1 A, Axial noncontrast CT at the level of the internal capsules demonstrates a left frontal extra-axial hematoma (arrow). A, Axial noncontrast CT at the level of the internal capsules demonstrates a left frontal extra-axial hematoma (arrow). There is also diffuse sulcal effacement. B, Nondisplaced right-sided parietal calvarial fracture is present on the preoperative CT (arrow). Right frontal and temporal calvarial fractures were also present (not shown). Coronal suture diastasis is seen on the left. C, Following left-sided decompressive craniectomy, a large, predominantly parietal, DEDH developed adjacent to the patient's right parietal bone fracture. D, A decompressive craniectomy was subsequently performed on the right side with evacuation of DEDH and significant improvement in mass effect. J.F. Talbott et al.
