ABSTRACT
Polypoid ganglioneuroma in the descending colon is rare and typically confined to the mucosa and submucosa. This report presents a pediatric case initially detected by ultrasonography as descending colon intussusception with significant bowel wall thickening. The tumoriform pathological lead point was identified during ultrasound-guided hydrostatic reduction, which was ultimately confirmed by postoperative pathology as an atypical polypoid ganglioneuroma infiltrating the muscular layer. We discuss the clinical value of ultrasonography and the risks associated with deep infiltration. Furthermore, we summarize the sonographic features of the lesion, which manifest as a broad-based, hypovascular solid mass accompanied by bowel wall thickening.
