OBJECTIVE
A rare case of an extraventricular colloid cyst located in the olfactory groove extending downward into the ethmoid sinus is presented. This is the second reported case in the world literature.
METHODS
A 56-year-old-woman presented with a lesion that was causing hyposmia and cerebrospinal fluid rhinorrhea. The lesion was an extraventricular colloid cyst displacing the left olfactory nerve downward and eroding into the left ethmoid sinus.
RESULTS
The lesion was excised, and the anterior skull base was reconstructed successfully via a unilateral subfrontal approach.
CONCLUSIONS
There were no complications, and the patient made a full recovery, with resolution of the cerebrospinal fluid rhinorrhea.
目的
报道一例罕见的嗅沟内延伸至筛窦的脑室外胶样囊肿，该病例为世界文献中的第二例报道。
方法
患者为 56 岁女性，因嗅觉减退和脑脊液鼻漏就诊。病变为脑室外胶样囊肿，向下推移左侧嗅神经并侵蚀左侧筛窦。
结果
通过单侧额下入路成功切除病变，重建前颅底。
结论
患者无并发症，完全恢复，脑脊液鼻漏得到解决。
