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...

INTRODUCTION: The aim of this study was to assess the value of ultrasonography in neuralgic amyotrophy. METHODS: Fifty-three patients with 70 affected nerves were examined with high-resolution ultrasound. RESULTS: The most commonly affected nerve was the anterior interosseous (23%). Ultrasonographic abnormalities in the affected nerves, rather than in the brachial plexus, were observed, with an overall sensitivity of 74%. Findings included the swelling of the nerve/fascicle with or without incomplete/complete constriction and rotational phenomena (nerve torsion and fascicular entwinement)...

BACKGROUND AND IMPORTANCE: Hourglass-like constrictions are fascicular conditions confirmed definitively by interfascicular neurolysis. Certain peripheral nerves have vulnerable areas such as around the elbow in the posterior interosseous nerve. We report the first hourglass-like constriction in the brachial plexus supplying the radial innervated forearm musculature. Preoperative magnetic resonance imaging (MRI) findings of the brachial plexus were consistent with neuralgic amyotrophy (NA)...

Michael P Collins, Robert D Hadden
Nonsystemic vasculitic neuropathy (NSVN) is an under-recognized single-organ vasculitis of peripheral nerves that can only be diagnosed with a nerve biopsy. A Peripheral Nerve Society guideline group published consensus recommendations on the classification, diagnosis and treatment of NSVN in 2010, and new diagnostic criteria for vasculitic neuropathy were developed by the Brighton Collaboration in 2015. In this Review, we provide an update on the classification, diagnosis and treatment of NSVN. NSVN subtypes include Wartenberg migratory sensory neuropathy and postsurgical inflammatory neuropathy...

The neuralgic amyotrophy may be of difficult diagnosis, due to phenotypic variability, with different initial presentations (upper plexus multiple mononeuropathy, lumbosacral involvement, distal reached, phrenic involvement). To date, there is little guidance on these patients' therapeutic management, especially those for which neuralgic amyotrophy is triggered by hepatitis E virus (HEV-NA). The study aims to identify specific features that characterize patients bearing the neuralgic amyotrophy triggered by HEV...

Neuralgic Amyotrophy (NA) or Parsonage-Turner syndrome is an idiopathic neuropathy commonly affecting the brachial plexus. Associated phrenic nerve involvement, though recognised, is thought to be very rare. We present a case series of four patients (all male, mean age 53) presenting with dyspnoea preceded by severe self-limiting upper limb and shoulder pain, with an elevated hemi-diaphragm on clinical examination and chest X-ray. Neurological examination of the upper limb at the time of presentation was normal...

Hepatitis E virus (HEV) infections are not limited to the liver but may also affect other organs. Several diseases, including Guillain-Barré syndrome, neuralgic amyotrophy, glomerulonephritis, cryoglobulinemia, pancreatitis, lymphoma, thrombopenia, meningitis, thyroiditis and myocarditis have been observed in the context of hepatitis E. To date, the definite pathophysiological links between HEV and extrahepatic manifestations are not yet established. However, it is suggested that HEV infection might be causative based on serological studies, case series, in vitro data and animal models...

Hepatitis E is an emerging viral infection in developed countries. It can present with multiple extra-hepatic manifestations, including neuralgic amyotrophy. We report a 52-year-old man who presented with neck and shoulder pain followed by orthopnea and left arm weakness. Electrodiagnostic testing showed left phrenic neuropathy and denervation in bilateral C5 and C6 myotomes. He also had elevated liver enzymes, which led to the diagnosis of acute hepatitis E. This is the first case of neuralgic amyotrophy associated with hepatitis E in the United States...

Adult-onset brachial plexopathy can be classified into traumatic and non-traumatic aetiologies. Traumatic brachial plexopathies can affect the pre- or postganglionic segments of the plexus. Non-traumatic brachial plexopathies may be due to neoplasia, radiotherapy, thoracic outlet syndrome and idiopathic neuralgic amyotrophy. Conventional magnetic resonance imaging (MRI) is useful to localise the area of injury or disease, and identify the likely cause. This review discusses some of the common causes of adult-onset brachial plexopathy and their imaging features on MRI...

INTRODUCTION: Neuralgic amyotrophy (NA) is characterized by acute or subacute onset of shoulder and arm pain, followed by muscle atrophy and weakness, and variable sensory abnormalities. Historically, the site of inflammation has been localized to the brachial plexus, although involvement of individual nerve branches has been well recognized. METHODS: We describe ultrasound (US) findings in 2 cases with clinical presentation suggestive for NA, involving individual peripheral nerves, correlating with clinical and electrophysiological findings...

Metastasis of breast cancer is often detected through a long-term course and difficult to diagnose. We report a case of brachial plexopathy suspected to be the initial lesion of breast cancer metastasis, which was only detected by magnetic resonance (MR) neurography. A 61-year-old woman was admitted to our hospital within 2 years after operation for breast cancer because of progressive dysesthesia and motor weakness initially in the upper limb on the affected side and subsequently on the contralateral side...

INTRODUCTION: The muscles commonly affected by neuralgic amyotrophy (NA) are well known, but the location of the responsible lesions is less clear (plexus versus extraplexus). METHODS: We report the lesion locations in 281 NA patients as determined by extensive electrodiagnostic (EDX) testing. RESULTS: Our 281 patients had 322 bouts of NA, 57 of which were bilateral, for a total of 379 assessable events. A single nerve was involved in 174 (46%), and 205 (54%) were multifocal...

Neuralgic amyotrophy (NA) is characterized by sudden onset of severe pain in the shoulder/upper arm and muscle amyotrophy. Up to 60% of patients with NA are misdiagnosed as having shoulder joint pathology or cervical pathology. We report a case of a 13-year-old girl diagnosed with the hereditary form of NA (HNA). Array comparative genomic hybridization showed a maternally inherited duplication of 1.5 Mb including the entire SEPT9-gene. The girl was treated with non-steroidal anti-inflammatory drugs, corticosteroids and physiotherapy...
