OBJECTIVE We report 54 patients with histologically evaluated musculoskeletal masses who underwent grey-scale and contrast-enhanced ultrasound (CEUS), followed by ultrasound-guided biopsy. We hypothesise that the definition of a CEUS-based enhancement pattern improves the characterisation of tumour malignancy. METHODS Fifty-four patients with soft-tissue(More)
High resolution ultrasound (HR-US) including color Doppler ultrasound (CD-US), power Doppler ultrasound (PD-US), and spectral wave analysis (SWA), is a broadly available, non-invasive and relatively low-cost modality without ionizing radiation. It is increasingly used for initial assessment of an ambiguous musculoskeletal soft-tissue lesion and for(More)
OBJECTIVE Traumatic knee dislocation needs immediate surgical repair to restore joint function. A concomitant traction injury of the peroneal nerve is reported to exist in up to 25% of cases and is often overlooked initially. In patients with major nerve lesions, immediate surgical nerve repair might be necessary to avoid irreversible loss of neural(More)
OBJECTIVE To assess the feasibility of ultrasonography of femoral nerves in a cadaveric specimen, healthy volunteers, and patients. METHODS In 1 unembalmed cadaveric specimen (female, 90 years) and 20 healthy volunteers (9 male and 11 female, 18-50 years; n = 40 scans), the topographic features, cross-sectional shapes (oval or triangular), and(More)
Peripheral nerve tumors are not frequent, but due to their association with a nerve they are somewhat special. They may be encountered incidentally during evaluation of a soft-tissue mass or when a nerve lesion is clinically suspected and the recognition of such a lesion and its differential diagnosis is key for successful therapy and patient prognosis. As(More)
PURPOSE Radial nerve compression caused by crossing branches of the recurrent radial artery - so called hypertrophic "leash(es) of Henry" (LoH) - is rare. Nevertheless it is important to diagnose the type of compression neuropathy in the forearm. MATERIALS AND METHODS We report 2 subjects with unclear neuropathy of the deep branch of the radial nerve(More)
PURPOSE We report on a novel approach to the work-up of musculoskeletal lesions with addition of an ultrasound contrast agent followed by focal ultrasound-guided biopsy. MATERIALS AND METHODS In this pilot study 25 patients (age: 12-75) with unclear musculoskeletal tumors underwent grayscale ultrasound, color Doppler, contrast-enhanced ultrasound and(More)
PURPOSE Snapping ulnar nerve syndrome (dislocation of the ulnar nerve over the medial epicondyle) is one of many causes of ulnar neuropathy at the elbow. This preliminary study was performed to search for sonographic signs suggesting the presence of this condition. METHODS AND MATERIALS We retrospectively investigated 11 patients with snapping ulnar nerve(More)
High-resolution ultrasound is an excellent diagnostic modality for visualising peripheral nerves and differentiate tumours of the peripheral nerve. With high-frequency transducers (5-15 MHz), peripheral nerves can be visualised, the hypoechoic nerve fascicles, the surrounding tissue and tumourous lesions including the relation to their nerve of origin can(More)
