## **Core Concept**
Increased intracranial tension in infants can lead to changes visible on a skull X-ray due to the open fontanelles and sutures. One key sign is the separation of sutures, which occurs because the growing brain pushes against the cranial bones, causing them to move apart.

## **Why the Correct Answer is Right**
The correct answer, , represents the "separation of sutures." This is a recognized radiological sign of increased intracranial pressure (ICP) in infants. The sutures of the infant skull are not yet fused, allowing for the cranial bones to move in response to increased pressure from within. As the intracranial pressure increases, it can cause the sutures to separate, which is visible on a skull X-ray.

## **Why Each Wrong Option is Incorrect**
- **Option A:** - This option does not accurately describe a recognized sign of increased intracranial tension.
- **Option B:** - This option is not a valid radiological sign associated with increased intracranial pressure in infants.
- **Option D:** - This option does not represent a known consequence of increased intracranial tension visible on a skull X-ray.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that in infants, the presence of separated sutures on a skull X-ray can be an indicator of increased intracranial pressure. This is particularly important because infants and young children have open fontanelles and sutures, allowing for some degree of cranial expansion in response to increased intracranial pressure, which can sometimes mask the symptoms.

## **Correct Answer:** . Separation of sutures.
