Transverse ultrasound of the bladder (above left) shows an oval lesion in the center of the bladder that has a thick wall and a hypoechoic center. AP image early in the filling phase of a voiding cystourethrogram exam (above right) shows an oval lucent filling defect representing a lesion in the center of the bladder. AP image from later in the filling phase (below left) shows the filling defect / lesion is within the bladder. Lateral image from the voiding phase (below right) shows the lesion has everted out of the bladder. Left sided vesicoureteral reflux was also present.
