Abstract Vascular channel of the frontal bone is a rare anatomical variant. This report describes a child who suffered from head injury with right parietal skull fracture and another suspicious fracture at the right frontal bone. Follow-up computed tomography showed persistent frontal "fracture" while the parietal fracture had resolved. Post-processing with 3D volume rendering showed that it was actually not a fracture. While there is no accessory frontal suture reported other than the metopic suture, the most likely cause for the radiolucency here is vascular channel of the frontal bone. Image post-processing is very helpful in doubtful situation, and should be considered in addition to axial images in our daily practice.
