an edematous swelling formed on the presenting portion of the scalp of an infant during birth; the effusion overlies the periosteum; contrasted with cephalhematoma, in which the effusion lies under the periosteum and consists of blood rather than serum.
Etymology: L, caput, head, succeder, to replace
a localized pitting edema in the scalp of a fetus that may overlie sutures of the skull. It is usually formed during labor as a result of the circular pressure of the cervix on the fetal occiput. On vaginal examination the swelling may be mistaken for unruptured membranes. If the caput enlarges appreciably during labor, it may cause an erroneous impression of fetal descent on successive examinations. At birth the baby's head may appear markedly deformed, but the swelling begins to resolve immediately and is usually gone in a few days. Compare cephalhematoma, molding.
