On the 7th postoperative day after laparoscopic cholecystectomy, urgent MR including fat-saturated T2-weighted (a) and MRCP (b) showed sizeable biloma (*) extending ventrally from the gallbladder fossa, some peritoneal fluid and mildly dilated CBD containing multiple millimetric filling defects consistent with stones (thin arrows in b). Gadoxetic acid-enhanced MRCP confirmed residual choledocholithiasis (thin arrows in c) and allowed detecting a small biliary leak (arrow in d) from the cystic duct remnant (arrowheads), causing opacification of the biloma (*). Endoscopic treatment included sphincterotomy and placement of a self-expanding metal stent
