A 45-year-old man with a raised body mass index presented with an acute history of right lower chest pain and increasing breathlessness. C reactive protein, D dimer and cardiac echocardiography were negative, with mild bibasal atelectasis the only positive reported finding from erect chest X-ray and CT pulmonary angiogram. He was discharged with antibiotics for a chest infection. He remained severely breathless and was referred to the sleep-related breathing disorders clinic. He described shoulder pain, daytime tiredness and sleeping upright due to a ââ'¬Ëœsuffocatingââ'¬â"¢ sensation...

BACKGROUND: Neuralgic amyotrophy is an inflammatory peripheral nerve disorder in which phrenic nerve involvement can lead to diaphragm paralysis. The prevalence, magnitude, and time course of diaphragm recovery are uncertain. METHODS: This study modeled the course of recovery of lung function in 16 subjects with diaphragm impairment from neuralgic amyotrophy. The first and last available vital capacity, sitting-to-supine decline in vital capacity, and maximal inspiratory pressures were compared...

OBJECTIVE: We report a case of misdiagnosed neuralgic amyotrophy (brachial plexus neuritis, Parsonage-Turner syndrome). Our primary objective is to review the scientific basis for errors in clinical reasoning. CASE REPORT: We herein report a patient in whom signs and symptoms compatible with neuralgic amyotrophy presented after shoulder surgery. The patient's brachial plexopathy was attributed incorrectly as a complication of interscalene brachial plexus block. The true diagnosis was made only after the patient developed neuralgic amyotrophy in the contralateral upper extremity after a subsequent shoulder surgery on that side, this time without a brachial plexus block...

BACKGROUND: Neuralgic amyotrophy is characterised by pain in the neck or shoulder region, followed by neuropathy of both motor and sensory nerves of the brachial plexus. The incidence of this condition is estimated at 1/1000 per year. In a rare variant of the syndrome, involvement of both phrenic nerves can occur, leading to diaphragmatic paralysis and severe orthopnoea. CASE DESCRIPTION: A 67-year-old woman was referred to us with acute orthopnoea. Imaging studies showed bilateral diaphragmatic paralysis, and electromyography (EMG) confirmed neuropathy of both phrenic nerves...

Hepatitis E is the most common cause of hepatitis worldwide. While originally considered a disease of developing countries, it is increasingly recognised in developed countries, probably related to contaminated pork meat, and where infection is often asymptomatic. However, several non-liver manifestations have become apparent, the most important of which are neurological, including Guillain-Barré syndrome (acute inflammatory demyelinating polyradiculoneuropathy (AIDP)), neuralgic amyotrophy and meningoencephalitis...

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)...

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...

INTRODUCTION: We assessed medical and surgical causes of unilateral trapezius muscle (TM) palsy and/or wasting. METHODS: Clinical and electrodiagnostic data were collected in 54 patients with TM impairment over 21 years. RESULTS: In total, 35 cases had a medical origin: neuralgic amyotrophy (NA, n = 22), idiopathic unilateral TM palsy (n = 5), regional neck radiotherapy for different conditions (n = 2), facioscapulohumeral dystrophy (FSH) (n = 4), abnormal loop of the jugular vein (n = 1), or basilar impression (n = 1)...

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...
