“…Visser et al measured the epineurial thickness of the ulnar nerve above the elbow in 26 leprosy patients with high-resolution ultrasound (Visser et al, 2012). The mean epineurial thickness was 0.77 mm in symptomatic ulnar nerves, 0.58 mm in asymptomatic ulnar nerves, and 0.49 mm in healthy controls (P = 0.0001).…”

Neuromuscular ultrasound is an emerging technology for the evaluation of conditions affecting nerve and muscle, with the majority of research focusing on focal neuropathies. Despite this focus, researchers have also investigated the ultrasonographic changes that occur in the nerves and muscles of those with more diffuse polyneuropathies and motor neuron diseases, and this review will detail the findings in these conditions. Specific findings are discussed in this paper, but general themes will also be presented and include the following: hereditary polyneuropathies show diffuse nerve enlargement whereas immune-mediated polyneuropathies show more patchy involvement; nerve enlargement is more profound in demyelinating than axonal polyneuropathies; and muscle changes in motor neuron diseases include heterogeneous increases in echogenicity, atrophy, readily detectable fasciculations, and increased subcutaneous tissue thickness.

“…Die Darstellung ,,klassischer" Nerven (N. medianus, N. ulnaris, N. radialis, N. peroneus, N. tibialis) gelingt weitestgehend unkompliziert mit einer Linearsonde ab 9-12 MHz [5,39,54]. Zur exakten Bestimmung und zur Suche nach kleineren Nervenverletzungen und bei der Untersuchung kleinerer, oberflächlicher Nerven (N. suralis, N. radialis superficialis) ist die Benutzung einer hochfrequenten Sonde bis 20 MHz sinnvoll.…”

“…Im Längsschnitt sind die einzelnen Faszikel ebenso sehr gut auszumachen, wobei eine Unterscheidung von umliegenden Muskelanteilen und Sehnen zuweilen schwierig ist (Abbildung 2). Der Nerv sollte innerhalb des echoreichen Epineurium gemessen werden [39,45,54]. Tabelle 1 gibt einen Überblick über einige Normwerte aus der Literatur.…”

“…Des Weiteren kann durch das sogenannte Tissue harmonic Imaging eine weitere Bildoptimierung erreicht werden. Auch sonst gilt es, in Anbetracht der Tatsache, dass Ultraschall eine dynamische Untersuchung ist, Sendefrequenz und Fokus zur optimalen Bilddarstellung bei Bedarf zu verändern.Zu weiteren technischen Details verweisen wir freundlicherweise auf Standardwerke zur Nervenbildgebung[39,54].…”

“…Although MRI is a superior method for evaluation of soft-tissue injury, it is limited by spatial resolution and cannot easily assess small nerves and partial and full-thickness disruption[9]. Ultrasonography now enables visualization of the fascicle, perineurium, epineurium, and surrounding tissues of the peripheral nerves and has been proven to be efficient in various clinical settings to evaluate peripheral nerve lesions[1011121314151617181920212223242526]. …”

Published data on earthquake-associated peripheral nerve injury is very limited. Ultrasonography has been proven to be efficient in the clinic to diagnose peripheral nerve injury. The aim of this study was to assess the role of ultrasound in the evaluation of persistent peripheral nerve injuries 1 year after the Wenchuan earthquake. Thirty-four patients with persistent clinical symptoms and neurologic signs of impaired nerve function were evaluated with sonography prior to surgical repair. Among 34 patients, ultrasonography showed that 48 peripheral nerves were entrapped, and 11 peripheral nerves were disrupted. There was one case of misdiagnosis on ultrasonography. The concordance rate of ultrasonographic findings with those of surgical findings was 98%. A total of 48 involved nerves underwent neurolysis and the symptoms resolved. Only five nerves had scar tissue entrapment. Preoperative and postoperative clinical and ultrasonographic results were concordant, which verified that ultrasonography is useful for preoperative diagnosis and postoperative evaluation of injured peripheral nerves.

Morphological changes of the epineurium in leprosy: A new finding detected by high‐resolution sonography

Abstract: The epineurium of the ulnar nerve can be measured with the use of HRUS, and it is often strikingly thickened in leprosy patients, especially in those with ulnar involvement.
