Over a period of 2 years, MRI-guided cryoablations were performed in 10 patients presenting with complex cases of primary or secondary malignant liver tumors. Tumors (average diameter 2cm) were either not visible in CT/ultrasound, difficult to approach, or not treatable with radiofrequency ablation. Primary endpoint of this retrospective study was local recurrence in the ablated area. Over the follow-up period ranging from 8 to 44 months: local recurrence occurred in two patients; three patients died and one patient was lost to follow-up without evidence of local recurrence; other patients remained disease-free at the end of the study.
