A soft lump on your newborn's head after birth can be alarming, but it is not always a serious problem. Cephalohematoma is a common birth-related condition that often heals on its own. In this guide, our expert explains its causes, symptoms, treatment, recovery, and signs that need medical attention.

The shape and appearance of a newborn's head can change during labour and delivery because of the pressure experienced during birth. Although many of these changes are temporary, some, such as cephalohematoma, may need closer observation before they resolve completely. Being aware of these changes can help parents understand their baby's condition and know when follow-up with a healthcare provider is important.

To help parents understand this condition, we spoke to Dr Rajat Grover, Senior Consultant, Department of Neonatology and Pediatrics, Cloudnine Group of Hospitals, East Delhi.

What Is Cephalohematoma?

Cephalohematoma is a birth-related swelling that appears as a soft or firm lump on a newborn's head. Cephalohematoma affects about 2 to 30 out of every 1,000 babies born.

It develops when a small amount of blood collects under the layer covering one of the skull bones during labour or delivery. The swelling usually becomes noticeable within a few hours after birth and stays on one side of the head.

Although it may look concerning, it does not affect the baby's brain and usually has a good outlook.

Difference Between Cephalohematoma and Normal Newborn Head Moulding

Although both can affect a newborn's head after birth, they are different.

  • Head moulding changes the overall shape of the baby's head because of pressure during birth and usually settles within a few days.
  • Cephalohematoma appears as a separate lump on the head and takes much longer to disappear, often several weeks.

Causes of Cephalohematoma in Newborns

Certain situations during childbirth can make it more likely to develop a cephalohematoma, including:

  • Prolonged labour: A longer labour may increase pressure on the baby's head.
  • Assisted vaginal delivery: Vacuum extraction or forceps can increase the risk.
  • Large baby (macrosomia): A larger baby may experience more pressure while passing through the birth canal.
  • First pregnancy: Labour is often longer in first-time mothers, which may slightly increase the risk.
  • Baby's position during birth: Some birth positions can place extra pressure on the head during delivery.

What Are the Symptoms of Cephalohematoma?

Common symptoms of cephalohematoma include:

  • A soft or firm lump on one side of the baby's head
  • The swelling has clear edges and stays in one area
  • The lump may feel firmer over time as it starts to heal
  • The skin over the swelling usually looks normal, without cuts or bruises
  • Most babies do not seem to be in pain because of the swelling

How Is Cephalohematoma Diagnosed?

Doctors usually diagnose cephalohematoma through:

  • Physical examination: Checking the size, location, and feel of the swelling.
  • Birth history: Understanding how the labour and delivery took place.
  • Imaging tests: An ultrasound, X-ray, or CT scan may be recommended if there is concern about a skull fracture or another birth-related injury.

How Is Cephalohematoma Treated?

According to Dr Rajat Grover, most babies with cephalohematoma do not need any specific treatment. Instead, doctors recommend regular follow-up to ensure it is resolving as expected.

Treatment may include:

  • Regular observation: The doctor monitors the swelling during follow-up visits.
  • No drainage: The lump should not be pressed or drained, as this can increase the risk of infection.
  • Managing complications: If complications such as jaundice or anaemia develop, they are treated appropriately.
  • Follow-up care: Parents may be advised to return for check-ups until the swelling has completely resolved.

Possible Complications of Cephalohematoma

Serious complications from cephalohematoma are uncommon, but some babies may need closer observation.

According to Dr Rajat Grover, Senior Consultant, Department of Neonatology and Pediatrics, Cloudnine Group of Hospitals, East Delhi:

"Babies with cephalohematoma may need monitoring because the breakdown of the collected blood can contribute to jaundice. Rarely, complications such as significant blood loss, infection, or an underlying skull fracture may occur."

Although these complications are uncommon, regular follow-up helps doctors identify and manage them early if they develop.

When to Seek Medical Care

Contact your baby's doctor if you notice any of the following:

  • The swelling becomes larger instead of smaller
  • The baby develops yellowing of the skin or eyes
  • The baby has a fever or seems unusually sleepy
  • The swelling becomes red, warm, or starts leaking fluid
  • The baby is feeding poorly or is difficult to wake
  • You are worried that the swelling is not improving as expected
While a lump on a newborn's head can be unsettling, cephalohematoma is usually manageable with appropriate medical care and follow-up. Staying informed about the condition and recognising warning signs can help parents make timely decisions if concerns arise.

FAQs on Soft Lump on Baby’s Head: Causes, Symptoms, Treatment, and Recovery

  1. Can a baby with cephalohematoma be breastfed normally?
    Yes. Cephalohematoma does not usually affect feeding, and most babies can breastfeed or bottle-feed as usual unless another medical condition is present.
  2. Can I apply oil or massage the swelling?
    No. Avoid massaging or applying oils, ointments, or home remedies to the lump unless advised by your baby's doctor.
  3. Will my baby need surgery for cephalohematoma?
    Surgery is rarely needed. Most babies recover without any surgical treatment, and doctors recommend observation unless complications develop.
