Little is known about the possibility that ruptured appendicitis may produce a false sonographic appearance of intussusception. We present here a case of a periappendiceal phlegmon mimicking ileocolic intussusception on ultrasound in a 3.5-year-old girl and provide a surgico-anatomic explanation on the basis of the intraoperative findings for the false sonographic image. CT imaging was used to make the diagnosis. Intraoperatively, it was revealed that the cecum and sigmoid, which were adherent to each other with pseudomembranes, formed an intestinal mass around the appendix. Accordingly, the appendicolith at the center of the phlegmon was responsible for the central echogenicity, and the surrounding cecum and sigmoid for the external hypoechoic and hyperechoic rings of the target-sign appearing mass on the preoperative ultrasound. Such an understanding of the etiology of the false sonographic image may help to increase awareness and avoid misdiagnosis.
Axillary lymph node (ALN) staging is crucial for the management of invasive breast cancer (BC). Although various radiological investigations are available, ultrasound (US) is the preferred tool for evaluating ALNs. Despite its immediacy, widespread use, and good predictive value, US is limited by intra- and inter-operator variability.
To evaluate the accuracy of the O-RADS system in differentiating between benign and malignant adnexal masses, as assessed by inexperienced gynecologists. Ten gynecologic residents attended a 20 h training course on the O-RADS system conducted by experienced examiners. Following the training, the residents performed ultrasound examinations on patients admitted with adnexal masses under supervision, recording the data in a database that included videos and still images.

* Analyzed data from 6,614 fetuses revealed a detection rate of 64.1% for CHD and 85.7% for major CHD, with various statistical values indicating strong specificity and predictive accuracy.
* Findings highlight that scanning the fetus with the spine in a posterior position significantly increases detection rates, while low maternal body mass index (BMI) may contribute to a higher likelihood of false negatives.
The macrofollicular subtype of papillary thyroid cancer (MFS-PTC) is a rare subtype often leading to a challenging diagnosis. To evaluate the ultrasonographic (US) features and clinical implication of MFS-PTC. Records of 14 patients histologically diagnosed with MFS-PTC at our institution over a period of 16 years were retrospectively reviewed.

Objective: This study aims to create a new screening for preterm birth < 34 weeks after gestation with a cervical length (CL) ≤ 30 mm, based on clinical, demographic, and sonographic characteristics.
Methods: This is a analysis of a randomized clinical trial (RCT), which included pregnancies, in middle-gestation, screened with transvaginal ultrasound. After observing inclusion criteria, the patient was invited to compare pessary plus progesterone (PP) versus progesterone only (P) (1:1).
