BACKGROUND: The interobserver agreement in the assessment of the grade of carotid plaque neovascularization by contrast-enhanced ultrasonography is poorly established. METHOD: We examined 140 carotid plaques in 66 patients (all patients had bilateral plaques, and 8 patients had 2 plaques on one side). We performed conventional and contrast-enhanced ultrasonography to analyze the presence of carotid plaque neovascularization, which was graded by two independent observers whose interobserver agreement (κ) was evaluated according to the thickness of carotid plaque...

PURPOSE: To assess the prevalence of ectopic thyroidal thymus tissue detected by sonography (US) in children and to analyze the US features. METHODS: We retrospectively reviewed images of 216 children who had undergone a thyroid or neck US examination from February 2015 to June 2015. Lesions within or adjacent to the thyroid gland that showed echopatterns consistent with thymic tissue were diagnosed as ectopic thyroidal thymus tissue. Lesions were reviewed according to their side, location, level, size, shape, echo pattern, internal content, and vascularization...

Prenatal ultrasonography (US) in a 39 year-old woman revealed massive fetal ascites. A fetal abdomino-amniotic shunting procedure was performed. Subsequently, plain radiographs demonstrated diffuse gaseous distention of the bowel and multiple punctate calcifications in the left upper abdomen. Postnatal US examination showed multiple echogenic foci in the liver and the left upper abdomen, bowel wall thickening in the right-sided abdomen, and undescended testes. There was no intra-abdominal free air or loculated fluid collections...

Congenital imperforate hymen is probably the most common obstructive anomaly of the female reproductive tract. The accumulation of fluid in the genital tract leads to a distended uterus and vagina, causing hydrometrocolpos. Prenatal diagnosis of fetal hydrometrocolpos is uncommon, with only 22 cases reported in the literature and only a few cases of prenatal imaging of this condition available to date. The main ultrasound finding is a fetal pelvic mass posterior to the bladder and anterior to the rectum. We present the case of a 37-week female fetus with a fetal pelvic mass detected in a routine obstetric ultrasound examination, and the correlation between the prenatal and postnatal findings...

Xiuzhen Yang, Yuebin Zhang, Jingjing Ye
We report a rare case of sonographic (US) diagnosis of four water beads causing small-bowel obstruction in an 18-month-old boy. The boy presented with a 3-day history of repeated bouts of abdominal pain and vomiting, which became bilious on the last day. Abdominal US examination showed four rounded anechoic masses in the small bowel. Urgent exploratory laparotomy revealed that the obstruction was caused by three large water beads with a diameter of 2.8 cm and fragments of a fourth one. Foreign bodies should be considered in cases of small-bowel obstruction; US can be very helpful in the diagnosis of water beads in the bowel...

Severe adverse reactions to ultrasound (US) contrast agents are rare, and only a few cases of anaphylaxis following the administration of US contrast agents have been reported, often without a defined etiology. We present a case of anaphylactic reaction to the injection of an US contrast agent in a patient with systemic mastocytosis, which highlights the disorder as a possible risk factor warranting additional consideration prior to performing a contrast-enhanced US examination.

Osseous metaplasia of the endometrium is a rare condition characterized by the presence of mature or immature bone in the endometrium. Most cases present with secondary infertility following an abortion or chronic endometritis. Some patients are asymptomatic, while others have menstrual abnormalities such as menorrhagia or oligomenorrhea. Removal of the bony fragments helps in spontaneous conception. We hereby present two cases of osseous metaplasia of the endometrium with radiological and pathological correlation...

OBJECTIVE: To determine the accuracy of shear-wave elastography (SWE) to differentiate low from advanced degrees of liver fibrosis in hepatitis C patients. MATERIAL & METHOD: Consented native/transplant hepatitis C patients underwent SWE using a C1-6 MHz transducer before ultrasound (US)-guided liver biopsy. Five interpretable SWE samples were obtained from the right lobe of the liver immediately before US-guided random biopsy of the right lobe. Average kilopascal (kPa) values were compared to the meta-analysis of histological data in viral hepatitis (METAVIR) fibrosis grading...

New substances are constantly being added to the content of synthetic cannabinoids (SCs). SCs can affect the cardiovascular system and cause hypotension and bradycardia, myocardial infarction, atrial fibrillation, prolonged QTc, and Mobitz type II atrioventricular block. However, no cases associated with ventricular fibrillation (VF) have been reported to date. We report a case of a 26-year-old male patient admitted to the emergency department due to altered consciousness after SC use and requiring prolonged cardiopulmonary resuscitation due to resistant VF and cardiogenic shock...

Pseudoaneurysms of the scalp are rare. Most common etiology is trauma. The patients usually present clinically with persistent painful swelling in the scalp few days after the trauma. The lesion may or may not be pulsatile clinically. Ultrasonography (US) is the best modality to assess these pseudoaneurysms. It not only helps in the diagnosis, but also to trace the offending arterial branch and helps in treatment. We present two cases of post-traumatic scalp pseudoaneurysms which were diagnosed with US and were managed by US-guided thrombin injection...

Coronary sinus thrombosis is a rare and often overlooked diagnosis that can have fatal consequences. We report a case of acute coronary sinus thrombosis in a patient with systolic heart failure who had undergone recent right-heart catheterization. The patient presented with recurrent presyncope, syncope, and shortness of breath. An echogenic focus consistent with a coronary sinus thrombus was visualized on transthoracic echocardiography that had not been seen previously on recent imaging. The patient was managed on oral anticoagulation...

OBJECTIVE: Clinical decision making in children with heart disease relies on detailed measurements of cardiac structures using two-dimensional and M-mode echocardiography. However, no echocardiographic reference values are available for the Chinese children. We aimed to establish z-score regression equations for left heart structures in a population-based cohort of healthy Chinese Han children. METHOD: Echocardiography was performed in 545 children with a normal heart...

Amyloid goiter (AG) is defined as the diffuse enlargement of the thyroid gland resulting from extensive amyloid deposition. Imaging findings in AG may vary depending on the amount of amyloid and fat deposition. A few case reports of AG with clinically subacute thyroiditis (SAT)-like syndrome have been published. However, there have been no reports on AG mimicking SAT with clinical and imaging findings. Herein, we present a case of AG mimicking SAT with a detailed report of the clinical and imaging findings.
