Infected Renal Cyst as a Complication of Dropped Gallstones during Laparoscopic Cholecystectomy

Figure 1

(a) Axial CT image of the abdomen obtained with IV contrast on patient’s admission to our institution, demonstrates two retained, dropped gallstones (black arrow) from the previous cholecystectomy, forming a fistulous tract from the posterior aspect of the second portion of the duodenum and an adjacent right renal cyst

(b) Axial CT image at a slightly lower level than in Figure 1(a) shows an infected right renal cyst with pockets of gas (yellow arrow). There is an additional retained gallstone in a laparoscopic cholecystectomy port (black arrow)
