【摘要】 目的:探讨MSCT对儿童颈部囊状淋巴管瘤的诊断价值。方法:回顾性分析15例经病理证实的儿童颈部囊状淋巴管瘤MSCT表现并与手术病理所见对照。结果:儿童颈部囊状淋巴管瘤MSCT的特点:①多囊性;②可出现"液-液平面"征象;③沿疏松结缔组织生长;④增强扫描囊壁不强化或轻度强化,囊内容物不强化;⑤肿瘤包绕血管、神经及脂肪;⑥MSCT可以水平横断面、冠状面、矢状面结合显示病灶。结论:MSCT检查对儿童颈部囊状淋巴管瘤的诊断具有重要价值,有利于手术方案的制订,在评价肿瘤侵犯方面优于超声和普通CT。更多还原

【Abstract】 Objective:To evaluate the value of multislice CT (MSCT) in the diagnosis of cystic lymphangioma of neck in children.Methods:The MSCT findings of 15 cases of cystic lymphangioma in the neck in children confirmed by operation and pathology were studied.All patients were performed MSCT before operation.Results:The major MSCT features of cystic lymphangioma included:multiple cysts (n=14);"Liquid-liquid level" sign (n=4);extension in loose connective tissue (n=14);mild or no enhancement in the cyst wall (14 cases),no enhancement in the content of the cyst;encasement of the blood vessel,nerve,and fatty tissue surrounding the lesion (n=13).MSCT can show the lesions from axial,coronal and sagittal planes.Conclusion:MSCT is very useful in diagnosing cystic lymphangioma of neck in children,and helpful to surgical treatment.It is superior to ultrasound and common CT in demonstrating the extension of the lesions.更多还原
