Skull & Cranial Anatomy
Parietal bone
A parietal bone is one of the two bones forming the upper sides and roof of the skull.
In short: Parietal bone
- Parietal encephaloceles occur through these bones.
- They form much of the top of the head.
- They meet at the sagittal suture.
- Some parietal lesions are small atretic encephaloceles.
What it is
It is one of the paired bones forming the upper sides and roof of the skull. The two parietal bones meet at the midline along the sagittal suture.
Understanding Parietal bone
The parietal bones form the convexity where parietal encephaloceles emerge, often as visible swellings on the top of the head. Some parietal encephaloceles are small atretic lesions, which are usually mild but still imaged to check for any deeper connection.
Why it matters
Understanding the parietal bone helps families locate top-of-head encephaloceles and recognize that they range from small atretic lesions to larger sacs, all evaluated with imaging.
