Hwi Don Lee, Jun Geun Shin, Hoon Hyun, Bong-Ahn Yu, Tae Joong Eom
Tendons are tough, flexible, and ubiquitous tissues that connect muscle to bone. Tendon injuries are a common musculoskeletal injury, which affect 7% of all patients and are involved in up to 50% of sports-related injuries in the United States. Various imaging modalities are used to evaluate tendons, and both magnetic resonance imaging and sonography are used clinically to evaluate tendons with non-invasive and non-ionizing radiation. However, these modalities cannot provide 3-dimensional (3D) structural images and are limited by angle dependency...

Triple A (Allgrove) syndrome, an autosomal recessive disease is characterized by achalasia, alacrimia and ACTH-resistant adrenal failure with progressive neurological syndrome including central, peripheral and autonomic nervous system impairment, and mild mental retardation. The triple A syndrome gene, designated AAAS, localized on chromosome 12q 13 encodes for a 546 amino acid protein called ALADIN (Alacrimia-Achlasia-Adrenal Insufficiency and Neurologic disorder). This report relates to two sisters, aged 8 and 12 years, who had vomiting, muscle weakness, alacrimia, excessive fatigue and dysphagia...

INTRODUCTION: There are many techniques to identify vessels in perforator surgery, each with specific disadvantages. Handheld Dopplers are easy to use, but inaccurate with respect to the exact localisation of the perforator. Angio-CT is invasive, time consuming, and expensive. In contrast, duplex sonography is a reliable, easy-to-use and availabe alternative for pre-, intra-, and postoperative visualisation of vessels. Power Doppler further increases sensitivity and allows visualisation of vessels smaller than 0...

The chest wall is a vast and complex structure, hence the wide range of pathological conditions that may affect it. The aim of this publication is to discuss the usefulness of ultrasound for the diagnosis of benign lesions involving the thoracic wall. The most commonly encountered conditions include sternal and costal injuries and thoracic lymphadenopathy. Ultrasound is very efficient in identifying the etiology of pain experienced in the anterior chest wall following CPR interventions. Both available literature and the authors' own experience prompt us to propose ultrasound evaluation as the first step in the diagnostic workup of chest trauma, as it permits far superior visualization of the examined structures compared with conventional radiography...

PURPOSE: B-mode sonographic evaluation of shoulder joint in dogs provides qualitative information concerning mainly tendon and muscles structures. Although the sonographic findings of tenomuscular lesions have been described previously, their frequency in symptomatic and asymptomatic patients has not been reported yet. Aim of the study was to describe and compare qualitative ultrasonographic findings of shoulder joint in clinically symptomatic and asymptomatic dogs and to speculate which lesions might be considered major responsible for lameness...

BACKGROUND: Hemiplegic shoulder pain is common in stroke patients and can influence rehabilitation outcome. The underlying pathology can be various: in addition to impaired motor control and altered peripheral and central nervous activity, soft tissue lesions may also play an important role. It remains unclear how these pathologies may interact or correlate with each other. METHODS: This retrospective study collected data from 26 stroke patients who received sonography examination due to shoulder pain...

The technical advances in sonography of the past decade have supported the rapid improvement of high-resolution imaging, which enables the quick visualization of peripheral nerves at relatively limited costs. Recently, the possibility of visualizing the extratemporal facial nerve (FN) has been considered. This manuscript describes the first systematic evaluation in cadavers, of a novel ultrasonographic approach with this specific aim. Eight cadaveric hemifaces were evaluated by means of high-frequency ultrasound with two linear (13 and 22 MHz) and a convex transducer (6...

BACKGROUND: The superficial palmar branch of the radial artery (SPBRA) normally pierces through the thenar muscles and unites with the ulnar artery to form the superficial palmar arch. Rarely, a subcutaneous course of the SPBRA is described in which the artery lies superficial to the thenar muscles. CASE REPORT: We report about a 17-year-old female patient with pain at the thenar eminence due to a unique course of the SPBRA. Duplex sonography and magnetic resonance angiography revealed a subcutaneous course of the artery over the thenar muscles...

BACKGROUND: The increasing number of treatable hereditary neuromuscular diseases in children requires a diagnostic tool that can quickly, safely, and noninvasively identify affected patients directly after birth or when showing initial clinical symptoms. With clinical analysis alone, this is very difficult. IMAGING MODALITY: Near-field sonography of skeletal muscles has gradually become established as a successful method over the last 35 years. METHODOLOGICAL INNOVATIONS: Examination is performed using a strictly standardized protocol in isotopic muscle regions and with standardized sections and application parameters...

CLINICAL ISSUE: Inflammatory muscle diseases are quite heterogeneous and frequently a specific diagnosis is not easy. STANDARD RADIOLOGICAL METHODS: Magnetic resonance imaging (MRI) is best suited to demonstrate pattern and size of inflamed muscles. PERFORMANCE: Sensitivity of MRI in showing inflamed muscles is nearly 100%. Specificity, however, is much lower. PRACTICAL RECOMMENDATIONS: In cases of suspected bacterial myositis, sonography may be used to exclude abscess formation prior to MRI for more precise information about inflamed muscles...

