case_images: Abdominal magnetic resonance imaging of a 5-year-old girl with a percutaneous transhepatic biliary drainage after liver transplantation. Coronal T2-weighted image shows a hypointense structure (arrows) measuring 1.6 x 1.6 x 3.5 cm at the distal end of the biliary drainage (arrowheads) in the bowel lumen in the right lower quadrant

case_images: In May 2024, after fluoroscopic identification of the radiolucent stone surrounded by contrast agent in the bowel lumen (Fig. 3 and Supplementary Material 1), percutaneous transhepatic lithotripsy was performed via the percutaneous transhepatic biliary drainage with an 8-mm and then a 12-mm balloon (Mustang  Balloon Dilatation Catheter, Boston Scientific, Marlborough, MA).
case_images: Abdominal ultrasound of a 5-year-old girl with a percutaneous transhepatic biliary drainage with associated stone formation. Abdominal ultrasound was performed to correlate the magnetic resonance imaging finding (see Fig. 1). a Longitudinal and (b) transverse ultrasound shows the stone at the biliary drainage tip with hyperechoic stone outline (arrows) and posterior acoustic shadowing

case_images: Correlation with ultrasound (Affiniti 70 Ultrasound, Philips Healthcare, Amsterdam, Netherlands) showed oval acoustic shadowing at the tip of the drainage (Fig. 2) and intermittent short segment small bowel intussusception around the drainage. The stone appeared to be somewhat elastic and flexible expanding during balloon dilatation (Fig. 4 and Supplementary Material 2).
case_images: Fluoroscopy of a 5-year-old girl with a percutaneous transhepatic biliary drainage-associated stone formation. Fluoroscopy shows the radiolucent stone (arrows) at the drainage tip surrounded by contrast agent. A video is included as Supplementary Material 1

case_images: Fluoroscopy of a 5-year-old girl with a percutaneous transhepatic biliary drainage-associated stone formation. Displaced radiolucent stone fragments (arrows) are visible in the small bowel lumen in the lower right quadrant after successful lithotripsy. A video is included as Supplementary Material 3
