(a) Axial image of CT abdomen with IV contrast obtained 4 days after admission to our institution shows the fistula tract at the posterior aspect of the second portion of the duodenum with two adjacent calculi (black arrow). Also note retained contrast in the left kidney from the previous CT, indicating associated pyelonephritis

(b) Axial CT image at a slightly lower level than in Figure 3(a) shows right perinephric inflammation associated with the infected renal cyst with gas (red arrow). Also note bilateral retained contrast in the kidneys from the previous CT, indicating pyelonephritis
