Mesenchymal hamartoma of the liver is the second most common benign liver tumor of childhood. Ultrasonography demonstrates a cystic lesion that may be very large. Computed tomographic scan will further establish the location and its relationship to vascular anatomy. Most will be amenable to gross total resection with clear margins. To illustrate the radiological and gross operative features, we...
It remains challenging to accurately predict whether an individual arteriovenous fistula (AVF) will mature and be useable for haemodialysis vascular access. Current best practice involves the use of routine clinical assessment and ultrasonography complemented by selective venography and magnetic resonance imaging. The purpose of this literature review is to describe current practices in relatio...
Tendon sheath fibromas are rare, benign soft-tissue tumours and usually involve tendons of the upper extremities, particularly the fingers. The most common presentation is a painless, slow-growing swelling. Tendon sheath fibromas are composed of dense fibrocollagenous stromas with scattered, spindle-shaped fibroblasts and narrow, slit-like vascular spaces. Ultrasonography and magnetic resonance...
Percutaneous renal biopsy is a valuable diagnostic approach. While commonly safe, it is not without risk and the most feared vascular complications include hemorrhage, pseudoaneurysm, and arteriovenous fistula formation. We report a case of acute hemorrhage after renal biopsy that was immediately identified by ultrasonography and successfully treated with percutaneous perirenal thrombin injecti...
Although the color Doppler ultrasonography diagnosis of intestinal malrotation with midgut volvulus, based on the typical "whirlpool" appearance of the mesenteric vascular structures is well-defined in the peer-reviewed literature, the combination of both the angiographic illustration of these findings and the contemporary state-of-the-art imaging techniques is lacking. We report the digital su...
Various kinds of diseases may be found in the oral and maxillofacial regions and various modalities may be applied for their diagnosis, including intra-oral radiography, panoramic radiography, ultrasonography, computed tomography, magnetic resonance imaging, and nuclear medicine methods such as positron emission tomography. Of these modalities, ultrasound imaging is easy to use for the detectio...
