Robert's uterus is a rare Müllerian duct anomaly (MDA) characterized by complete asymmetric septum dividing uterine cavity into two non-communicating parts. This study offers insights into diagnosing and management of this condition in a young patient, and a systematic literature review. The review included 19 studies from 2013 to 2023. 11.4% of women reported a history of miscarriage and 5.7% primary infertility. Dysmenorrhea was the most frequent symptom (54.3%), and 14.3% of patients had a coexisting endometriosis...

Multi-systemic metastasis in patients with Peutz-Jeghers syndrome (PJS) is very rare, and there are nearly no relevant imaging reports, especially in contrast-enhanced ultrasound (CEUS). We present here a 40-year-old male patient who underwent several partial small bowel resections and endoscopic polypectomy for intestinal polyps. After reviewing the patient's clinical diagnosis and treatment process, CEUS with sulfur hexafluoride microbubbles (SonoVue, Bracco, Milan, Italy) in the liver and gastrointestinal tract was performed...

METHODS: This retrospective study of breast cancer patients who underwent neoadjuvant therapy (NAC) and ultrasound scanning between November 2020 and July 2023. First, a radiomics model was established based on ultrasound images. Subsequently, multivariate LR (logistic regression) analysis incorporating both radiomic scores and clinical factors was performed to construct a nomogram...

OBJECTIVE: Our aim was to investigate the significance of cerebro-placento-uterine ratio CPUR, a new Doppler index, and fetal cardiac parameters (Mod MPI, EFT) in early-onset preeclampsia (EOPE) and to examine whether these parameters are related to perinatal outcome. STUDY DESIGN: Forty participants diagnosed with EOPE (preeclampsia cases diagnosed before 34 weeks of gestation) and 40 healthy pregnant women were included in this study. Demographic data were recorded...

Rhabdomyosarcoma (RMS) is the most common malignant soft tissue tumor in children, and botryoid rhabdomyosarcoma (BRMS) represents a subtype of RMS. BRMS primarily occurs in infants, young children, and adolescent females, with a predilection for mucosa-lined hollow organs such as the bladder, vagina, bile duct, and so on. Its occurrence in the biliary tract is extremely rare. Due to the high malignancy and rapid metastasis of biliary botryoid rhabdomyosarcoma, early diagnosis and treatment are crucial for improving prognosis...

PURPOSE: To investigate power Doppler (PD) activity and tendon structure (between the injured and contralateral limb) in patients with unilateral patellar tendinopathy (PT) using ultrasonography (US). Secondly, the aim was to determine the intra-rater reliability of the PD activity and tendon structure. METHODS: This study analyzed US baseline data from 57 male participants with symptomatic unilateral PT who had been enrolled in one of two randomized clinical trials...

PURPOSE: While scanning women for breast US, is possible to observe changes in the appearance of the pleural line or in the most superficial portion of the lung. The objective of this single-center, prospective study was to determine the prevalence of a variety of pleural and pulmonary US findings during routine breast US. METHODS: In this study, there were 200 women undergoing standard breast US examination. The presence of pleural and pulmonary abnormalities in these cases was recorded...

PURPOSE: This study was designed to investigate the application value of the atrial septum excursion index (ASEI) in fetuses with isolated restrictive foramen ovale (RFO) or redundant foramen ovale flap (RFOF) and the outcomes of these fetuses. METHODS: This was a retrospective study. Healthy pregnant women who were examined by antenatal fetal echocardiography from January 1, 2019 to December 31, 2021, at Sir Run Run Shaw Hospital were enrolled. One hundred seventy-seven (177) fetuses were categorized into three groups by diagnosis: (1) RFOF (n = 33), (2) RFO (n = 21), and (3) normal (n = 123)...

PURPOSE: To analyze ultrasound features of cervical thoracic duct for patients with constrictive pericarditis and chylothorax. METHODS: Patients were retrospectively assessed. The patients were divided into a non-pleural effusion (PE) group (n = 54), a chylothorax group (n = 23), and non-chylothorax group (n = 28). Conventional ultrasound was used to obtain the maximum inner diameter and collapse of the inferior vena cava, the inner diameter of left cervical thoracic duct, and the frequency of opening of the valve at the end of the left thoracic duct...

Magnetic resonance imaging (MRI) can provide additional information in cases of cesarean scar pregnancy beyond the first trimester. MRI and 3D reconstructions can demonstrate the relationships between the uterus, cervix, bladder, and placenta, improving the spatial perspective of the pelvic anatomy in cases requiring surgical management. MRI and 3D reconstructions can also provide more comprehensive images for parental counseling, virtual and face-to-face multidisciplinary team discussion, and medical record storage...

OBJECTIVE: To examine third-trimester sonographic imaging of the fetal pancreas in uncomplicated pregnancies and its association with pregnancy outcomes. METHODS: This was a prospective cohort study including 274 pregnant women. Uncomplicated pregnancies in the third trimester (28-40 weeks) were included in the study. Maternal chronic disease, pregnancy-related disorders such as hypertension, diabetes, cholestasis, smoking, and fetal abnormalities were determined as exclusion criteria...

PURPOSE: To explore the diagnostic value of intralesional and perilesional radiomics based on multimodal ultrasound (US) images in predicting the malignant ACR TIRADS 4 thyroid nodules (TNs). METHODS: A total of 297 cases of TNs in patients who underwent preoperative thyroid grayscale US and shear wave elastography (STE) were enrolled (training cohort: n = 150, internal validation cohort: n = 77, external validation cohort: n = 70)...

Leydig cell tumor (LCT) is a rare testicular tumor. We report a case of an elderly male patient who discovered a left testicular mass during a regular health examination four years ago. The patient did not experience any significant discomfort and opted for regular follow-up visits. During the most recent visit, we performed routine ultrasound and contrast-enhanced ultrasound (CEUS) examinations. By observing the lesion's location, echogenicity, margins, vascular distribution, as well as the rapid enhancement and slow washout characteristics on contrast-enhanced ultrasound, we arrived at a diagnosis of LCT...

Hepatic hemangioma is the most prevalent benign liver tumor during the fetal and neonatal period, and its rupture poses a severe threat to newborns' lives-this article presents a case involving the spontaneous rupture of a hepatic hemangioma in a neonate. Early diagnosis through ultrasound enabled prompt treatment, resulting in the patient's timely discharge.

PURPOSE: Superb microvascular imaging (SMI) and Shear wave elastography (SWE) are newly developed ultrasonographic diagnostic tools used to support the diagnosis of De Quervain tenosynovitis (DQT). The aim of this study was to examine the capacity to differentiate between the wrist with DQT and the healthy wrist, as well as the potential for predicting the disease's severity using B-mode ultrasonography, SWE, and SMI. METHODS: A total of 19 cases with unilateral clinical DQT were included in the prospective study...

Single fetal demise in monochorionic gestations in the 2nd and 3rd trimester is associated with adverse outcomes for the co-twin. We present a case of single demise in a monochorionic gestation in the 1st trimester with evidence of subsequent hemodynamic aberrations in the co-twin, supportive of feto-fetal hemorrhage occurring early in gestation.
