摘要
目的探讨先天性舌根囊肿的影像学表现。方法回顾性分析34例先天性舌根囊肿患者的CT、MRI及超声资料,并与喉镜及病理结果对照。结果 34例患者均经病理确诊。MR检查22例,CT检查13例,超声检查13例,表现为舌根部、会厌舌面、舌根舌体交界处或会厌间隙的囊性病变,6例邻近咽腔受压变窄。MRI呈长T1长T2信号,CT表现为囊状低密度,增强扫描无强化;超声表现为舌根部囊状液性暗区,边界清,后伴声影。其中12例行喉镜检查,显示舌根部囊性肿物压迫会厌软骨致抬起受限,会厌软骨软化,吸气相部分阻塞声门,致通气不畅。结论舌根囊肿影像学表现具有一定特征性,对于诊断、鉴别诊断和术前精确定位具有重要价值。超声检查是首选的方法,MRI是最佳影像学方法。
Objective To discuss the imaging appearance of congenital lingual root cyst.Methods 34 cases of congenital lingual root cyst were studied retrospectively.The imaging results were compared with pathology and laryngoscope.Results All 34 cases were correctly diagnosed according to the typical imaging appearance,and were confirmed by pathology.Twenty-two cases underwent MRI examination,thirteen underwent CT and thirteen with US examination,showing a cystic lesion at the root of tongue,lingual surface of epiglottis,junctional zone of root and body of the tongue,or the epiglottis clearance,six cases with narrowing of the cavum pharyngis.The lesions were shown homogeneous hypo-intence on T 1-weighted image and hyper-intence on T 2-weighted image,and homogeneous hypo-density on CT image.Only one case demonstrated slight enhancement sign of local cystic wall on contrast enhancement MRI.On ultrasonographic,the lesions were shown as cystic fluid dark space with posterior shadowing.The laryngoscope displayed the epiglottis was oppressed and softened by lingual root cyst,which caused poor ventilation.Conclusion Imaging appearance can display the features,positions,relationship with surrounding tissue of congenital lingual root cyst.Ultrasonography is the feasible and first choice,while MRI should be the best methods.
