Stereotactic ablation of undetectable breast cancer metastasis
Stereotactic ablation of undetectable breast cancer metastasis
1:41
CT-MR fused, stereotactic, CT-guided microwave ablation of an initially invisible breast cancer metastasis in liver segment VI. Due to various patient comorbities, the microinvasive ablation procedure with CAS-One was chosen.

1. Pre-operative MRI showing lesion
2. 50/50 fusion of MRI and CT view
3. CT scan not showing the lesion
4. Needle control
5. Ablation control CT scan
6. Postoperative ablation control
Name: PD Dr. med. Anja Lachenmayer & Dr. med. Carlo Tappero
Institution: Inselspital Bern
Patient age and sex: 79 years, female
Initial condition:
- 2012: Mammary carcinoma
- 2018: Recurrent Mammary carcinoma
- 2018: Sigma carcinoma
- 2018: Metastatic disease from colon carcinoma
- Colorectal and breast cancer with suspicious lesion on the MRI venous phase
- Age and various comorbitities prevented the patient from undergoing open surgery
- No chemotherapy possible either
- In 2018 a PET-CT scan was performed, which was positive for the liver lesion
- The lesion was initially invisible on the CT scan, therefore treatment with CAS-One IR to be able to fuse imaging modalities (CT/MRI)
Treatment:
- Minimal invasive percutaneous stereotactic CT-guided biopsy and microwave ablation of a single liver metastasis in segment VI
- By fusing CT and MRI imaging modalities with CAS-One the lesion could be successfully biopsied and ablated
Conclusion:
- Patient recovered quickly after intervention
- First follow-up scan confirmed complete ablation of tumor
