PURPOSE: To describe a patient with an occult isolated trapezoid fracture of the wrist. Isolated trapezoid fractures are very difficult to detect without advanced radiological imaging, since the fragment displacement does not occur in the sagittal plane. A discussion regarding the investigation of trapezoid fractures utilizing multiple imaging modalities includes the first demonstration of its detection via ultrasonography (US). METHODS: A 26-year-old male presented to a chiropractic teaching clinic with pain involving the left wrist, after vaulting over the handlebars of his bicycle 2 days prior...

Urinary schistosomiasis is a tropical infection with a high endemicity in the developing countries and is included in the list of "Neglected Tropical Diseases". It is caused by a parasitic worm, Schistosoma haematobium, and it has come into the spotlight as a major cause of urogenital disease. Furthermore, it is linked to bladder cancer and it is a predisposing factor for HIV/AIDS. In this case, we describe a bladder schistosomal disease in a young African boy with persistent macroscopic hematuria and its ultrasound diagnostic bladder imaging...

PURPOSE: Pneumonia is the third leading cause of death in children under 5 years of age worldwide. In pediatrics, both the accuracy and safety of diagnostic tools are important. Lung ultrasound (LUS) could be a safe diagnostic tool for this reason. We searched in the literature for diagnostic studies about LUS to predict pneumonia in pediatric patients using systematic review and meta-analysis. METHODS: The Medline, CINAHL, Cochrane Library, Embase, SPORTDiscus, ScienceDirect, and Web of Science databases from inception to September 2017 were searched...

PURPOSE: Previous studies suggest that anterior mitral valve leaflet (AMVL) elongation is a primary phenotypic feature in hypertrophic cardiomyopathy (HCM). Our aim was to assess AMVL length in individuals with HCM gene mutations and in healthy controls and to identify predictors of the development of HCM during follow-up. METHODS: A total of 133 HCM mutation carriers and 135 controls underwent cardiac examination including electro- and echocardiography. AMVL length was measured in the parasternal long axis and apical three chamber view during diastole...

PURPOSE: The assessment of liver fibrosis is essential in the management of patients with chronic liver diseases. Liver biopsy is considered the gold standard procedure for this purpose, though the recent development of new elastosonographic techniques to measure liver stiffness (LS) noninvasively is promising. Point quantification elastography (PQE) showed good results but less is known about the level of skill needed to obtain reliable results. The aim of the study was to evaluate the reproducibility of PQE in assessing LS in healthy subjects comparing three operators with different expertise...

PURPOSE: The sonographic evaluation of inferior vena cava diameters and its collapsibility-that is also defined as the caval index-has become a popular way to easily obtain a noninvasive estimate of central venous pressure. This is generally considered an easy sonographic task to perform, and according to the American College of Emergency Physicians (ACEP) Guidelines 25 repetitions of this procedure should be sufficient to reach proficiency. However, little is known about the learning process for this sonographic technique...

PURPOSE: Cavernous transformation of the portal vein can be missed on color Doppler exam or arterial phase cross-sectional imaging due to their slow flow and delayed enhancement. Contrast-enhanced ultrasound (CEUS) offers many advantages over other imaging techniques and can be used to successfully detect cavernous transformations of the portal vein. METHODS: A 10-month-old female was followed for repeat episodes of hematemesis. Computed tomography angiography (CTA) and magnetic resonance arteriogram (MRA) and portal venography were performed...

Generally, small quantities of adipose tissue is present in the thyroid gland. The adenolipoma of the thyroid gland is considered a rare finding. It consists in a benign, encapsulated neoplasm composed of mature adipose tissue and glandular elements. We report a case of a 71 year-old female patient presenting with swelling of the anterior neck and history of airway obstruction. Ultrasound (US) examination showed a bulky multinodular goiter which caused dislocation and compression of the trachea. The scans performed at the level of the isthmic region showed the presence of a hyperechoic oval formation with a homogeneous echostructure and regular contours; these characteristics suggested the lipomatous nature of the nodule...
