Bilateral diaphragmatic paralysis and Lyme neuroborreliosis. Ten-years of follow-up / Parálisis diafragmática bilateral y neuroborreliosis de Lyme. Diez años de seguimiento

Abstract Borrelia burgdorferi infection (Lyme disease) is one of the few identifiable causes of neuralgic amyotrophy (AN). Bilateral diaphragmatic paralysis is considered rare in borreliosis, and the pattern of long-term recovery of diaphragm function is also uncertain. Transdiaphragmatic pressure is the gold standard for diagnosing bilateral diaphragmatic paralysis, a study that has been reported on a few occasions. We pres ent a case of AN associated with borrelia infection and bilateral diaphragmatic paralysis that provides a detailed follow-up of the spirometric evolution, the maximum static pressures in the mouth, and the transdiaphragmatic pressure from the onset of symptoms and in the long term. This case allows us to know one of the possible evolutionary profiles of diaphragmatic dysfunction in AN due to borreliosis.

Resumen La infección por Borrelia burgdorferi (enfermedad de Lyme) es una de las pocas causas identificables de amiotrofia neurálgica. La parálisis diafragmática bilateral es considerada rara en la borreliosis y el patrón de recuperación a largo plazo de la función del diafragma también es incierto. La presión transdiafragmática es el patrón de oro para el diagnóstico de parálisis diafragmática bilateral, un estudio que ha sido informado en pocas ocasiones. Se presenta un caso de amiotrofia neurálgica asociado a infección por Borrelia y parálisis diafrag mática bilateral, que aporta un seguimiento detallado de la evolución espirométrica, de las presiones estáticas máximas en la boca y de la presión transdiafragmática desde el inicio de los síntomas y a largo plazo. Este caso permite conocer uno de los posibles perfiles evolutivos de la disfunción diafragmática en la amiotrofia neurálgica por borreliosis.

Daño neurológico perioperatorio. Identificación de factores de riesgo, prevención y estudios relacionados / Perioperative nerve injury. Risk factor identification, prevention and work-up

BACKGROUND: Regional anesthesia techniques can have adverse effects, like peripheral nerve injuries. This can affect the practitioner on the choice of techniques when offering multimodal analgesia. CASE REPORT: We present the case of an arthroscopic rotator cuff repair on a patient with no comorbidities who presented peripheral nerve injury during post-op. Initially thought to have occurred as a consequence of the anesthetic technique, further study of the patient revealed the injuries to have been produced by the arthroscopic surgery. CONCLUSION: There are multiple factors that influence the possibility of peripheral nerve injury associated with nerve blocks. They can be grouped as related to the patient, the anesthetic technique or the surgical technique, the latter being the most relevant. If a patient manifests signs of peripheral nerve injury high-resolution magnetic resonance of the neural tissue must be performed immediately. Sensory nerve conduction study and electromyography must be performed 4 weeks after by an expert neurologist.

INTRODUCCIÓN: La anestesia regional puede producir como efecto adverso lesiones de nervios periféricos, lo que puede hacer desistir al anestesiólogo de realizar técnicas que mejoran la analgesia multimodal. CASO CLÍNICO: Se presenta el caso de un paciente sin comorbilidades que se operó de reparación artroscópica del manguito rotador y presentó daño neurológico postoperatorio. Inicialmente se sospechó que el daño había sido producido durante la técnica anestésica, sin embargo, el estudio adecuado demostró que el daño se relacionaba con la técnica quirúrgica. CONCLUSIÓN: Existen factores que influyen en la posibilidad de daño neurológico asociado a bloqueos de nervios periféricos que pueden ser propios del paciente, de la técnica anestésica o quirúrgicos, siendo estos últimos los más relevantes. En un paciente con clínica compatible debe realizarse resonancia magnética del tejido neural de alta resolución de forma inmediata; estudio de conducción neural sensitiva y electromiografía a las 4 semanas de evolución por un neurólogo experto.

Síndrome de Parsonage-Turner en paciente sometido a cirugía de revascularización miocárdica. caso clínico / Parsonage-Turner syndrome: report of one case

We report a 59-year-old male who, three weeks after a coronary revascularization surgery, reported a sudden intense burning pain in his left upper limb. Two weeks later, he reports a paresis with difficulty to extend his left wrist and fingers. The electromyography showed a severe axonal damage of the radial nerve with distal denervation signs. This clinical picture probably corresponds to a neuralgic amyotrophy, an inflammatory disorder of the brachial plexus known by a number of terms, including Parsonage-Turner syndrome.

