摘要
目的:分析颈部囊性病变的CT特性。材料与方法:回顾性分析43例经手术证实的颈部囊性病变,其中(1)淋巴结病变14例;(2)脓肿3例;(3)涎腺病变7例;(4)甲状舌骨囊肿4例;(5)神经鞘瘤2例;(6)甲状腺病变3例;(7)鳃裂囊肿3例;(8)淋巴管瘤4例;(9)喉气囊肿2例;(10)表皮样囊肿1例。结果:特定的解剖部位及影像学表现对颈部囊性肿块的诊断及鉴别诊断有明确的价值;如鳃裂囊肿多起源于第二鳃裂位于下颌角下胸锁乳突肌中1/3的前缘或下方;甲舌囊肿主要位于颈前中线舌骨水平上下,皮样囊肿多位于口底正中等。结论:CT检查能准确评价病变的性质和位置,对诊断和术前制定方案有重要价值。
Purpose： To investigate CT findings of cystic masses of the neck. Materials and Methods： 43 cases with cystic neck lesions including lymphadenopathyl4, abscesses 3, salivary lesions 7. thyroglossal duct cystic 4, nerve sheath 2, thyropathy 3, branchial cleft cysts3, lymphangiomas 4, laryngoceles 2 epidermoid cysts 1. Results： The precise anatomical location and imaging appeavance are important for accurate diagnosis and for mulating the differential diagnosis of cystic lesions in the neck. Branchial cleft cysts are mainly located anterior inferior to the middle third portion of the stemocleidomastoid muscle, thyroglossal dust cysts are mainly located in the anterior midline portion of the neck at the level of the hyoid bone, dermoid cyst are plesented in the floor of the mouth. Conclusion： CT can provide essential informations in evaluating the nafure and location of the cystic masses of neck. which is of significance for diagnosis and preoperative planning.
