This is a 52 years old man who was operated for abdominal leiomyosarcoma. His liver metastases were treated with chemotherapy and the lesions were stable for over 9 months with no activity on a recent PET/CT. A CT scan showed a new lesion in segment 7.

Cryoablation was done using the 13G cryoprobe of a liquid nitrogen based system (IceCure, Israel).
