What is a less common, yet possible outcome of untreated cephalhematoma?

Jaundice is a less common, yet possible outcome of untreated cephalhematoma. Cephalhematoma involves bleeding between the skull and the periosteum, which can occur as a result of birth trauma. The accumulation of blood in the area can lead to the breakdown of red blood cells, causing an increase in bilirubin levels in the newborn's body. This process can result in jaundice, characterized by a yellowing of the skin and eyes due to elevated bilirubin levels.

While other complications such as permanent neurological damage, lowered IQ scores, and developmental delays may be considered in severe or complex cases, they are typically associated with more significant neurological impairment or other complications rather than cephalhematoma alone. In contrast, jaundice specifically ties back to the physiological changes that occur due to the blood accumulation in cephalhematoma, making it a direct and plausible outcome of this condition if not addressed properly.
