Sagittal reformatted image from CT scan shows cord-like midline structure (curved arrow) extending from the bladder toward the umbilicus representing the median umbilical ligament. The calcifications (straight arrow) are located at the insertion of the ligament onto the urinary bladder. Note that there is no outpouching of the bladder wall at the insertion of the ligament to suggest the formation of a urachal diverticulum.
