This study indicates that the presence of intrinsic microcalcification is the only statistically reliable criterion on which to base increased suspicion for malignancy in thyroid nodules. Our results indicate the need for biopsy in determining further workup. All nodules that show the presence of intrinsic microcalcification should undergo biopsy, particularly if calcifications have a snowstorm appearance on sonography.

RFA and EtOH ablation show promise as alternatives to surgical treatment of recurrent WTC in patients with difficult reoperations. Further long-term follow-up studies are necessary to determine the precise role these therapies should play in the treatment of recurrent WTC.

• Prognostic indicators for success of CT-guided RFA of renal tumours are reported. • Tumour size ≥3.5 cm confers an increased risk for residual tumour. • Clear cell renal cell carcinoma subtype confers increased risk for residual tumour. • Tmax <70 °C within the ablation zone confers increased risk for residual tumour. • Exophytic tumours have a lower probability of residual disease.
