Table 1 Baseline characteristics and CT/MRI findings of five patients with traumatic brain injury and unilateral third nerve injury
Patient # | Trauma mechanism | Age/sex | GCS | Initial CT trauma findings relative to the injured third nerve | CT/MRI abnormalities in the region of the affected third nerve | Surgical intervention | Follow- up time (months) | Pupillary function outcome |
|---|---|---|---|---|---|---|---|---|

2 | Ground level fall | 67/M | 15 | Perimesencephalic bleed | CT: blood adjacent to the third nerve | None | 2 | Normal: R pupil function returns rapidly |
3 | Bicycle accident | 12/M | 3 | Contralateral BG hemorrhage | MRI: enhancement of cisternal portion | Left sided evacuation of BG bleed | 15 | Abnormal: R pupil dilated and unresponsive |
4 | Thrown from horse | 35/F | 13 | None | MRI: enhancement of cisternal portion | None | 4 | Abnormal: L pupil anisocoria, dilated, and unresponsive |
5 | Motorcycle accident | 59/F | 3 | R CCF, orbital rims fractured | CT: CCF | Endovascular obliteration of CCF | 2 | Abnormal: R pupil dilated and unresponsive |
