目的总结分析儿童甲状舌管囊肿(TDC)合并感染的超声图像特点,提高该病的诊断准确率。方法经病理组织检查证实的67例TDC合并感染的儿童患者,其中男性44例,女性23例;年龄2~13岁,中位年龄5.6岁。回顾性分析其超声图像,分别从病灶部位、大小、形态、边界、囊壁厚度、内部回声、后壁回声增强及彩色多普勒血流成像(CDFI)等方面总结该病图像特点。结果儿童TDC合并感染主要超声图像特点为厚壁或囊壁显示模糊多见,内部回声以混浊、伴粗光点、絮状回声及不均匀混合回声为主,多无后壁回声增强,CDFI于病灶囊壁间、病灶内部及周围组织可检出血流信号。结论儿童TDC合并感染有相对特异的超声图像特点,超声对该病可早期作出诊断及鉴别诊断,为临床医生提供有效可靠的诊疗依据。
Objective To summarize and analyze the characteristics of ultrasound images of children with choledochal cyst (TDC) infection and to improve the diagnostic accuracy of the disease. Methods Totally 67 children with TDC complicated infection were confirmed by pathological examination, including 44 males and 23 females. The median age was 2 to 13 years old and 5.6 years old. The ultrasound images were retrospectively analyzed. The features of the lesion were summarized from lesion location, size, shape, boundary, wall thickness, internal echo, posterior wall echo enhancement and color Doppler flow imaging (CDFI). Results The main features of TDC in children with TDC were as follows: the thick wall or the cyst wall were fuzzy, the internal echo was cloudy, with coarse spots, flock echo and heterogeneous mixed echo, Between the lesion wall, lesions and the surrounding tissue can be detected blood flow signal. Conclusions Children with TDC co-infection have relatively specific features of ultrasound images. Ultrasonography can make early diagnosis and differential diagnosis of the disease, providing clinicians with an effective and reliable diagnosis and treatment basis.
