Venous thromboembolism (VTE) is a serious common disorder with substantial cost and morbidity to society and can be life threatening in some cases. The majority of VTE is diagnosed on lower extremity ultrasound or CT pulmonary angiography, but some cases of deep venous thrombosis (DVT) may be occasionally diagnosed on CT of the abdomen and pelvis by the alert radiologist. The purpose of our study was to determine the fraction of new/unsuspected DVTs diagnosed on CTAP and the subsequent management and clinical course of these patients...

A 44-year-old woman with a history of pulmonary embolism and abdominal echinococcosis complained of sudden thoracic pain and shortness of breath. A D-dimer of 77.5 mg/l (reference ≤0.5 mg/l) was found. Chest CT scan revealed obstruction of the right lower and middle lobe pulmonary artery (PA). Anticoagulation therapy was initiated for the presumed diagnosis of recurrent pulmonary embolism. However, due to persistent symptoms of dyspnea, follow-up CT angiography of the chest was performed 3 months later. A persistent PA obstruction was found and the presumed diagnosis of embolism was questioned...

Ultrasound examination of the chest has advanced in recent decades. This imaging modality is currently used to diagnose several pathological conditions and provides qualitative and quantitative information. Acoustic barriers represented by the aerated lungs and the bony framework of the chest generate well-described sonographic artifacts that can be used as diagnostic aids. The normal pleural line and A, B, C, E and Z lines (also known as false B lines) are artifacts with specific characteristics. Lung consolidation and pneumothorax sonographic patterns are also well established...

The use of focused ultrasound to obtain diagnostically significant information about the eye goes back to the 1950s. This review describes the historical and technological development of ophthalmic ultrasound and its clinical application and impact. Ultrasound, like light, can be focused, which is crucial for formation of high-resolution, diagnostically useful images. Focused, single-element, mechanically scanned transducers are most common in ophthalmology. Specially designed transducers have been used to generate focused, high-intensity ultrasound that through thermal effects has been used to treat glaucoma (via ciliodestruction), tumors, and other pathologies...

BACKGROUND: Inguinal hernias in women of reproductive age containing the ovary are very rare. When they occur in this age group, they are mostly associated with malformations of the urogenital system. Prompt surgical intervention is the key to ensure survival of the ovary. Here we present a case of an ectopic ovary presenting like an acute appendicitis. CASE PRESENTATION: A 16-year-old Cameroonian girl presented at our emergency service with an acute exacerbation of a mild and intermittent right iliac fossa pain of 5 days' duration...

BACKGROUND: Rectus sheath hematoma is a rare clinical diagnosis, particularly in pregnancy. Due to unspecific symptoms, misdiagnosis is likely and could potentially endanger a patient as well as her fetus. CASE PRESENTATION: A 26-year-old white woman presented with mild right-sided abdominal pain, which increased during palpation and movement, at 26 + 3 weeks' gestational age. Ultrasound imaging initially showed a round and well-demarcated structure, which appeared to be in contact with her uterine wall, leading to a suspected diagnosis of an infarcted leiomyoma...

Primary pulmonary synovial sarcoma (PPSS) is a rare disease. Diagnosis is made postoperatively following resection of the tumor. We describe the case of a 39-year-old non-smoking woman whose chest imaging revealed a heterogeneous mass (5.4 cm × 4.6 cm), with soft tissue density in the right upper lobe and pleural effusion in the right hemithorax. The tumor was enhanced on a computed tomography scan, in which enlargement of the mediastinal lymph nodes compressing the adjacent superior vena cava was observed...

BACKGROUND: Removal of the follicular content by ultrasound-guided transvaginal follicle aspiration (TVFA) may fail to induce immediate atresia and loss of function, resulting in the occurrence of residual follicles (RF). The aims of this study were to characterize the blood flow in RF and to determine the effects of the treatment with estradiol benzoate on RF fate. Lactating, cyclic Holstein-Gir crossbred cows were used. In Experiment 1, follicular wave emergence (D0) was synchronized in cows (n = 10) and follicular growth was then monitored by transrectal ultrasonography from D0 to D8, followed by TVFA of the largest follicle present on the ovaries 24 h later...

BACKGROUND/AIMS: Sonodynamic therapy (SDT) is considered a new approach for the treatment of atherosclerosis. We previously confirmed that hydroxyl acetylated curcumin (HAC) was a sonosensitizer. In this study, we investigated the mechanism of THP-1 macrophage apoptosis and autophagy induced by HAC mediated SDT (HAC-SDT). METHODS: Cell viability was measured using a CCK-8 assay. Laser scanning confocal microscopy was used to measure the levels of intracellular reactive oxygen species (ROS), sub-cellular HAC localization, BAX and cytochrome C translocation, LC3 expression, monodansylcadaverine staining and Dil-labeled oxidized low density lipoprotein (Dil-ox-LDL) uptake...
