How to recognize a skull fracture in a baby
The signs of a skull fracture in a baby range from a simple soft swelling on the head to clear neurological emergencies, and because a newborn cannot tell you what hurts, the parent’s and clinician’s eyes do the work. Many fractures follow a forceps or vacuum delivery, so a baby with that history deserves especially careful observation. Some signs appear right away; others emerge over hours as bleeding develops beneath the bone.
This page describes what to look for. For the fracture types themselves, see the infant skull fracture hub; for what happens next, see healing and long-term effects.
Signs by fracture type
Different fractures announce themselves differently:
- Linear fracture: often the most subtle. There may be nothing more than a boggy swelling of the scalp or an overlying cephalohematoma (a firm collection of blood that does not cross the skull’s suture lines). The baby may otherwise seem well, which is exactly why a history of instrument delivery should lower the threshold to image.
- Depressed (“ping-pong”) fracture: a visible or palpable dent in the skull, like a dented table-tennis ball. It can sometimes be seen or felt directly.
- Diastatic fracture: widening along a suture line; may present as swelling near a suture and, later, as a growing lump if a growing fracture develops.
- Basilar fracture: the most dangerous, with distinctive signs: bruising behind the ear (Battle’s sign), bruising around the eyes (raccoon eyes), or clear fluid draining from the nose or ears (a cerebrospinal fluid leak). These demand emergency care.
Emergency red flags (possible brain involvement)
Regardless of fracture type, the following point to possible bleeding or brain injury and are emergencies:
- A bulging, tense, or full soft spot (fontanelle)
- Extreme sleepiness, difficulty waking, or unresponsiveness
- Repeated vomiting
- Seizures or abnormal, jerking movements
- A high-pitched, inconsolable cry
- Poor feeding or refusal to feed
- Unequal pupils, abnormal eye movements, or a fixed downward gaze
- Pale or bluish color, breathing pauses, or an unusually fast or slow heartbeat
Because a hematoma can enlarge over hours, a baby who looked fine at delivery can deteriorate later, which is why post-delivery monitoring matters as much as the delivery itself.
If your baby had a difficult forceps or vacuum delivery and these signs were missed or dismissed, that gap is what a records review examines. We will show you plainly what the timeline reveals, at no cost.
When to go to the ER
Seek emergency care immediately for any of the red-flag signs above, for a visible dent in the skull, for fluid leaking from the nose or ears, or for bruising behind the ears or around the eyes. When in doubt with a newborn’s head, err toward evaluation: the cost of a scan is small next to the cost of a missed bleed. Trust your instinct that something is wrong, and ask directly whether imaging is needed.
What doctors should check
For a baby at risk (a difficult delivery, instrument use, or a cephalohematoma) competent evaluation includes a careful head and neurological exam, measurement and observation of any swelling, assessment of the fontanelle, and a low threshold to order a CT scan when a fracture or intracranial bleeding is possible. CT is preferred because it shows both the bone and any bleeding underneath. Documented serial neurological checks in the hours after a difficult delivery are part of appropriate care; their absence in the records is one of the things a review looks for.
How infant skull fractures get missed
Fractures are missed in predictable ways: a cephalohematoma dismissed as “just a bump” without imaging; a baby with clear instrument-delivery risk factors sent home without a head exam or scan; early neurological signs attributed to normal newborn sleepiness; or a parent’s concern about a lump, poor feeding, or vomiting brushed aside. Each represents a point where the standard of care called for a closer look. See vacuum extraction injuries and forceps delivery injuries for the delivery decisions that precede these fractures.
Frequently asked questions
What does a skull fracture look like in a newborn?
It ranges from an invisible linear crack (sometimes signaled only by a cephalohematoma) to a visible dent (depressed fracture) or, with a basilar fracture, bruising behind the ears or around the eyes and fluid from the nose or ears. Neurological signs like a bulging soft spot, seizures, or extreme sleepiness point to possible brain involvement.
Can a baby have a skull fracture and seem fine?
Yes. Simple linear fractures often cause few symptoms, which is why a history of a difficult or instrument-assisted delivery should prompt careful evaluation even when the baby seems well. Bleeding underneath can also develop over hours.
How soon do symptoms of a skull fracture appear?
Some signs, like a dent or swelling, are present immediately. Signs of bleeding inside the skull can develop over hours, which is why monitoring after a difficult delivery is important.
Is a cephalohematoma a sign of a skull fracture?
It can be. A cephalohematoma is a collection of blood under the scalp’s covering, and while many occur without a fracture, they are associated with underlying linear fractures and should lower the threshold to image.
