Two cases of intracranial penetration of a plastic or wooden chopstick via the optic canal are described. CT scans showed the chopsticks as linear hypodense structures in the suprasellar cistern contiguous with the optic canal. In one case, MR imaging was performed, which clearly depicted the foreign body and adjacent brain structures. Although they are extremely rare, transorbital intracranial penetrating injuries via the optic canal require physicians' awareness.
本文描述了两例塑料或木质筷子经视神经管穿入颅内的病例。CT扫描显示筷子为与视神经管相连的鞍上池内的线状低密度结构。其中1例进行了磁共振成像（MR成像），清晰显示了异物及邻近脑结构。尽管经视神经管的经眶颅内穿透伤极为罕见，但仍需医生提高警惕。
