cephalhematoma
[sef′əlhē′mətō′mə, -hem′ətō′mə]
swelling caused by subcutaneous bleeding and accumulation of blood. It may begin to form in the scalp of a fetus during labor and enlarge slowly in the first few days after birth. It is usually a result of trauma, often caused by forceps. Large cephalhematomas may become infected, require surgical drainage, and take several months to resolve. Also called cephalhaematoma. Compare caput succedaneum, molding.
cephalhematoma [sef″al-he″mah-to´mah]
a localized effusion of blood beneath the periosteum of the skull of a newborn, due to disruption of the vessels during birth. Cephalhematoma, in contrast to caput succedaneum, does not cross cranial suture lines. It is firmer to the touch than an edematous area: it feels like a water-filled balloon. Cephalhematoma usually appears on the second or third day after birth and disappears within weeks or months.
