There is excellent hepatic function with good blood clearance. There is a large photopenic defect encompassing the central portion and right lobe of the liver seen on the initial image and is carried through to the 60 minute image. There is visualization of tracer in bowel at 12 minutes. There is a focal collection of activity at the inferior hepatic margin that is consistent with tracer in the gallbladder. Images at 4 hours show a focal collection of tracer in the central portion of the liver that corresponds to the region of photopenia identified in the dynamic images from the first 60 minutes.
Findings are compatible with a choledochal cyst.
