“…Acute brachial neuritis is also known as brachial plexus neuropathy, acute brachial radiculitis, Parsonage Turner syndrome and neuralgic amyotrophy [1,[12][13][14]. Brachial neuritis was previously thought to be a distinct clinical syndrome with typical symptoms, but various clinical manifestations of brachial neuritis have been described in the literature in the recent years [6,15]. Moreover, it has been postulated that an acute onset of weakness in the shoulder or arm without a known cause should be regarded as a phenotypic variant of brachial neuritis [15].…”

Magnetic resonance imaging in bilateral brachial neuritis with pure sensory involvement

Brachial neuritis is characterized by shoulder and arm pain followed by weakness and atrophy of affected muscles and sensory loss in the arm. Isolated sensory involvement of the brachial plexus is very rare. Diagnosis of brachial neuritis is usually based on clinical history and examination, with the confirmation by electrodiagnostic tests. A 72-year-old woman presented with numbness and tingling in the bilateral upper extremities. While nerve conduction examination revealed only sensory abnormalities of the bilateral upper extremities, magnetic resonance imaging (MRI) showed thickening and hyperintensity of the bilateral brachial plexus. We report a case of bilateral brachial neuritis with clinical and electrophysiological pure sensory involvement diagnosed using brachial plexus MRI. Although electrophysiological examination is thought to be the best diagnostic technique in the diagnosis of brachial neuritis, its findings sometimes indicate a distal lesion, while the involvement of the whole brachial plexus can be seen in MRI.

Özİdiyopatik brakial nörit (İBN) akut başlangıçlı omuz ağrısını, omuz kuşağı ve üst ekstremitede gelişen progresif kas güçsüzlüğü ve atrofinin takip ettiği nadir görülen bir hastalıktır. Olgu sunumu: 47 yaşında erkek hasta sol kol ve omuzda ani başlayan ve 2 aydır devam eden şiddetli ağrı şikayeti ile başvurdu. Ayrıca üst ekstremitede fizik muayene ile gösterilebilen ciddi kas güçsüzlüğü vardı. Manyetik rezonans görüntülemede (MRG) C6 seviyesinde foraminal kanalda basısı mevcuttu. Bu bulgulara göre ön tanı cerrahi girişim gerektirebilecek servikal radikülopati (SR) idi. Ancak detaylı anamnez, fizik muayene bulguları ve elektronöromiyografi (ENMG) sonuçları konservatif tedavi ile yavaş ancak progresif iyileşme gösteren İBN ile uyumlu idi. İBN tanısında kilit noktalar detaylı anamnez ve fizik muayane olsa da gereksiz girişimleri engellemek amacıyla erken ve doğru tanı için ENMG en faydalı testtir. IntroductionIdiopathic brachial neuritis (IBN) is a peripheral neuropathy, with an unknown etiology, which mostly affects the upper trunk of brachial plexus, although focal involvement of individual nerves is also seen. Although there is no consensus about the most frequently affected Idiopathic brachial neuritis (IBN) is an uncommon clinical disorder with onset of acute, aching shoulder pain, followed by progressive muscle weakness and atrophy of shoulder girdle and upper extremity. Case report: A 47 year old male patient presented with an acute onset left shoulder pain which has been lasting for two months. He had also severe upper extremity weakness demonstrated on physical examination and compression in C6 level on the left foraminal canal in imaging. According to these findings, primary diagnosis was cervical radiculopathy (CR) which may have required surgical intervention. However, detailed history of pain, physical examination findings and electroneuromyography (ENMG) results were consistent with IBN that had a slow but progressive recovery with conservative treatment. Although detailed history and physical examination are key points in the diagnosis of IBN, ENMG is the most helpful study for early and correct diagnosis which helps in avoiding unnecessary interventions.

“…Brachial neuritis (ParsonageTurner syndrome or neuralgic amyotrophy) is another entity which can present in this manner [21,36]. Brachial neuritis is usually characterized by sudden onset of pain in the shoulder region followed by weakness and atrophy in a number of possible nerve distributions, most commonly affecting multiple elements of the brachial plexus [36]. Spontaneous mononeuropathies can result from this entity and a painless subset is recognized [28,29].…”

Intraneural perineurioma is a benign peripheral nerve sheath tumor of perineurial cell origin. We present the case of an intraneural perineurioma of the median nerve in a 23-year-old woman which posed a diagnostic challenge. Ultrasonography was found to be a quick, easy, and effective screening tool for identifying the source of the deficit followed by MRI to further elucidate the lesion. We discuss surgical management options for optimizing functional outcomes when addressing such lesions.

Brachial Plexopathies: Etiology, Frequency, and Electrodiagnostic Localization

Abstract: We report the largest to date reported case series of well-characterized brachial plexopathy patients. Upper trunk was the most frequently affected site of injury. In brachial neuritis, absence of pain and antecedent viral illness is more common than described in the literature.