The effect of ketamine as adjuvant in ultrasonic guided Supraclavicular brachial plexus block

Background: in orthopedic procedures more blood is lost from raw bone and muscle surface than from identifiable blood vessels. Moderate hypotensive anesthesia was found to significantly decrease the average blood loss by nearly 40%, reduce the need for transfusion by 45% and shorten the average operating time by nearly 10%. Objective: The aim of the current study was to compare magnesium sulphate and dexmedetomidine with nitroglycerin as regard hypotensive effect as primary outcome, volume of blood loss, blood substitution and pattern of recovery as secondary outcome during lumbar spine surgery. Patients and Methods: This prospective, controlled, comperative, randomized, double blind study included a total of ninty patients aged 21-50 years of both sex, ASA I-II scheduled for elective lumber spine surgery, attending at Department of Orthopedic, AL-Azher university Hospital in Assuit as single center study. Patients have received either dexmedetomidine, magnesium sulfate or nitroglycerine. Results: There were highly significant difference (P <0.000) with duration of surgery between different study groups with duration of surgery shortest in dexmedetomidine group followed by magnesium sulfate group and then nitroglycerine group. There were highly significant differences between different study groups with fluid maintenance with higher volume in nitroglycerine group then magnesium sulfate group and then dexmedetomidine group. There were highly significant differences (P <0.000) with systolic blood pressure between study groups at A1 and hypotensive agent discontinuation with lowest systolic blood pressure in dexmedetomidine group followed by magnesium sulfate group and then nitroglycerine group. Conclusion: nitroglycerine, magnesium sulfate and dexmedetomidine could induce hypotension, but dexmedetomidine showed more favorable hemodynamic profile as regard blood pressure and heart rate

Neuralgic Amyotrophy Associated with Cytomegalovirus Infection: A Case Report

Neuralgic amyotrophy (NA) is a peripheral neuropathy, primarily involving the brachial plexus. There is a relation between antecedent infection and NA. A few cases of NA after infections such as Epstein-Barr virus, herpes zoster virus, parvovirus, human immunodeficiency virus, Borrelia, and other infections have been reported. This case report describes a 26-year-old man with motor impairment after neuropathic pain with preceding mild flu-like symptoms whose laboratory studies revealed evidence of cytomegalovirus (CMV) infection. He was diagnosed with NA associated with CMV infection. In conclusion, CMV is a rare but possible pathogen of NA.

The clinical manifestations and outcomes of neuralgic amyotrophy

Background & Objective: Although the clinical manifestations and outcomes of neuralgic amyotrophy have been previously described, some controversies remain. Thus, we evaluated clinical manifestations and outcomes of patients with neuralgic amyotrophy. Methods: We evaluated the clinical and electrodiagnostic data, and the outcomes, of 32 patients with neuralgic amyotrophy.Of the 32 patients, 26 were followed-up for one year after onset of the disease.Results:The initial symptoms were pain (50.0%), pain with weakness (21.9%), other sensory symptoms without weakness (6.3%), and painless weakness or atrophy (21.9%). The commonly involved nerves were the median (75.0%), radial (68.8%), suprascapular (50.0%), ulnar (50.0%), axillary (46.9%), and musculocutaneous (40.6%) nerves. The initial symptoms were not associated with nerve involvement. Of all patients, 59% recovered fully, 16% had residual mild weakness without functional disability, and 6% experienced persistent severe weakness and were unable to return to work. Some patients were not evaluated because they were lost to follow-up. Conclusions: Painless weakness as an initial symptom of neuralgic amyotrophy may be more common than previously noted. Of all patients, 75% enjoyed favorable outcomes by one year after disease onset. These results will be useful when planning treatment strategies and will deepen our understanding of prognosis of neuralgic amyotrophy.

Does C5 or C6 Radiculopathy Affect the Signal Intensity of the Brachial Plexus on Magnetic Resonance Neurography?

