Caput succedaneum

Dr Dan J Bell and Radswiki et al.

Caput succedaneum is a manifestation of birth trauma, and it consists of a subcutaneous serosanguineous fluid collection beneath the newborn's scalp. The fluid collection is extra-periosteal. It may be imaged with ultrasound, CT, or MRI.

Caput succedaneum results from pressure on the presenting part of the skull against the dilating cervix. It extends across the midline and over suture lines and is associated with head moulding.

Caput succedaneum does not usually cause any complication and usually resolves over the first few days. Management is expectant.