Chest wall ultrasound has been awarded little interest in the literature, with chest wall anatomy described only in limited extent. The objective of this study has been to discuss the methodology of chest wall ultrasound and the sonographic anatomy of the region to facilitate professional evaluation of this complex structure. The primarily used transducer is a 7-12 MHz linear one. A 3-5 MHz convex (curvilinear) transducer may also be helpful, especially in obese and very muscular patients. Doppler and panoramic imaging options are essential...

Small supernumerary marker chromosomes (sSMC) are still a major problem in clinical cytogenetics as they cannot be identified or characterized unambiguously by conventional cytogenetics alone. On the other hand, and perhaps more importantly in prenatal settings, there is a challenging situation for counseling how to predict the risk for an abnormal phenotype, especially in cases with a de novo sSMC. Here we report on the prenatal diagnosis of a mosaic tetrasomy 18p due to presence of an sSMC in a fetus without abnormal sonographic signs...

Congenital dermoid fistulas of the anterior chest regions (CDFACRs) consist of a skin orifice at the anterior border of the sternocleidomastoid muscle with fistulas extending caudally in the subcutaneous tissue near the sternoclavicular joint. We report 2 pediatric CDFACR cases with pathognomonic sonography findings. By using sonography, we could diagnose the fistulas as CDFACRs by focusing on their location and direction and could reveal the distal side for complete resection. We suggest that sonography, which does not involve radiation or require sedation, is a better choice for the initial examination of CDFACRs than computed tomography or MRI...

Animal studies have shown that the rapid hyperemic response to external muscle compression undergoes inactivation upon repetitive stimulation, but this phenomenon has never been observed in humans. The aim of the present study was to determine whether 1) the vascular mechano-sensitivity underlying muscle compression-induced hyperemia is inactivated in an inter-stimulus interval (ISI)-dependent fashion upon repetitive stimulation, as suggested by animal studies, and 2) whether such inactivation also attenuates contraction-induced hyperemia...

This work presents an evaluation of the High Density surface Electromyogram (HD-sEMG) Probability Density Function (PDF) shape variation according to contraction level. On that account, using PDF shape descriptors: High Order Statistics (HOS) and Shape Distances (SD), we try to address the absence of a consensus for the sEMG non-Gaussianity evolution with force variation. This is motivated by the fact that PDF shape information are relevant in physiological assessment of the muscle architecture and function, such as contraction level classification, in complement to classical amplitude parameters...

Filamin B (FLNB) is a large dimeric actin-binding protein which crosslinks actin cytoskeleton filaments into a dynamic structure. Up to present, pathogenic mutations in FLNB are solely found to cause skeletal deformities, indicating the important role of FLNB in skeletal development. FLNB-related disorders are classified as spondylocarpotarsal synostosis (SCT), Larsen syndrome (LS), atelosteogenesis (AO), boomerang dysplasia (BD), and isolated congenital talipes equinovarus, presenting with scoliosis, short-limbed dwarfism, clubfoot, joint dislocation and other unique skeletal abnormalities...

BACKGROUND AND PURPOSE: High-resolution ultrasound is a valuable tool in supporting the diagnosis of multifocal motor neuropathy (MMN) but longitudinal data under therapy are lacking. METHODS: The change in peripheral nerve ultrasound pattern in patients with MMN was assessed over time. Patients with MMN received a thorough initial examination and follow-up over a period of 6-12 months using high-resolution ultrasound of the cervical roots and the nerves of the arms and legs, nerve conduction studies, Medical Research Council Sum Score (MRCSS) and Rotterdam Inflammatory Neuropathy Cause and Treatment Group (INCAT) score to evaluate changes under treatment...

The pronator teres muscle is rarely examined during a routine sonographic examination of the elbow joint. Nevertheless, it can be affected by a variety of conditions, including trauma and tumors, and can be implicated in compression of the median nerve. This pictorial essay first illustrates the anatomy and biomechanics of the pronator teres. Then we present the sonographic technique for examination, normal sonographic appearance, and anatomic variations of the pronator teres and adjacent structures as well as sonography of their main disorders...

CONTEXT: The medial head of the gastrocnemius is the third most commonly strained muscle in elite athletes after the biceps femoris and rectus femoris. The differential diagnosis of posterior calf injury includes musculoskeletal and nonmusculoskeletal causes. Classically, delineation of these injuries from one another relied primarily on historical features and physical examination findings. The utilization of musculoskeletal ultrasound (sonography) has augmented the diagnosis of these injuries by providing dynamic, real-time confirmation...

OBJECTIVES: To define the diagnostic value of high-resolution ultrasound (HRUS) of the suprascapular nerve (SSN) in the diagnosis of neuralgic amyotrophy (NA). METHODS: The cross-section areas (CSA) of the SSN at the C5 root (CSA1) and the omohyoid muscle in the midclavicular line (CSA2) were assessed bilaterally in 15 healthy volunteers and 14 patients with clinically and electrophysiologically verified NA. Receiver-operator-characteristics (ROC) curves were generated and cut-off values, sensitivity, specificity, positive (PPV) and negative predictive values (NPV), likelihood (LR) and odds ratios (OR) were calculated...