Patients with C5 or C6 radiculopathy complain of shoulder area pain or shoulder girdle weakness. Typical idiopathic neuralgic amyotrophy (INA) is also characterized by severe shoulder pain, followed by paresis of shoulder girdle muscles. Recent studies have demonstrated that magnetic resonance neurography (MRN) of the brachial plexus and magnetic resonance imaging (MRI) of the shoulder in patients with INA show high signal intensity (HSI) or thickening of the brachial plexus and changes in intramuscular denervation of the shoulder girdle. We evaluated the value of brachial plexus MRN and shoulder MRI in four patients with typical C5 or C6 radiculopathy. HSI of the brachial plexus was noted in all patients and intramuscular changes were observed in two patients who had symptoms over 4 weeks. Our results suggest that HSI or thickening of the brachial plexus and changes in intramuscular denervation of the shoulder girdle on MRN and MRI may not be specific for INA.

Enfermedad de hirayama en un adolescente / Hirayama disease observed in an adolescent

La Enfermedad de Hirayama -o amiotrofia monomélica- es una afección de baja frecuencia y escasamente reportada en la edad pediátrica. Se presenta el caso clínico de un adolescente de 15 años de edad con disminución de la fuerza muscular y pérdida de la masa muscular, que comenzó a los 10 años de edad por la mano izquierda, y le afectó posteriormente el antebrazo. Mantuvo un curso progresivo durante 3 años, para luego mantenerse estable. El electromiograma de aguja arrojó lesión de axones motores o motoneuronas dependientes de los miotomas C7-T1, y en menor grado, C5-C6. En la tomografía axial computarizada con contraste endovenoso en marcada flexión cervical, se observó desde C7-T2 una evidente ectasia venosa posmedular asimétrica, predominantemente del lado izquierdo, por congestión del plexo venoso vertebral posterior interno. En este paciente la enfermedad se detuvo espontáneamente, en otros casos es necesario limitar la motilidad de la columna con el uso de un collar cervical, y solo llegar a la cirugía en los casos más severos de evolución rápida.

Hirayama disease or monomelic amyotrophy is a low frequent, barely reported illness at pediatric ages. Here is the clinical case of 15 years-old boy that presented with reduced muscular strength and loss of muscle mass; this condition began at the age of 10 year in his left hand and then affected the forearm. The illness progressed for three years and then remained stable. The needle electromyogram showed a lesion in C7-T1 myotome-depending motor axons or motoneurons and to less extent in those C5-C6 depending ones. The venous contrast computed tomography on a marked cervical cord flexion position; it was observed an evident asymmetric postmedullary vein ectasia from the C7-T2 myotomes, mainly on the left side, caused by the internal posterior vertebral vein plexus congestion. There was spontaneous remission of the disease in this patient, but it is necessary in other cases to limit the cervical cord motility with the use of a collar and to only perform surgery in the most rapidly evolving and severe cases.

Síndrome del desfiladero torácico neurogénico causado por la arteria escapular descendente: comunicación de un caso / Neurogenic thoracic gland syndrome caused by the descending descending artery: case report

El síndrome del desfiladero torácico es una entidad clínica compleja que abarca varias situaciones donde hay compresión del paquete vásculo-nervioso que suministra las extremidades superiores en el canal cervicotorácico. El síndrome se puede dividir en neurogénico y vascular de acuerdo con la estructura comprometida, siendo la primera la más frecuente. Entre las causas descritas están las costillas cervicales, anomalías de la primera costilla, músculos anómalos o hipertrofiados, traumatismos y tumores de la región. Describimos el caso de una paciente de 47 años que presenta un cuadro de cervicobraquialgia asociado con parestesias y paresia en la mano izquierda compatible con síndrome del desfiladero torácico en que la causa de la compresión era la arteria escapular descendente. Fue realizada una revisión de la literatura siendo encontrado sólo un caso similar.

The thoracic outlet syndrome is a complex clinical entity that encompasses several situations where there is compression of the neurovascular bundle that supplies the upper limbs in the cervicothoracic channel. It can be divided in neurogenic and vascular according to the structure committed, the first being the most frequently found. Among the causes described there are cervical ribs, anomalies of the first rib, anomalous or hypertrophied muscles, trauma and tumors of the region. We report the case of a 47 year old patient who presents with a clinical picture of cervicobrachialgia associated with paresthesia and paresis on the left hand compatible with thoracic outlet syndrome in which the cause of compression was the descending scapular artery.We conducted a literature review and found only one similar case.

