Glossopharyngeal (that is, cranial nerve IX) schwannomas are extremely rare nerve sheath tumors that frequently mimic the more common vestibular schwannoma in their clinical as well as radiographic presentation. Although rare in adults, this tumor has not been reported in a child. The authors report the case of a 10-year-old boy who presented with several months of unilateral hearing loss. He was found to have a large right cerebellopontine angle tumor. Given the boy's primary complaint of hearing loss and the appearance of the lesion on imaging, the tumor was initially believed to be a schwannoma of the vestibular nerve. It was found intraoperatively, however, to originate from the glossopharyngeal nerve. To the authors' knowledge, this is the first reported case of a glossopharyngeal schwannoma in a child.
舌咽神经(即第九对脑神经)鞘瘤是极其罕见的神经鞘瘤,在临床和影像学表现上常类似于更常见的前庭神经鞘瘤。虽然在成人中罕见,但该肿瘤在儿童中尚未见报道。作者报告了一名10岁男孩的病例,该男孩出现数月的单侧听力丧失。他被发现患有一个巨大的右侧小脑桥脑角肿瘤。鉴于该男孩听力丧失的主要症状以及病变在影像学上的表现,肿瘤最初被认为是前庭神经鞘瘤。然而,术中发现它起源于舌咽神经。据作者所知,这是首例报道的儿童舌咽神经鞘瘤病例。
