CAScination Cases - Blog

CAScination Cases presents cases performed with CAScination's stereotactic navigation systems. They support diagnosis, treatment and palliative therapy of cancer. CAS-One navigation systems enable the precise localization, puncture and ablation of tumors in liver, kidney and lung. All CAScination Cases are designed in user-friendly way: After the presentation of the treating experts and their institution, age, sex and initial condition of the patient are described. The following section outlines the treatment, followed by a final evaluation. Scans and images illustrate the different stages of planning and intervention and give a more vivid impression of the challenges and benefits of the chosen treatment.

    Stereotactic ablation enables microinvasive treatment of undetectable breast cancer metastasis

    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)
    Video CT - MRI Fusion

    • 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


    • Patient recovered quickly after intervention
    • First follow-up scan confirmed complete ablation of tumor
