The bleeding from a cephalohematoma is due to the rupture of which blood vessels?
Rupture of small blood vessels under the periosteum (sub-periosteal) are responsible for cephalohematomas.
A cephalohematoma is confined to the underlying bone and does not cross the _____ or _______.
Suture lines or midline
What is the most common risk factor for the development of a cephalohematoma?
Instrument assisted delivery (with forceps or vacuum)
1) A well-defined convex, calcified lesion measuring approximately 4.5 cm in maximum transverse diameter and 6 mm in maximum thickness in the left parietal region; is most compatible with a calcified cephalohematoma. The cephalohematoma does not cross the sagittal suture, as expected.
2) Both orbits and bone density appear normal, and no other lesion is visualized.
