Computed tomography (CT) scan of an 18-year-old bicycle versus vehicle head-on patient. Computed tomography (CT) study conducted on an 18-year-old male patient upon the immediate deterioration of the initial presenting condition (GCS 13 to GCS 5 in four hours). This image highlights the presence of a large, acute, right-sided EDH, measuring 62.84 mm by 40.43 mm, as well as a 6-mm midline shift. The patient underwent an immediate craniotomy where the entirety of the EDH was removed. Intraoperatively, a nondisplaced frontotemporal skull fracture was noted. The patient responded positively to the surgical treatment and was discharged on postoperative day four with a complete resolution of the initial and developed conditions. EDH: epidural hematoma
