- Biopsy procedures (Fig.
9).
Nineteen lesions underwent CT-guided percutaneous biopsy: 14 lung lesions (mean diameter: 31.54 mm; range: 13-80 mm); 1 retroperitoneal lesion (78 mm diameter); 2 mediastinal lesions (70 and 90 mm diameter); 1 adrenal gland lesion (45 mm diameter); and one iliac muscle lesion (50 mm diameter).
One lung lesion (17 mm) was then treated with RFA.
All procedures were technically successful.
Mean procedural time was 42 min (range 12-97 min),
with a mean number of 8.15 CT scans (range: 4-19 scans).
No patient had major complications,
we observed 4 cases of pneumothorax but no case needed pleural drainage.
Biopsy on 16/19 lesions offered adequate tissue material for histopathological diagnosis: 10/16 adequate specimens showed neoplastic tissue (Fig.
10).
- Radiofrequency ablation procedures (Fig.
11).
Seventeen lesions were treated with radiofrequency ablation: 16 lung lesions (mean diameter: 20.45 mm; range: 6-48 mm) and one retroperitoneal lesion (37 mm diameter).
Mean procedural time was 58 min (range: 21-99 min),
with a mean number of 10.4 CT scans (range: 5-24 scans).
All RFA procedures were technically successful.
No patient had major complications,
we observed 5 cases of pneumothorax but no case needed pleural drainage (Fig.
12).
