RESUMO
Percutaneous image-guided ablation with the use of radiofrequency has recently received much attention as a minimally invasive technique for the treatment of solid malignancies. Renal cell carcinomas (RCCs) were among the first extrahepatic tumours to be targeted with radiofrequency ablation (RFA). The aim of this study is to present the efficacy of RFA in RCC and the factors that have an impact on the attained necrosis with regards to the histological findings.

We report the case of an immunocompetent, 39 year old male who presented with diplopia and diffuse headache. The CT scan demonstrated the presence of a sizeable mass that took over the nasal cavity, the right maxillary sinus, the sphenoid and ethmoid sinus, extending to the sellar and suprasellar region, and eroding the adjacent bones. The patient also underwent MRI and endoscopic sinus surgery. Biopsy of the suspected tissue for pathology and culture demonstrated Aspergillus fumigatus.

We report two cases of successful percutaneous therapy of epithelial splenic cysts. A 19-year-old woman and a 48-year-old man underwent drainage of their epithelial cysts with subsequent instillation of alcohol into the cavities under computed tomographic guidance.