Brachioradial pruritus in a patient with cervical disc herniation and Parsonage-Turner syndrome

Abstract Brachioradial pruritus is a chronic sensory neuropathy of unknown etiology which affects the skin of the shoulders, arms and forearms on the insertion of the brachioradialis muscle. We describe the case of a 60-yearold woman recently diagnosed with multiple myeloma who refers paresis, severe pruritus and itching lesions on the right arm with 6 months of evolution. Investigation led to a diagnosis of Brachioradial pruritus consequent to the presence of cervical disc herniation and Parsonage-Turner syndrome. The patient started gabapentin 900mg/day with good control of itching. Corticosteroids and antihistamines are often ineffective in the treatment of BP. Gabapentin has been used with encouraging results. All patients with Brachioradial pruritus should be evaluated for cervical spine injuries.

Síndrome de Parsonage-Turner / Parsonage-Turner syndrome

OBJETIVO: Descrever os achados clínicos, eletrofisiológicos e de imagem na síndrome de Parsonage-Turner e avaliar os resultados do tratamento conservador. MÉTODOS: Foram estudados oito casos entre fevereiro de 2010 e fevereiro de 2012, com seguimento mínimo de um ano (média de 14 meses). Todos os pacientes foram submetidos ao questionário clínico e avaliados funcionalmente com o escore de Constant e Murley. Após a suspeita clínica o exame de eletroneuromiografia foi feito para confirmação diagnóstica. RESULTADOS: Oito pacientes (média de 29 anos) foram avaliados. O lado direito foi acometido em 70% dos casos e era o dominante em 80%. Todos os pacientes relataram um início súbito de dor no ombro, com duração de um a cinco dias em seis casos e de até 15 dias em dois casos. Em três casos foi observada atrofia severa do músculo deltoide. Hipotrofia dos músculos supraespinhal e infraespinhal foi observada em três casos. Escápula alada foi observada em dois casos restantes. A eletromiografia demonstrou envolvimento do nervo torácico longo nesses dois últimos casos e confirmou o envolvimento dos nervos axilar e supraescapular nos seis casos restantes. A pontuação média na escala de Constant e Murley foi de 96 no fim do tratamento conservador com medicamentos anti-inflamatórios não esteroides e fisioterapia. Seis dos oito pacientes apresentaram boa recuperação da força muscular. CONCLUSÃO: Na maioria dos casos a recuperação funcional foi boa, embora a força muscular não tenha sido completamente restaurada em alguns deles.

OBJECTIVE: To describe the clinical, electrophysiological and imaging findings from Parsonage-Turner syndrome and evaluate the results from conservative treatment. METHODS: Eight cases were studied between February 2010 and February 2012, with a minimum follow-up of one year (mean of 14 months). All the patients answered a clinical questionnaire and underwent functional evaluation using the Constant and Murley score. After clinical suspicion was raised, an electromyography examination was performed to confirm the diagnosis. RESULTS: Eight patients (mean age of 29 years) were evaluated. The right side was affected in 70% of the cases, and the dominant side in 80% of the cases. All the patients reported that their shoulder pain had started suddenly, lasting from one to five days in six cases and up to 15 days in two cases. In three cases, severe atrophy of the deltoid muscle was observed. Hypotrophy of the supraspinatus and infraspinatus muscles was observed in three cases. A winged scapula was observed in the two remaining cases. Electromyography demonstrated involvement of the long thoracic nerve in these last two cases and confirmed the involvement of the axillary and suprascapular nerves in the remaining six cases. The mean score on the Constant and Murley scale was 96 at the end of the conservative treatment with non-steroidal anti-inflammatory drugs and physiotherapy. Six of the eight patients presented good recovery of muscle strength. CONCLUSIONS: In the majority of the cases, the functional recovery was good, although muscle strength was not completely restored in some of them.

Magnetic Resonance Neurography Findings in Idiopathic Neuralgic Amyotrophy / 계명의대학술지

Idiopathic neuralgic amyotrophy (INA) is known as Parsonage-Turner syndrome or idiopathic brachial plexitis and is characterized by sudden onset of severe limb pain, followed by weakness and atrophy of limb. There is no specific tests for the diagnosis of INA. The diagnosis of INA is mainly dependent on the clinical history and electrodiagnostic study. It is often confused with more common disorders such as acute cervical radiculopathy, rotator cuff tear, or acute calcific tendinitis. A few recent reports have revealed that magnetic resonance image (MRI) of brachial plexus and shoulder can be helpful in the diagnosis of INA. We report two cases of classic INA in which MRI enhanced specificity and confidence in the diagnosis. MRI of the brachial plexus and corresponding limb as well as cervical spine should be included in patients clinically suspected of INA.

