“…Many potential factors associated with PTS have been reported, including infections by EpsteinBarr virus, varicella-zoster virus, cytomegalovirus, human immunodeficiency virus, Mycobacterium tuberculosis and Salmonella. Tetanus and hepatitis B immunizations have been implicated in PTS in addition to perioperative stress including lumbar punctures and herniorrhaphies, puerperium, unusual physical exercise including heavy labor, burns, medications such as abacavir and infliximab, as well as other causes [1,2]. We could not detect any of these antecedent events in the present case.…”

“…PTS can have a broad range of clinical manifestations; therefore, patients frequently present to practitioners of different subspecialties, such as orthopedics, neurology or general medicine [2]. PTS is one of the causes of severe cervicoomo-brachial pain, which physicians should be aware of in the primary care setting.…”

“…Pain is often described as extreme, sharp or hyperpathia-like thalamic pain [1]. Suprascapular and axillary nerves and their corresponding muscles are affected most frequently [2]. PTS was first defined by Parsonage and Turner in 1948 [3].…”

Parsonage-Turner syndrome (PTS), also known as neuralgic amyotrophy or brachial neuritis, consists of a complex set of symptoms including sudden onset shoulder pain, usually unilaterally, followed by progressive neurologic deficits such as motor weakness, dysesthesia and numbness. We report a case of a 45-year-old Japanese man with PTS, who was initially suspected of having orthopedic diseases, such as cervical spondylosis and suprascapular nerve entrapment syndrome. The patient presented with acute-onset severe pain in his right arm and neck, followed by muscle weakness. We diagnosed PTS by taking a detailed medical history, ruling out other differential diagnoses, and by considering the characteristic clinical symptoms and the denervation pattern identified by needle electromyography. High-dose corticosteroid therapy prednisolone (PSL) relieved the initial sharp pain and oral amitriptyline successfully relieved the residual nighttime pain. Doses of PSL and amitriptyline were tapered, pain was alleviated, and the patient returned to full-time work after discharge in one-and-a-half years. For prompt diagnosis, physicians should consider the possibility of PTS in patients with acute onset of severe arm pain or subsequent muscle weakness and muscle atrophy in the arm or shoulder girdle.

“…If there is more than one nerve involved, recovery is expected to be slower. In upper trunks lesions, prognosis is better (10,16). Exceptionally spontaneous recovery does not take place and the patient may require surgical intervention.…”

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.
