“…Ocorre envolvimento bilateral do plexo braquial em 10 a 30% dos doentes (16% simultâneo), embora os sintomas sejam geralmente assimétricos. 2,6,10,23 O envolvimento do lado contralateral é frequentemente encontrado com eletromiografia e não com exame clínico. 23 Os pacientes podem ainda ter disfunção autonômica e raramente características dismórficas.…”

“…Como SPT progride, um sinal em T1 intramuscular aumentado sugere atrofia com infiltração gordurosa e pode envolver um ou mais grupos musculares da cintura escapular. 10 Os músculos supra, infraespinhal, deltoide e redondo menor mais comumente exibem alterações de RM, e os nervos que suprem esses músculos muitas vezes apresentam anormalidades na EMG. 28 Outras causas de alta intensidade de sinal T2 devem ser consideradas, incluindo trauma, doenças inflamató-rias, rabidomiólise, exercício e tumores (especialmente na região do sulco superior).…”

Parsonage-Turner syndrome RESUMOA síndrome de Parsonage-Turner, neuralgia amiotrófica ou neurite do plexo braquial é uma síndrome rara, cuja causa é desconhecida. Os nervos supraescapular, axilar e seus músculos correspondentes são afetados com maior frequência. A doença apresenta uma ampla gama de manifestações clínicas, e os pacientes geralmente apresentam-se aos médicos de diferentes especialidades com queixa de dor intensa, de início súbito no ombro, que irradia para o braço ou pescoço e dura por horas ou semanas. Quando a dor desaparece, desenvolve-se uma paralisia flácida com fraqueza e atrofia muscular associada à perda sensorial da cintura escapular. O diagnóstico preciso pode ser desafiador e requer uma história completa e exame físico detalhado. Estudos de velocidade de condução nervosa e imagem auxiliam na avaliação. O tratamento consiste no controle sintomático. Os sintomas podem persistir durante mais do que um ano, mas a maioria dos pacientes evolui para resolução ao longo do tempo. Palavras-chave: neurite do plexo braquial; plexo braquial; inflamação. ABSTRACTThe Parsonage-Turner syndrome, amyotrophic neuralgia or neuritis of the brachial plexus is a rare syndrome, of unknown cause. The more frequently affected structures are the suprascapular, axillary nerves and their corresponding muscles. The disease has a wide range of clinical manifestations, and patients usually come to physicians of different specialties with intense and sudden pain complaints in the shoulder, radiating to the arm or neck and that lasts for hours or weeks. When the pain disappears, the patient develops a flaccid paralysis and muscle weakness associated with sensory loss of the shoulder girdle. Accurate diagnosis can be challenging and requires a complete history and detailed physical examination. Nerve conduction velocity and imaging studies help to evaluate the disease. Treatment consists of symptomatic control. The symptoms can persist for more than one year, but most patients recover over time.

SUMMARY:The BPL is a part of the peripheral nervous system. Many disease processes affect the BPL. In this article, on the basis of 60 patients, we reviewed MR imaging findings of subjects with brachial plexopathy. Different varieties of BPL lesions are discussed.ABBREVIATIONS: AA ϭ axillary artery; ABD ϭ abduction; ADs ϭ anterior divisions; AS ϭ anterior scalene muscle; AV ϭ axillary vein; BPL ϭ brachial plexus; CC ϭ costoclavicular space; CL ϭ clavicula; EMG, electromyelography; I ϭ inferior trunk; IS ϭ interscalene triangular space; LC ϭ lateral cord; M ϭ middle trunk; MC ϭ medial cord; MRA ϭ MR angiography; MRV ϭ MR venography; MS ϭ middle scalene; NEU ϭ neutral; PC ϭ posterior cord; PDs ϭ posterior divisions; PET ϭ positron-emission tomography; PMA ϭ pectoralis major muscle; PMI ϭ pectoralis minor muscle; RP ϭ retropectoralis minor space; S ϭ superior trunk; SA ϭ subclavian artery; STIR ϭ short tau inversion recovery; SV ϭ subclavian vein; T1WI ϭ T1-weighted imaging; T2WI ϭ T2-weighted imaging; TOS ϭ thoracic outlet syndrome; TSE ϭ turbo spin-echo M any disease processes affect the BPL, and the common lesions can vary according to the age of subjects. In neonates and adolescents, traumatic injury is common. In middle-aged and older individuals, intrinsic and extrinsic tumors of the BPL, cervical spondylosis, TOS, and inflammatory plexopathy (idiopathic, infectious, radiation-induced, immunemediated, and toxic) are common. On the basis of 60 patients, we reviewed MR imaging findings of subjects with brachial plexopathy. Different varieties of BPL lesions and imaging techniques are discussed. Anatomy of the BPLThe BPL is a part of the peripheral nervous system, responsible for innervation of the shoulder, upper extremity and upper chest muscles, and cutaneous nerves of the skin and hand, with branches to the phrenic nerve (C3-C5) for diaphragm movement and to the sympathetic ganglia via the C8 and T1 nerves. In the cervicothoracobrachial region, the BPL courses superior and posterior to the subclavian artery and vein. The subclavian vein is located at the most anterior extent, anteroinferior to the anterior scalene muscle. The subclavian artery extends along the floor of the interscalene triangle between the anterior and middle scalene muscles. The BPL has 5 segments: roots, trunks, divisions, cords, and terminal branches. The supraclavicular plexus includes roots and trunks. Through the neural foramina, roots of the BPL extend into the interscalene region, forming the superior (C5 and C6), middle (C7), and inferior (C8 and T1) trunks at the lateral border of middle scalene muscles. The retroclavicular plexus is located in the costoclavicular space, posterior to the clavicle and above the subclavian artery and vein, including the anterior and posterior division of the trunks. The infraclavicular plexus is situated in the retropectoralis minor space, lateral to the first rib, posterior to pectoralis muscles, and above the axillary artery and vein, including the 3 (medial, lateral, and posterior) cords and term...

Introduction: Recent applications in ultrasound imaging include ultrasound assessment and ultrasound guided therapeutic injections of the spine and brachial plexus. Discussion: Ultrasound is an ideal modality for these regions as it allows accurate safe and quick injection of single or multiple sites. It has the added advantages of lack of ionising radiation, and can be done without requiring large expensive radiology equipment. Conclusion: Brachial plexus pathology may be present in patients presenting for shoulder symptoms where very little is found at imaging the shoulder. It is important to understand the anatomy and normal variants that may exist to be able to recognise when pathology is present. When pathology is demonstrated it is easy to do a trial of therapy with ultrasound guided injection of steroid around the nerve lesion. This review will outline the normal anatomy and variants and common pathology, which can be amenable to ultrasound guided injection of steroid.

Parsonage-Turner Syndrome: MR Imaging Findings and Clinical Information of 27 Patients

Abstract: The suprascapular nerve was almost invariably involved (in 97% of shoulders) in patients with PTS. Axillary nerve involvement also was commonly observed (in 50% of shoulders). Subscapular nerve involvement was uncommon (in 3% of shoulders).
