Which scalp condition involves swelling that can extend across the entire scalp and may be life-threatening due to blood loss and shock?

• A. Subgaleal hemorrhage
• B. Caput succedaneum
• C. Cephalohematoma
• D. Molding

Answer: (A)

This describes a subgaleal hemorrhage. Bleeding into the subgaleal space beneath the galea aponeurotica can spread widely across the entire scalp, because that space is a large potential area for blood to accumulate. In a newborn, a substantial amount of blood can collect there, leading to rapid blood loss, poor perfusion, and shock. That combination makes it life-threatening if not recognized and treated quickly. Understand that other scalp findings behave differently. Caput succedaneum is superficial swelling from birth trauma that crosses the scalp, including across any sutures, but it is usually mild and resolves within a few days without significant blood loss. Cephalohematoma is a subperiosteal bleed tucked between a skull bone and its periosteum; it remains confined by the sutures and does not cross them, and while it can take time to resolve, it doesn't typically cause rapid blood loss or shock. Molding refers to temporary overlapping of skull bones during birth and does not involve a fluid-filled scalp swelling. Recognition hinges on a rapidly enlarging, boggy, diffuse scalp swelling that can extend across the scalp and is accompanied by signs of hypovolemia as bleeding continues. Prompt fluid and blood resuscitation, careful monitoring, and assessment for ongoing hemorrhage are essential.
