Bone window imaging confirmed no fracture line (Figure 1A). Immediate CT examination showed right temporo-occipital EDH (the inner and outer diameters were 3 cm; the maximum diameter was >10 cm; the upper and lower diameters were 8.5 cm) with a leftward midline shift of 1 cm (Figure 1B). The third immediate CT examination showed bilateral frontal EDH (the inner and outer diameters of the right frontal part were 3.5 cm; the hematoma volume was >30 ml; the inner and outer diameters of the left frontal part were >2 cm; the hematoma volume was 20 ml) (Figure 1C). The postoperative CT scan showed satisfactory hematoma clearance, and the midline did not shift (Figure 1D).
