Extraabdominal desmoid (EAD) tumors pose a therapeutic challenge because they often recur locally and behave aggressively. Accepted management options include surgery, radiation, chemotherapy, observation. The objective of this study was to assess the safety efficacy percutaneous cryoablation for treatment EAD tumors.A retrospective search our database performed identify patients with treated between June 15, 2004, 2014. During 10-year time period, we 18 26 discrete during 31 sessions. After...

To evaluate the clinical and radiographic predictors of need for partial or circumferential resection inferior vena cava (IVC) requiring complex vascular reconstruction during venous tumour thrombectomy renal cell carcinoma (RCC).Data were collected on 172 patients with RCC IVC (levels I-IV) thrombus who underwent radical nephrectomy at Mayo Clinic between 2000 2010. Preoperative imaging was re-reviewed by one two radiologists blinded to details patient's surgical procedure. Univariable...

Background Acute allergic-like and physiologic reactions occur following administration of gadolinium-based contrast agents (GBCAs) for MRI examinations. Because these are uncommon, it is challenging to compare reaction rates between GBCAs determine risk factors. Purpose To the four gadodiamide, gadobutrol, gadobenate dimeglumine, gadoterate meglumine, potential factors reactions. Materials Methods This retrospective study identified all intravenous GBCA injections examinations performed at...

Background It is unclear whether steroid premedication an effective means of preventing repeat allergic-like reactions in high-risk patients with a previous reaction to iodinated contrast material (ICM). Purpose To compare the effectiveness ICM substitution (ie, using iohexol patient iopromide reaction) 12- and 2-hour for acute patients. Materials Methods This retrospective study identified all having adult pediatric who underwent contrast-enhanced CT examination at institution from June 1,...

Thyroid nodule treatment has significantly evolved over recent years with attempts to individualize on the basis of cause and patient performance status. The risks complications associated surgery radioactive iodine have promoted interest in additional therapies such as radiofrequency ablation (RFA). RFA creates an electrical current through a target tissue (thyroid nodule) resultant heating causing coagulative necrosis. National international groups are beginning recognize role viable...

Imaging-guided percutaneous core needle biopsy (PCNB) is currently the most common technique for investigation of potentially malignant bone lesions. It allows precise placement and better visual guidance, leading to improved diagnostic accuracy. Needle tract seeding (NTS) a rare complication biopsies in general, its true incidence remains unknown. This study aimed assess risk NTS patients with thyroid cancer who underwent biopsy. For our cohort, we extracted data from electronic medical...

The purpose of this study was to evaluate the early outcomes percutaneous microwave ablation (MWA) for clinical stage T1 (cT1) renal masses when performed within a high-volume practice with critical emphasis on procedural safety.A retrospective review registry identified 26 patients total 27 cT1 treated MWA between 2011 and 2017. Mean patient age 63.8 years 16 (61.5%) were male. mass size ± SD 2.3 0.8 cm (range, 1.1-4.7 cm). main outcome parameters investigated technical success, local tumor...

Abstract Background Autonomously functioning thyroid nodules (AFTNs) constitute 5% to 7% of and represent the second most common cause hyperthyroidism following Graves’ disease. Currently, radioactive iodine (RAI) surgery are standard treatment options, both incur a risk postprocedural hypothyroidism other radiation-related complications. Methods This work aimed at assessing efficacy radiofrequency ablation (RFA) as an alternative option for resolving nodule volume rate reduction (VRR) its...

Abstract Context After a thorough evaluation most thyroid nodules are deemed of no clinical consequence and can be observed. However, when they compressive, toxic, or involved by papillary carcinoma surgery radioactive iodine (RAI) (if toxic) the treatments choice. Both interventions lead to hypothyroidism other adverse outcomes (eg, scar, dysphonia, logistical limitation with RAI). Active surveillance might used for microcarcinoma (PTMC) initially, but anxiety leads many cases later....
