Primary liver cancer and liver metastases are among the most frequent malignancies worldwide, with an increasing number of new cases and deaths every year. Traditional surgery is only suitable for a limited proportion of patients and imaging-guided percutaneous thermal ablation has achieved optimistic results for management of hepatic malignancy. This synopsis outlines the first clinical practice guidelines for ultrasound-guided percutaneous microwave ablation therapy for hepatic malignancy, which was created by a joint task force of the Society of Chinese Interventional Ultrasound. The guidelines aim at standardizing the microwave ablation procedure and therapeutic efficacy assessment, as well as proposing the criteria for the treatment candidates.

The aim of this study was to evaluate the imaging features of testicular adrenal rest tumors (TARTs) on baseline ultrasound (BUS).The imaging features of 30 TART lesions pathologically or clinically confirmed in 15 patients who had undergone BUS were evaluated, and the sonographic characteristics of the lesions were analyzed.All 15 cases were bilateral and located near the testicular mediastinum. Approximately 56.7% (17/30) of the TART lesions exhibited homogeneous hypoechogenicity, 36.7% (11/30) of the lesions exhibited heterogeneous hypoechogenicity, and 6.6% (2/30) of the lesions exhibited heterogeneous isoechogenicity. In addition, 76.7% (23/30) of the lesions exhibited a rich blood supply, whereas 23.3% (7/30) of the lesions exhibited a scarce blood supply.The sonographic characteristics of the TARTs were bilateral growth, location adjacent to the testicular mediastinum, hypoechogenicity, and rich blood supply, which may play important roles in early clinical diagnosis.
