Penetrating brain injury (PBI) is a rare type of traumatic brain injury, which accounts for 0.4% of all head trauma cases. In this study, we describe a 14-year-old male adolescent who sustained a transorbital penetrating injury caused by a fencing knife. Although the patient visited the hospital after the foreign body had been removed, we diagnosed a PBI based on identification of a linear injury trajectory extending from an orbital roof fracture to the contralateral parietal lobe, using three-dimensional reconstruction of the hemorrhage. The patient fully recovered after conservative treatment. We hope that sharing our experience will serve as a guideline for the clinical management of PBI.
