title: Urachal remnants in asymptomatic children: sonographic morphology.
abstract: 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.
