Advances in ultrasound technology have made it possible to gain higher spatial resolution and even depict nerves with excellent visual quality. In this article, the literature concerning sonography in the diagnosis of carpal tunnel syndrome (CTS) is critically reviewed. We searched Medline for studies on sonography in the diagnosis of CTS and used the(More)
One hundred consecutive patients with myasthenia gravis (MG) referred between 1985 and 1989 were analysed for epidemiological characteristics, evolution of early signs, delay in diagnosis, yield of diagnostic tests and effects of treatment. The female to male ratio was 1.6:1.0. Sixteen patients had a thymoma. Ocular MG occurred in 14. Associated autoimmune(More)
The aim of this study was to determine possible correlations between the clinical characteristics, electrophysiological features, and sonographic ulnar-nerve diameter in patients with ulnar neuropathy at the elbow (UNE). We prospectively performed clinical, electrodiagnostic, and sonographic studies in 102 patients having either purely sensory signs (35%)(More)
Using ultrasonography we found multiple sites with nerve enlargement along the course of the brachial plexus, median, ulnar, and radial nerves in the majority of 21 patients with multifocal motor neuropathy. Sonography and electrophysiologic studies showed more abnormalities than expected on purely clinical grounds. Moreover, sonography revealed nerve(More)
High-resolution sonography is capable of depicting peripheral nerves and the brachial plexus. In this study we review the literature on this subject. Normal peripheral nerves have a characteristic echotexture. Most nerves are readily visualized, although this is not always the case with the nerves of the lower extremity. The main pathological changes that(More)
OBJECTIVE To determine the diagnostic value of high-resolution sonography in ulnar neuropathy at the elbow (UNE). METHODS Sonographic ulnar nerve diameter measurement was compared at three levels around the medial epicondyle with a criterion standard including clinical and electrophysiologic characteristics in a cohort of 123 patients presenting with(More)
Involvement of peripheral nerves and skeletal muscles has been reported in the course of hereditary haemochromatosis (HH) but a systematic study is lacking. However, patients with HH report symptoms suggesting a possible polyneuropathy or myopathy. In this study patients with DNA proven HH were recruited from a large general teaching hospital. First, all(More)
OBJECTIVE To determine the outcome in patients with ulnar neuropathy at the elbow (UNE) treated surgically or conservatively, and the prognostic value of clinical, sonographic, and electrophysiologic features. METHODS After a median follow-up of 14 months, 69 of 84 patients initially included in a prospective blinded study on the diagnostic value of(More)
Clinical, laboratory and electrodiagnostic studies are the mainstay in the diagnosis of polyneuropathy. An accurate etiological diagnosis is of paramount importance to provide the appropriate treatment, prognosis and genetic counselling. High resolution sonography of the peripheral nervous system allows nerves to be readily visualized and to assess their(More)
OBJECTIVE To compare the diagnostic accuracy of ultrasonographic ulnar nerve diameter, cross-sectional area (CSA) and swelling ratio measurement in ulnar neuropathy at the elbow (UNE). METHODS Ultrasonographic diameter, CSA, and swelling ratio measurements were compared with a reference standard including clinical examination, electrophysiological(More)
