Neonatal Scalp Conditions: Caput Succedaneum, Subgaleal Hemorrhage, and Cephalhematoma

This article discusses neonatal scalp conditions, specifically focusing on Caput Succedaneum, Subgaleal Hemorrhage, and Cephalhematoma. These conditions are related to the newborn's scalp and can involve different areas under the skin.

Caput Succedaneum

Caput Succedaneum is characterized by an edematous collection of serosanguinous fluid in the subcutaneous layer of the scalp. This condition is caused by the application of mechanical force, such as during vacuum extraction deliveries. Caput Succedaneum is typically recognized by a diffuse, boggy swelling over the scalp, and it can extend beyond the suture lines. Infants with Caput Succedaneum may experience rapid resolution of the swelling, while those with larger hemorrhages may require treatment, which includes monitoring for signs of infection, dehydration, or anemic status.

Subgaleal Hemorrhage

Subgaleal Hemorrhage (SGH) is an accumulation of blood in the subaponeurotic space, caused by the rupture of the emissary veins, which lie in this area. This condition is rare but potentially fatal and can lead to severe complications, such as hypovolemic shock, acute anemia, coagulopathy, and even death. SGH presents with a tender, fluctuant scalp swelling that indistinctly crosses the suture lines. As a potential space, the subaponeurotic space can accommodate a large volume of blood, potentially collecting up to 260 mL in neonates. Early detection and intervention are crucial for managing SGH, as it carries serious risks.

Cephalhematoma

Cephalhematoma is a collection of blood between the skull and its periosteum, typically located in the parietal or occipital bone. It is defined by a bulge on the newborn's head that does not cross cranial suture lines. Cephalhematomas usually become evident within the first day to three days after birth. They can be firm at first but may become more fluctuant with time. Additional tests, such as skull x-rays or computed tomography (CT) scans of the head, may be requested to rule out underlying skull fractures.

In summary, neonatal scalp conditions, including Caput Succedaneum, Subgaleal Hemorrhage, and Cephalhematoma, are related to various aspects of the neonate's scalp. Understanding these conditions is essential for proper diagnosis, treatment, and management to minimize the risks associated with each condition.
