Osteoid osteoma is a benign bone tumor. Patients usually require surgical treatment for reliable pain relief. Difficulties with intraoperative localization of the tumor and anatomic locations that carry a high morbidity with en bloc resection complicate open surgery. Various methods have been developed to lessen the invasiveness of surgery including computed tomography-guided percutaneous radio...

Introduction: Aneurysmal bone cysts (ABC) are pseudocysts expansive lesions. The World Health Organization (WHO) categorizes primary ABCs as cystic neoplasms that contain fibrous septa separating numerous blood-filled spaces. Approximately 70% of ABC cases primary, while 30% secondary. Objective: present study aimed to carry out a concise systematic review the main clinical findings aneurysmal ...

Post-treatment or diagnostic whole-body radioiodine scintigraphy is widely used to assess the residual, recurrence, or metastases of differentiated thyroid carcinoma because of the high sensitivity and accuracy that this assessment provides. While bearing in mind all the diagnostic potential of this test, we have to consider its’ potential pitfalls, as well. Herein, we present 4 patients with d...

WITH the increasing incidence of renal cell carcinoma (RCC) in the United States and the increasing proportion of patients with tumors detected at an early stage (1–5), nephron-sparing approaches are becoming more popular. These alternatives to radical nephrectomy include partial nephrectomy, wedge resection, and, more recently, in situ thermal ablation. Five-year survival rates after partial n...

HYPOTHESIS Radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) can be performed by percutaneous or surgical approach. Tumor size is an important consideration while deciding the treatment approach. DESIGN Case series with prospective data collection. SETTING A tertiary referral center. PATIENTS A total of 228 patients who underwent RFA of small (</= 3 cm; n = 155) and medium ...

BACKGROUND Radiofrequency ablation has been established as a treatment method for malignancies and some particular cystic lesions, especially in adults. Experience with radiofrequency ablation in the treatment of hydatid cysts, especially in children, is limited. CASE REPORT Although echinococcosis is rare, especially in children, we describe a 7-year-old boy with lung and liver cystic echinoco...

A 70-year-old male patient with a history of metastatic lung cancer and type-2 diabetes mellitus presented with a complaint of right upper quadrant abdominal pain. Ultrasound showed a septated renal cyst in the right kidney. Abdominal computed tomography confirmed the presence of a septated cyst measuring 98 83mm in the right kidney with calcifications on the cyst borders (Figure 1). Indirect h...

Multiple interventional radiology techniques are available for percutaneous ablation of bone tumors: alcohol, laser, radiofrequency, microwave, ultrasound, and cryogenic ablation. Several indications have already been validated, including radiofrequency ablation of osteoid osteoma and bone metastases, with results superior to conventional treatment. More indications should be added over the com...

Radiofrequency ablation using a percutaneous catheter-based approach is widely used to treat supraventricular arrhythmias. Atrial fibrillation frequently arises from an abnormal focus at or near the junction of the pulmonary veins and the left atrium, thus leading to the feasibility of more focused ablation techniques directed at these structures. Catheter-based ablation, using both radiofreque...

Radiofrequency (RF) ablation has gained great popularity in the treatment of Hepatocellular Carcinoma (HCC) on cirrhosis and is replacing Percutaneous Ethanol Injection (PEI) in treating 3 cm or less HCC nodules. Its necrotic effect is more predictable than that of PEI and therefore RF can achieve a longer local tumor progression control and survival. In the last four years many data on its eff...
