We report a patient with a cystic structure in the nasopharynx mimicking a Tornwaldt's cyst, which was felt to represent a different entity owing to the lack of the distinct features of a typical Tornwaldt's cyst. It was associated with a bony cleft in the basiocciput that was considered to be a canalis basilaris medianus (CBM), thought to represent an embryological vestige of the cephalic end of the notochord along its course within the basiocciput.
我们报告了一例鼻咽部囊性结构的患者，该结构类似于 Tornwaldt 囊肿，但由于缺乏典型 Tornwaldt 囊肿的特征，我们认为这是一种不同的实体。该囊性结构与基底部的骨性裂隙相关，我们考虑该裂隙为正中基底动脉管（CBM），被认为是沿基底部走行的脊索颅端的胚胎学遗迹。
