Sinus pericranii

Hi kiddo! Sinus pericranii is when there's a little tube in your head that helps blood flow from one side to the other. It's kind of like a straw that moves blood around your head.

Usually, blood should travel through your veins, but in this case, it's taking a different path through the tube. This can happen if some of the veins in your head don't form correctly.

It's important to know about this because it can make doctors worried about other problems. But don't worry, your doctor will help you if you have this condition!
