Fig. 2From: Multidetector CT cystography for imaging colovesical fistulas and iatrogenic bladder leaksAn 80-year-old woman undergoing routine body CT for long-standing, unexplained fever. Air was present in the urinary bladder, with Foley catheter balloon in place (a). MDCT cystography (axial, sagittal reformatted and oblique coronal images in b, c, and d respectively) obtained adequate bladder distension with instillation of 300 ml diluted contrast medium, and visualization (arrowheads) of a subtle, initially unsuspected colovesical fistula due to colonic diverticular diseaseBack to article page
