摘　　要：目的探讨喉部少见病变的临床特征及CT表现,提高对其认识及CT诊断能力。方法回顾性分析2013年6月至2022年2月经我院手术及病理证实的10例喉部少见病变的临床及CT影像资料,包括喉淀粉样变3例、喉神经内分泌癌2例、喉多形性腺瘤2例、喉血管瘤2例及喉浆细胞瘤1例,并术后随访观察。结果喉淀粉样变主要表现为声嘶,CT表现为结节状软组织密度,坏死少见,增强呈轻度渐进性强化,周围结构无侵犯。喉神经内分泌癌主要表现为喉部异物感,CT表现为不规则团块样软组织密度,增强呈明显不均匀强化,颈部可有增大淋巴结转移。喉多形性腺瘤主要表现为胸闷、咳嗽伴异物感,CT表现为结节状软组织影,呈稍低密度,增强呈轻中度持续性强化,无颈部淋巴结转移。喉血管瘤主要表现为异物感伴声嘶,CT表现为形态规则、边缘光滑并呈明显持续性强化的软组织结节。喉浆细胞瘤主要表现为声嘶,CT表现为大病灶、小坏死、增强呈中低度强化。结论喉部少见病变有一定的临床表现及相对特征性的CT影像特点,掌握这些病变的临床表现及CT特征,对临床诊断及鉴别诊断可提供重要帮助,确诊仍需临床及术后病理。Objective To investigate the clinical characteristics and CT manifestations of rare laryngeal lesions,and to improve the understanding and CT diagnostic ability. Methods The clinical and CT imaging data of 10 cases with laryngeal rare lesions confirmed by surgery and pathology in our hospital from June 2013 to February 2022 were retrospectively analyzed, including 3 cases with laryngeal amyloidosis, 2 cases with laryngeal neuroendocrine carcino-ma, 2 cases with laryngeal pleomorphic adenoma, 2 cases with laryngeal hemangioma and 1 case with laryngeal plasmacytoma. Results Laryngeal amyloidosis was mainly manifested as hoarseness. CT showed nodular soft tissue density, rare necrosis, mild progressive enhancement and no invasion of surrounding structures. The main clinical manifestation of the patients with laryngeal neuroendocrine carcinoma was laryngeal foreign body sensation. CT showed irregular mass-like soft tissue density, and the enhancement is significantly unevenly enhanced. Lymph node metastasis could be increased in the neck. Laryngeal pleomorphic adenoma was mainly characterized by chest tightness, cough and foreign body sensation. CT showed nodular soft tissue shadow with slightly low density, and enhanced with mild to moderate persistent enhancement without cervical lymph node metastasis. Laryngeal hemangioma mainly showed foreign body sensation with hoarseness, and CT showed soft tissue nodules with regular shape, smooth edge and obvious persistent enhancement. Laryngeal plasmacytoma mainly showed hoarseness, CT showed large lesions, small necrosis,enhancement showed moderate to low enhancement. Conclusion Laryngeal rare lesions have certain clinical manifestations and relatively characteristic CT imaging characteristics. Mastering the clinical manifestations and CT characteristics of these lesions can provide important help for diagnosis and differential diagnosis. The diagnosis still needs clinical and postoperative pathology.
