No acute intracranial pathology or space occupying lesion is seen. Incidental finding of persistent metopic suture with frontal sinus agenesis; the remaining visualized paranasal sinuses as well as bilateral mastoid air cells are well-aerated and clear.
Case Discussion
Metopic suture, commonly obliterated by the age of 7 years can persist as an anatomical variant and is of little clinical significance except in cases of trauma where it can be misinterpreted as a frontal bone fracture. It may be associated with frontal sinus agenesis (as in this case) or hypoplasia.
