Glossopharyngeal schwannomas are rare tumors. Clinical and radiologic presentation closely resembles those of vestibular schwannomas. Their clinical presentation varies from vestibulocochlear dysfunction to glossopharyngeal and vagal nerve dysfunction.
We report a case of a small glossopharyngeal schwannoma presenting with intractable recurrent sudden episodes of vomiting that subsided after tumor resection. To our knowledge, this is the only case in the literature of glossopharyngeal schwannoma presenting with nerve irritation in the form of intractable emesis.
Small glossopharyngeal schwannomas can present with irritative symptoms of the ninth cranial nerve causing vomiting refractory to medical treatment. Intracranial imaging should be considered in the investigation of unexplained intractable vomiting even if the gross neurologic examination is normal.
舌咽神经鞘瘤较为罕见。其临床表现和影像学特征与前庭神经鞘瘤相似。它们的临床表现从前庭耳蜗功能障碍到舌咽神经和迷走神经功能障碍不等。
我们报告了一例小的舌咽神经鞘瘤病例，表现为难以治疗的复发性突发性呕吐，肿瘤切除后呕吐缓解。据我们所知，这是文献中唯一一例以难以治疗的呕吐形式表现出神经刺激的舌咽神经鞘瘤病例。
小的舌咽神经鞘瘤可表现为第九颅神经的刺激性症状，导致呕吐难以治疗。即使大体神经系统检查正常，对于不明原因的难以治疗的呕吐，也应考虑进行颅内影像学检查。
