Microwave ablation of an unfavorably located lesion in segment I of the liver with a distance of only 4 mm to the vena cava inferior and a distance of 3 mm to the left portal vein. Follow-up Gadoxetate enhanced MRI showed expected postinterventional change with diminished intracellular uptake of the contrast agent without any trace of residual tumor.

Institution: Inselspital Bern
Patient age and sex: 52 years, female
Initial condition:
Due to the unfavorable location in the caudate lobe ( Fig. 1 ) with a distance of only 4 mm to the inferior cava vein and a distance of 3 mm to the left portal vein surgery would be invasive and extensive. As the lesion was located just between the left portal vein and the vena cava inferior, it would have been very difficult even for an experienced interventionalist to position the ablation probe precisely within the lesion while not risking to in jure the vessels and otherwise to ensure a full therapeutic coverage of the lesion. Therefore the navigation system CAS-One was used to perform the procedure.
