The hepatic tumour discovered during follow-up for a previous bladder cancer submitted to endoscopic surgery three years before measured 22 mm in diameter and was located in the VIII Couinaud's segment of the liver in association with three smaller hypodense liver lesions with a focal dilatation of peripheral biliary tree (Figure 1).

The fluorescing tumour has been clearly identified and defined on the liver surface, as shown in Figure 2.

We have also identified that a large area of fluorescent parenchyma that gets from the peripheral of the lesion up to the portal pedicle such as the neoplasia would interest the right biliary tree in the form of neoplastic lymphangitis (Figure 3).

 In this case, fluorescent imaging has revealed a fluorescing ring around the hepatic metastasis (Figure 4).
