School ager with sickle cell disease and abdominal pain

US of gangrenous cholecystitis
Sagittal (left) and transverse (right) US of the gallbladder show the gallbladder to be filled with sludge and debris. The gallbladder wall is thickened and in one area was felt to be discontinuous. There were multiple gall stones present in the common bile duct (not pictured).

The diagnosis was gangrenous cholecystitis due to choledocholithiasis in a patient with sickle cell disease.
