Radiofrequency ablation (RFA) is a minimally invasive treatment modality used as an alternative to surgery in patients with benign thyroid nodules, recurrent thyroid cancers (RTCs), and primary thyroid microcarcinomas. The Korean Society of Thyroid Radiology (KSThR) initially developed recommendations for the optimal use of RFA for thyroid tumors in 2009 and revised them in 2012 and 2017. As new meaningful evidence has accumulated since 2017 and in response to a growing global interest in the use of RFA for treating malignant thyroid lesions, the task force committee members of the KSThR decided to update the guidelines on the use of RFA for the management of RTCs based on a comprehensive analysis of current literature and expert consensus.

Background/Aims: Portal vein thrombosis (PVT) frequently occurs in patients with inflammatory bowel disease (IBD), particularly when influenced by factors such as abdominal infections, IBD flare-ups, or surgical procedures. The implications of PVT range from immediate issues such as intestinal ischemia to long-term concerns including portal hypertension and its complications. However, there is a notable gap in comprehensive studies on PVT in IBD, especially with the increasing incidence of IBD in Asia. This research aimed to evaluate the clinical features and outcomes of PVT in patients with IBD at a leading hospital in South Korea. Methods: This retrospective analysis reviewed adult patients diagnosed with both IBD and PVT from 1989 to 2021 at a renowned South Korean medical center. The study focused on patient characteristics, specifics of PVT, administered treatments, and outcomes, all confirmed through enhanced CT scans. Results: A total of 78 patients met the study’s criteria. Notably, only 20.5% (16/78) were treated with oral anticoagulants; however, a vast majority (96.2%; 75/78) achieved complete radiographic resolution (CRR). When comparing patients receiving anticoagulants to those who did not, a significant preference for anticoagulant use was observed in cases where the main portal vein was affected, as opposed to just the left or right veins (p = 0.006). However, multivariable analysis indicated that neither anticoagulant use nor previous surgeries significantly impacted CRR. Conclusions Patients with IBD and PVT generally had favorable outcomes, regardless of anticoagulant use.

Sclerosing angiomatoid nodular transformation (SANT) of the spleen is extremely rare in pediatric patients. Here, we report the case of an 8-year-old boy with iron-deficiency anemia and a solitary splenic mass detected using US, CT, and MRI. The patient underwent partial splenectomy, and the final diagnosis was SANT. Herein, we discuss the radiological features of splenic SANT through a review of reported cases and the differential diagnosis of other primary splenic tumors.

Background: Patients with diabetic hindfoot ulcers typically harbor significant concerns regarding their prospects for healing or the potential for major amputation. Nonetheless, a scarcity of data addressing this prevalent and critical query exists. Thus, the aim of this study was to create an initial risk-scoring system to forecast the prognosis of individuals with diabetic hindfoot ulcers, leveraging assessments of ischemia and infection severity, which are recognized as the principal risk factors for amputation. Methods: Ischemia severity was categorized as iS0, iS1, or iS2 based on transcutaneous partial oxygen tension values, while infection severity was classified as iN0, iN1, or iN2 according to the results of tissue and bone biopsy cultures. Risk scores were determined by summing the scores for ischemia and infection severity, yielding a range of 0 to 4. Wound healing outcomes were graded as either healed with or without major amputation. Wound healing outcomes were assessed based on the assigned risk scores. Results: With ascending risk scores, the proportion of patients subjected to major amputation also increased (P value for trend < 0.001). Univariable logistic regression analysis revealed a significant positive correlation between escalating risk scores and major amputation incidence. Patients with a risk score of 4 exhibited a 41-fold higher likelihood of undergoing major amputation compared to those with a risk score of 0. Conclusion Risk scores can serve as a reliable predictor of the major amputation rate in patients with diabetic hindfoot ulcers.
