Dents in the skull are abnormal and can indicate a serious medical condition. I first noticed dents in my skull when my hair began thinning and shedding at the onset of menopause.

The largest dent is on the top right side of my skull. It measures about an inch long and half an inch deep. A smaller dent is right behind it. Smaller dents are along my hairline.

The dents and skull depressions concerned me enough to make an appointment with my doctor. She told me not to worry since I didn't have any symptoms and my bloodwork was normal.

The dents in my head are not the result of head trauma. I would remember if I was hit in the head with a hammer or a similar blunt object.

What Causes Dents in the Skull?

According to, the number 1 cause of dents in the skull is trauma. Other causes are covered below.

1. Head Trauma

Car accidents, falls, or severe blows to the head can cause what’s called a depressed fracture in your skull. A depressed fracture means that a part of your skull has been crushed in toward your brain. This kind of injury requires emergency medical treatment.

2. Vitamin A Toxicity

Excessive levels of Vitamin A in the blood can cause skull indentations, particularly in children who don't eat a well-balanced diet. Vitamin A is essential for healthy skin, hair, eyes, and more. Too much Vitamin A is called hypervitaminosis and can lead to the softening of bone in the skull which can causes dents and depressions.


Signs & Symptoms of Vitamin A toxicity include:

    Irritable and drowsy or sleepy
    Abdominal pain
    Nausea or vomiting

Chronic (longterm) signs & symptoms of hypervitaminosis include:

    Skin changes (rough, dry and peels easily)

If you have these signs and symptoms, consult with your doctor or healthcare professional immediately.

Gorham's disease is a rare condition that causes bone causes bone loss in your skull, leading to a visible dent in some cases.

4. Cancer

There are case reports of skull depressions that have led doctors to a diagnosis of cancer. These cases are rare, but "bone-destructive" cancers (such as multiple myeloma) can cause skull depressions and skull irregularities.

5. Congenital skull indentation

Some babies are born with an indentation in their skull. These indentations can be caused by the birth process or forceps used by doctors to extract the baby.

6. Meningitis

Meningitis is the inflammation of the Meninges or the membrane layer that covers your brain to protect it. Meningitis is a life-threatening condition if not treated promptly on time.

Signs & Symptoms of meningitis include:

    High fever
    Neck pain or stiffness in the neck (considered an emergency)
    Photophobia or eyes sensitivity to light
    Nausea, vomiting due to increased pressure on the brain

    Sandra what do you have on knuckleheads? ?????

    Just before noon today there was a shooting at a Baton Rouge Walmart. Deputies arrived to learn that shots had been fired in the store. The verbal altercation was at the customer service desk and led to the shooting. Both of the suspects had hand guns. Deputies arrested one suspect, but the other fled off in a light-colored sedan. The person who was injured was an innocent bystander, who drove his self to the hospital.

    Thank you so much! My daughter has a dent in the top of her head. It was not always there. YOu can't see it because of her hair.
    I know it is there because I do her hair. OMG... I need to research the reasons. It is definitely not from injury.