Spinal Cord Stimulation for Refractory Neuropathic Pain of Neuralgic Amyotrophy / 대한신경손상학회지

The aim of this paper was to report the effect of temporary and chronic spinal cord stimulation for refractory neuropathic pain in neuralgic amyotrophy (NA). A 35-year-old female presented with two-months history of a severe, relentless neuropathic pain of the left shoulder, forearm, palm, and fingers. The neuropathic pain was refractory to various medical treatments, including nonsteroidal anti-inflammatory drugs, opiates, epidural and stellate ganglion blocks, and typically unrelenting. The diagnosis of NA was made with the characteristic clinical history and magnetic resonance imaging. The patient underwent a temporary spinal cord stimulation to achieve an adequate pain relief because her pain was notoriously difficult to control and lasted longer than the average duration (about 4 weeks on average) of a painful phase of NA. Permanent stimulation was given with paddle lead. The neuropathic pain in her NA persisted and she continued using the spinal cord stimulation with 12 months after development of NA. The temporary spinal cord stimulation was effective in a patient with an extraordinary prolonged, acute painful phase of NA attack, and the subsequent chronic stimulation was also useful in achieving an adequate analgesia during the chronic phase of NA.

Neuralgic Amyotrophy Manifesting as Mimicking Posterior Interosseous Nerve Palsy

The upper trunk of the brachial plexus is the most common area affected by neuralgic amyotrophy (NA), and paresis of the shoulder girdle muscle is the most prevalent manifestation. Posterior interosseous nerve palsy is a rare presentation in patients with NA. It results in dropped finger on the affected side and may be misdiagnosed as entrapment syndrome or compressive neuropathy. We report an unusual case of NA manifested as PIN palsy and suggest that knowledge of clinical NA phenotypes is crucial for early diagnosis of peripheral nerve palsies.

Cirugía de salvamento de extremidades para paciente con tumor maligno de la cintura escapular. A propósito de un caso / Limb salvage surgery for patient withMalignant tumor of the shoulder girdle. A case report

Previo a los años 70, la amputación interescapulotorácica era el principal tratamiento para los tumores óseos malignos de la cintura escapular. Con la mejor comprensión del comportamiento biológico de éstos y aplicación de terapia adyuvante, 80-90% pueden ser resecados con seguridad, empleando procedimientos de salvamento de extremidades. Se trata de paciente masculino de 34 años de edad quien cursa con aumento de volumen en región escapular derecha, de un año de evolución, acompañado de dolor en articulación acromio-clavicular y limitación para movimientos de abducción y flexión. Radiológicamente, se observó área osteolítica en fosa supraespinosa de escápula derecha; la tomografía reveló lesión destructiva de acromio, cabeza humeral y tercio externo de clavícula, en gammagrama óseo: lesión única en escápula derecha; TAC de tórax sin evidencia de lesiones secundarias. Biopsia incisional reportó sarcoma de alto grado clasificado como estadío IIB de Enneking. Posterior a estudio de Angioresonancia, se decidió y realizó la cirugía de salvamento de extremidad denominada Thikoff Lindbergh tipo IVB, consistente en la resección oncológica de margen amplio de escápula, articulación glenohumeral, 2/3 externos de clavícula y 1/3 proximal de húmero derecho. La histopatología determinó bordes libres de enfermedad y el diagnóstico final fue Osteosarcoma de alto grado. Postoperatorio con excelentes resultados; es referido a oncología clínica y a fisioterapia. Aunque los osteosarcomas de huesos planos son relativamente raros, su aparición en huesos como escapula condicionan situaciones de difícil manejo, ya que la resección adecuada está sujeta a un correcto proceso de estadificación y a una técnica depurada y experimentada(AU)

