Intracranial schwannomas that do not involve major cranial nerves in the posterior fossa are uncommon, especially if they are not associated with neurofibromatosis type II (NF-2). Subfrontal olfactory groove schwannomas are extremely rare. We report a cystic schwannoma arising from the olfactory groove in a 38-year-old Caucasian male who presented with headache, vomiting and visual impairment. We briefly review the pertinent literature, stress the distinctive clinical and neuroradiological findings and discuss the surgical planning and theories about the pathogenesis of schwannomas in this unusual location.
不涉及后颅窝主要颅神经的颅内神经鞘瘤并不常见，尤其是那些与II型神经纤维瘤病（NF - 2）无关的。额下嗅沟神经鞘瘤极为罕见。我们报告了一例38岁白人男性患者，其嗅沟处出现囊性神经鞘瘤，表现为头痛、呕吐和视力障碍。我们简要回顾相关文献，强调其独特的临床和神经放射学表现，并讨论手术规划以及关于该不寻常部位神经鞘瘤发病机制的理论。
