An initially diagnosed RCC was treated with radical nephrectomy of the left kidney in 1991, along with a partial nephrectomy of the right kidney in 2007. Pulmonary mets were diagnosed in 2017, treated with chemo, and the right kidney was treated with multiple MWA. A metastatic lesion of the right adrenal gland was detected in 2021 and treated with radiotherapy, however, in 2023 it showed progression and it was decided that the patient was to be treated with MWA and CAS-One IR due to the challenging position of the target directly adjacent to the inferior vena cava. Two overlapping ablation zones were planned and executed transhepatically, along with track ablation to prevent tumor seeding. Post-procedure, the lesion showed a reduction and there were no periprocedural complications. The patient awaits longer term follow up but is doing well.
