Patient Data
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
There are bilateral bony protruberances from the parietal bones, which are seen to be due to thickened calvarium on the source images. This is the typical appearance of ossified cephalohematomas.
Case Discussion
A cephalohematoma is a traumatic subperiosteal hematoma which is bounded by the periosteum and cannot cross sutures. This distinguishes it from a subgaleal hematoma, which does cross sutures. Cephalohematomas occur in 1–2% of live births. The incidence increases after forceps extraction. Cephalohematomas usually gradually incorporate into the calvaria by ossification. Cephalohematomas may be unilateral or bilateral.
