines  and the swelling has well-defined margins. Cephalhematoma is often seen in the parietal region. It may take 4-7 days to disappear.
