Radiofrequency Ablation
Is the process by which discrete quantities of energy in the form of radiofrequency are deposited in specific tissues in an attempt to cause coagulative necrosis in a predetermined area.

Diagnosis:
THE PATIENT TOOK A BREATH which moved the kidneys superior and created an artifact that appears as though there is a mass above the left kidney. It is very important to keep a wide angle when looking at an area of suspected pathology. (It is tempting to narrow ones field to the area of interest.)
arterial transposition, VSDs, ASDs, atrioventricular septal defect, anomalous pulmonary venous return, tricuspid atresia, and pulmonary arterial hypoplasia or atresia. • 50% of people with Primary Ciliary Dyskinesia (PCD) have Kartegener's syndrome: situs inversus, chronic sinusitis and otitis, and airways disease leading to bronchiectasis • 25% of people with situs inversus have PCD • If none of the above associated abnormalities are present then it is usually asymtomatic
• Currently radiofrequency ablation is used to treat hepatocellular carcinoma, colon metastases to the liver, renal cell carcinoma, chordomas, osteoid osteomas, fibroids, cutaneous metastases, and other tumors are under investigation. It is currently FDA cleared for the “treatment of soft tissue masses”

Indication
• Radiofrequency ablation was first used in the treatment of unresectable hepatocellular carcinoma. This patient population provided a means to show that radiofrequency is safe, useful, technically straightforward and inexpensive.
• Size and proximity to adjacent organs limits the use of radiofrequency ablation.

Patient History
• The 66 year old male patient was diagnosed with colon cancer metastatic to the liver and received one treatment of radiofrequency ablation with recurrence prior to being referred to the interventional radiology team at BIDMC.
