Zhigang Guo, Zhijia Wang, Kai Li, Chao Du, Xingli Zhao, Min Cheng, Yu Tian
Objectives: Patients with trigeminal neuralgia who are refractory to medical therapy may choose to undergo Gasserian ganglion percutaneous radiofrequency thermocoagulation. However, in cases where the foramen ovale is difficult to access due to various anatomical anomalies, the typical estimation of the facial entry point is suboptimal. Methods: Three-dimensional computed tomography reconstruction imaging performed before surgery revealed anatomical variations in each of the four adult patient cases that made it more difficult to successfully access the foramen ovale (FO) for percutaneous radiofrequency thermocoagulation...

Patients with hepatocellular carcinoma who are on liver transplant waiting list usually require local treatment to limit any risk of tumour growth. Historically percutaneous radiofrequency ablation or transarterial chemoembolization represented the major therapeutic alternatives. Depending on the size, or the topography of the lesion these two techniques may not be feasible. Radiation therapy under stereotactic conditions has recently emerged in the management of localized hepatocellular carcinoma as an alternative to the focused therapies performed to date...

The combination of Wolff-Parkinson-White (WPW) syndrome and rheumatic mitral stenosis (MS) is rare in clinical practice. The management of this condition primarily depends on the clinical picture. We describe a 26-year-old male patient with no significant previous medical history and who came for a routine medical assessment before entrance to a police academy service. He was found to have rheumatic MS and WPW.

Discovery of small solid renal masses via echography, CT-scan or MRI is common in current medical practice, with more than 70 % found incidentally. Although they include benign lesions, most are renal cell carcinomas. A radiological assessment, associated if necessary with a percutaneous renal biopsy, leads to their diagnosis in the vast majority of cases. Minimally invasive partial nephrectomy has become the standard surgical technique in specialized centers. Ablative therapies (radiofrequency and cryotherapy) and active surveillance are other possible therapeutic approaches...

PURPOSE: An increasing interest in percutaneous ablation of renal tumors has been caused by the increasing incidence of SRMs, the trend toward minimally invasive nephron-sparing treatments and the rapid development of local ablative technologies. In the era of shared decision making, patient preference for non-invasive treatments also leads to an increasing demand for image-guided ablation. Although some guidelines still reserve ablation for poor surgical candidates, indications may soon expand as evidence for the use of the two most validated local ablative techniques, cryoablation (CA) and radiofrequency ablation (RFA), is accumulating...

We present a 13-month-old boy who had a successful Computed Tomography (CT) guided percutaneous radiofrequency ablation (RFA) treatment for the osteoid osteoma (OO) on proximal part of the tibial diaphysis. The complaints of the patient were being restless due to pain and refusing to bear any weight on his left leg for 6 months. An asymmetrical cortical thickening and a focal sclerosis was detected on medial proximal diaphysis of the left tibia on radiographs and axial T2-weighted STIR-MR image showed bone marrow and soft-tissue edema with low-signal-intensity nidus due to central calcification with a high-signal-intensified unmineralized periphery...

Because of mostly asymptomatic cyst growth and often-neglected nonspecific low-grade symptoms, many cases of cystic echinococcosis (CE) caused by Echinococcus granulosus in the pediatric population are diagnosed at school age, in an advanced and even complicated stage. In 2003, after 5 months of intermittent dull upper-right abdominal pain and nausea, a 13-year-old boy was diagnosed with massive liver CE, with ∼20 round-shaped double-walled medium-sized infective cysts, which permeated the whole liver. Because of their wide distribution across the liver tissue and the risky superficial position of some cysts, liver transplantation emerged as the optimal therapeutic option...

The effective treatment for hepatocellular carcinoma (HCC) with American Joint Committee on Cancer stage IIIB remains controversial and challenging because of the high recurrence rate after resection and low survival rate. The median survival of those with macroscopic portal vein tumor thrombus (PVTT) is short. We reported such a case which received liver transplantation (LT) after successful consecutive downstaging therapies. A 40-year-old man with alcohol related liver cirrhosis and repeated esophageal varices bleeding had HCC with tumor thrombi in right main portal vein and the second portal branch of segment VI (stage IIIB)...

For hepatocellular carcinomas, radiofrequency ablation is extensively used to alleviate primary and metastatic hepatic tumours. Common complications of this procedure include bleeding, infection, and hollow organ perforation. We present the case of a patient with hepatoma who underwent radiofrequency ablation. He had intractable cough with yellowish sputum, particularly while lying down, three weeks after treatment. Chest computed tomography demonstrated a right middle lobe consolidation with pleural effusion and right subphrenic fluid collection...

RATIONALE: Programmed cell death-1 (PD-1) or programmed death-ligand 1 (PD-L1) immune checkpoint inhibitors have demonstrated impressive efficacy in patients with nonsmall cell lung cancer (NSCLC). Radiofrequency ablation (RFA) is an alternative locoregional therapy for patients with inoperable NSCLC. We report the role of RFA in a patient with metastasis from advanced stage NSCLC that was managed with checkpoint inhibitors. Therefore, this combination of RFA with subsequent immunotherapy can control NSCLC better than RFA or immunotherapy on their own...

Osteoid osteoma is a benign bone-forming tumor with hallmark of tumor cells directly forming mature bone. Osteoid osteoma accounts for around 5% of all bone tumors and 11% of benign bone tumors with a male predilection. It occurs predominantly in long bones of the appendicular skeleton. According to Musculoskeletal Tumor Society staging system for benign tumors, osteoid osteoma is a stage-2 lesion. It is classified based on location as cortical, cancellous, or subperiosteal. Nocturnal pain is the most common symptom that usually responds to salicyclates and non-steroidal anti-inflammatory medications...

Safe and effective percutaneous CT-guided radiofrequency ablation of spinal osteoid osteomas can be performed using a targeted navigational bipolar electrode system. Articulating bipolar electrodes with built-in thermocouples along an electrode shaft and variable generator wattage settings allow optimal nidus access, particularly in challenging locations; provide precise real-time monitoring of ablation zone volume and geometry; and minimize the risk of undesired thermal injury.
