颈部囊性病变的CT与超声诊断

目的探讨颈部囊性病变的CT与超声特征。方法搜集62例经手术病理证实的颈部囊性病变，均行CT和超声检查，回顾性分析其CT和超声特点。结果甲状舌管囊肿28例（45．16％），颈淋巴管瘤21例（33．87％），鳃裂囊肿13例（20．97％）。颈部囊性病变各有其好发部位，且病变CT和超声表现具有一定的特征。甲状舌管囊肿多见于颈中线附近、舌骨上下；淋巴管瘤多见于颈侧部、锁骨上，范围较广；鳃裂囊肿多见于中上侧颈部。甲状舌管囊肿及鳃裂囊肿呈单房性，淋巴管瘤多为多房性。结论CT和超声检查可清晰显示病变的大小、形态和延伸范围，多数能定性诊断，对颈部囊性病变具有重要的诊断和鉴别诊断价值。

Diagnosis of CT and Ultrasonography of Cystic Lesions at Neck

Objective To investigate CT and ultrasonographic manifestations of cervical cystic lesions.Methods CT and ultrasonographic findings of 62 cases with cervical lesions pathologically proved were retrospectively analyzed,ultrasonoraphy and CT scans in all cases.Results Thyroglossal duct cyst comprised 45.16%,lymphangioma 33.87% and branchial cleft cyst 20.97%.Each kind of the cystic lesions had its predilection site and both Ct and ultrasonic features.Most of the thyoglossal duct cyst were found closing to median live and hyoid bone;lymphangioma in lateral part or above the clavicle,and extended widely;branchial cleft cyst usually located at upper or middle part of the neck.Conclusion CT and ultrasonography could display the size,shape and extent of cervical cystic lesions clearly.CT and ultrasonography might be accurate and reliable in diagnosis and differential diagnosis of cervical cystic lesions.
