The pterion is the region where the frontal, parietal, temporal, and sphenoid bones join.[1] It is located on the side of the skull, just behind the temple. It is also considered to be the weakest part of the skull, which makes it clinically significant, as if there is a fracture around the pterion it could be accompanied by an epidural hematoma.
