Persistent metopic suture seen as an irregular line dividing the frontal bone at the midline (incidental finding).
Biparietal burr holes for bilateral chronic subdural hematoma.
Case Discussion
The metopic suture is usually obliterated by about 7 years of age, but in rare cases, it can persist as an anatomical variant of little clinical significance. It should not be mistaken for a vertical frontal bone fracture, therefore it is important to be aware of this anatomical variant.
