Cephalohematoma

Neonatal cephalohematoma, also known as subperiosteal hematoma, is often caused by birth trauma that ruptures subperiosteal blood vessels, leading to blood accumulation localized beneath the periosteum. It typically presents with clear boundaries, does not cross suture lines, and has a fluctuating feel. Cephalohematomas are most commonly found in the parietal and occipital regions, manifesting as localized, well-defined masses.
