The Wormian bones are supernumerary bony cranial structures. Their origin is multifactorial, being many times related to metabolic bone diseases. In this article, the objective is to describe the finding of an interparietal Wormian bone in the context of a clinical case of multiple skull fracture due to trauma. Case report: a female pediatric patient, with no medical history, suffered a moderate traumatic brain injury. She was evaluated at the medical emergency department, finding a left parietal cephalohematoma in the clinical exam. A computed tomography was performed. It showed two linear non-displaced fractures in both parietal and occipital bones, associated with an incidental Wormian interparietal bone (os incarum). There were no intra-axial lesions. The patient was hospitalized and had a good clinical evolution until the time of discharge. At eight months follow-up, no complications were found, showing radiological improvement. Conclusion: Wormian bones constitute cranial anatomical variations. Their incidental finding in imaging studies can cause diagnostic difficulties in certain situations, as may occur in head trauma with the presence of fractures, so it is important to know their relevant characteristics.
