The sonographic morphology of urachal remnants is not well known and findings tend to be misinterpreted. We present urachal remnants in 16 asymptomatic children (1 week-16 years). In the prevesical part two different types of urachal remnants were found: the tubular type with a small outer muscle wall and the fusiform type with a muscle wall thickness up to 12 mm. Further subvariants are presented. Differential diagnosis of the fusiform type includes urachal cyst and tumorous muscle thickening.
脐尿管残余物的超声形态学鲜为人知，其检查结果往往被误解。我们展示了16例无症状儿童（年龄从1周大到16岁）的脐尿管残余物情况。在膀胱前部分发现了两种不同类型的脐尿管残余物：一种是管状类型，其外部肌壁较薄；另一种是梭形类型，其肌壁厚度可达12毫米。还展示了进一步的亚型。梭形类型的鉴别诊断包括脐尿管囊肿和肿瘤性肌增厚。