Prior to the 70s, the forequarter amputation was the primary treatment for malignant bone tumors of the shoulder girdle. With better understanding of the biological behavior of these and application of adjuvant therapy, 80-90% can be safely resected using limb salvage procedures. Male patient is 34-year- old who was studying with increased volume in the right scapular region, a year of evolution, accompanied by pain in acromioclavicular joint and limitation of abduction and flexion movements. Radiologically, there was osteolytic area in right supraspinous fossa of scapula; tomography revealed destructive lesion of acromion, humeral head and the outer third of clavicle, in ganmagrama bone: single lesion in right scapula, CT scan without evidence of secondary lesions. Incisional biopsy reported high grade sarcoma classified as Enneking stage IIB. Angiography after study, it was decided and performed limb salvage surgery called Thikoff Lindbergh type IVB, consisting of oncological resection of scapula wide margin, glenohumeral joint, two thirds collarbone external third right proximal humerus. The histopathology determined disease-free edges and the final diagnosis was highgrade osteosarcoma. Postoperative with excellent results, is referred to physiotherapy and clinical oncology. Although osteosarcoma of flat bones are relatively rare, their occurrence in bone and scapula condition unwieldy situations as adequate resection is subject to proper staging process and a refined technique and experienced(AU)

Extended Neuralgic Amyotrophy Syndrome: voice therapy in one case of vocal fold paralysis / Amiotrofia Nevrálgica Estendida: fonoterapia em um caso de paralisia de prega vocal

Neuralgic Amyotrophy (NA) is a rare disturb of the peripheral nervous system that can include extreme pain, multifocal paresis and atrophy of the muscles of the upper limbs. When the nerves located outside of the brachial plexus are involved, the term Neuralgic Amyotrophy Extended (ANE) is used. Diagnosis of NA is clinical and has a series of inclusion and compatibility criteria established by the European CMT Consortium. On this study the clinical history, multidimensional vocal assessment data and the vocal techniques used in five-weeks voice therapy for one patient, professional voice, with ANE are presented. In this case, sudden and recurrent paralysis of his right vocal fold was the only manifestation of the disease. At the end of the fifth week the patient's voice was normal, the spoken and sung vocal ranges were same as before the current episode of ANE and scores of his vocal self-assessment were appropriate.

A Amiotrofia Nevrálgica (AN) é um distúrbio raro do sistema nervoso periférico que pode incluir dor extrema, paresia multifocal e atrofia dos músculos dos membros superiores. Quando há o envolvimento de nervos localizados fora do plexo braquial, o termo Amiotrofia Nevrálgica Estendida (ANE) é utilizado. O diagnóstico da AN é clínico e possui uma série de critérios de inclusão, bem como critérios de compatibilidade estabelecidos pelo European CMT Consortium. Neste estudo são apresentados a história clínica, os dados da avaliação vocal multidimensional e as técnicas vocais utilizadas na terapia vocal de cinco semanas de um paciente, profissional da voz, com ANE. A paralisia súbita e recorrente da prega vocal direita foi a única manifestação da doença. Ao término da quinta semana, a voz do paciente estava adaptada, as extensões de voz falada e cantada eram as mesmas de antes da lesão e os escores de sua autoavaliação vocal estavam adequados.

Magnetic Resonance Neurographic Findings in Classic Idiopathic Neuralgic Amyotrophy in Subacute Stage: A Report of Four Cases

Neuralgic amyotrophy (NA) is characterized by acute onset of severe pain, followed by muscular weakness and wasting of the shoulder girdle. While the diagnosis of NA mainly relies on the clinical history and examination, some investigations including electrophysiologic study and radiologic study may help to confirm the diagnosis. Magnetic resonance neurography (MRN), a new technique for the evaluation of peripheral nerve disorders, can be helpful in the diagnosis of NA. MRN presents additional benefits in comparison to conventional magnetic resonance imaging in the diagnosis of idiopathic NA (INA). In this report, we present the first four cases of classic INA diagnosed with MRN in subacute stage. MRN imaging modality should be considered in patients clinically suspected of INA.

Brachial Plexus Neuritis Associated With Streptococcus agalactiae Infection: A Case Report

Brachial plexus neuritis is reportedly caused by various factors; however, it has not been described in association with Streptococcus agalactiae. This is a case report of a patient diagnosed with brachial plexus neuritis associated with pyogenic arthritis of the shoulder. A 57-year-old man visited the hospital complaining of sudden weakness and painful swelling of the left arm. The diagnosis was pyogenic arthritis of the left shoulder, and the patient was treated with open irrigation and debridement accompanied by intravenous antibiotic therapy. S. agalactiae was isolated from a wound culture, and an electrodiagnostic study showed brachial plexopathy involving the left upper and middle trunk. Nine weeks after onset, muscle strength improved in most of the affected muscles, and an electrodiagnostic study showed signs of reinnervation. In conclusion, S. agalactiae infection can lead to various complications including brachial plexus neuritis.
