Abdominal ultrasound (US) showed no intestinal intussusception, but a severely distended gallbladder (7.5 cm in diameter) containing biliary sludge (Figure 1).
MR cholangiography: a coronal maximum intensity projection (MIP) shows a distended gallbladder with no sign of the cystic duct (arrow).

MR cholangiography (Figure 2) confirmed the gallbladder distension, while the cystic duct was not detectable; the rest of the intra- and extrahepatic biliary tree and the hepatic parenchyma were normal.
