Case 1

Age: 22 years
Gender : Female
Clinical Detail :

  • Patient with osteosarcoma of right humerus with lung metastases.
  • PET CT showed FDG avid posterior chest wall based LUL lung lesion measuring 2.4 x 1.3 cm. Lung function well preserved.

Procedure :

  • Cryoablation done taking ablation zone of 28 x 29 mm with 2 x 10 minute cycles of freeze-thaw-freeze followed by 2.5 minutes of passive thaw.
  • Post-ablation check scan shows adequate ablation zone with surrounding atelectasis. No pneumothorax/hemothorax/chest wall hematoma seen.

Case 2

Age: 49 years
Gender : Male
Clinical Detail :

  • Patient recurrent symptomatic thymoma.
  • Previously treated with surgery.
  • CT scan showed recurrent retrosternal nodule measuring 1.2 x 0.9 cm, close to aortic arch.

Procedure :

  • Difficult access; induced pneumothorax and hydrodissection.
  • 2 x 3 minute freeze-thaw freeze cycles with 13 G cryoprobe.
  • Mild hydro-pneumothorax after procedure, inserted pleural drain which was removed next day. No injury to aortic arch.

Case 3

Age: 65 years
Gender : Female
Clinical Detail :

  • K/C/O adenocarcinoma of rectum post surgery + chemotherapy
  • Follow-up PET CT showed FDG avid nodule along right pelvic side wall

Procedures :

  • 2 x 5 minute freeze-thaw freeze cycles with 13 G cryoprobe
  • Adequate ablation margins with no post-procedure complications

Case 4

Age: 77 years
Gender : Male
Clinical Detail :

  • K/C/O left renal RCC post partial nephrectomy 12 years ago. Otherwise asymptomatic
  • On routine imaging, detected with enhancing nodule measuring 27 x 22 mm in resection bed close to left psoas

Procedure :

  • Treated with cryoablation using 2 x 8 minutes freeze-thaw-freeze cycles.
  • Adequate ablation margins with no post-procedure complications
