Abstract：
Laryngeal schwannoma is a rare type of neurogenous tumour with a non-specific presentation. We present a case of a middle-aged man with issues of hoarseness, globus sensation and intermittent episodes of throat pain. The Hopkins examination showed right vocal fold irregularity with fullness in the right ventricle. The contrast-enhanced CT neck revealed an ill-defined lesion with contrast uptake extending into the paraglottic region with no neck node involvement. Considering the clinical presentation of hoarseness, throat pain and globus with imaging revealing contrast enhancement of lesion, direct laryngoscopy and biopsy were planned to rule out malignancy. Intraoperatively, a well-defined submucosal capsulated swelling became apparent after incision and dissection of the mucosa over the right vocal fold. A complete excision of the swelling was done with microlaryngeal instruments without tracheostomy. The histopathological report was suggestive of schwannoma. The literature review discusses clinical presentation, location, imaging features and management strategy.
摘要：
喉神经鞘瘤是一种罕见的神经源性肿瘤，具有非特异性表现。我们介绍了一个中年男子的声音嘶哑问题，球状感觉和间歇性咽喉疼痛发作。霍普金斯检查显示右声带不规则，右心室充满。对比增强CT颈部显示病变不明确，对比剂摄取延伸至声门旁区域，无颈淋巴结受累。考虑到声音嘶哑的临床表现，咽喉疼痛和球形成像显示病变的对比增强，计划直接喉镜检查和活检以排除恶性肿瘤。术中,在右声带上的粘膜切开和解剖后，明显出现了明确的粘膜下包囊性肿胀。使用微喉器械完全切除肿胀，无需气管造口术。组织病理学报告提示神经鞘瘤。文献综述讨论了临床表现，location,影像学特点和管理策略。
