Parsonage-Turner Syndrome After COVID-19 Vaccination in a Child.

Parsonage-Turner syndrome (PTS) is a peripheral neuropathy involving the brachial plexus very rare in childhood. To date, no cases of PTS after COVID-19 vaccination have been reported in children. We report a case of a 15-year-old boy affected by PTS after the second dose of the BNT162b2 (Comirnaty, Pfizer-BioNTech) COVID-19 vaccine.

Parsonage-Turner syndrome (PTS; neuralgic amyotrophy) is a generally unilateral neuritis with sudden onset, severe shoulder or upper arm pain. Although the intense pain is usually self-limiting, two-thirds of patients experience progressive motor weakness, narrowed range of motion, reflex changes, dysesthesias and chronic neuropathic pain in the shoulder girdle musculature and proximal upper limb muscles. The aetiology is unclear, in addition to some idiopathic cases the most common triggers of PTS are surgery, trauma, infection or vaccination. It is reported after SARS-CoV-2 infection, and unilateral PTS has been described in some cases following different types of COVID-19 vaccines. We are currently presenting the case of a middle-aged woman who developed partial neuralgic amyotrophy on the right shoulder one month after receiving the second dose of the BNT162b2 COVID-19 mRNA vaccine (Pfizer-BioNTech), and seven months later the symptoms appeared in the contralateral upper limb. The diagnosis of PTS was also confirmed by magnetic resonance and electrodiagnostic examination. The PTS is not an uncommon condition, but in the absence of knowledge it is rarely thought of. The purpose of this report is to draw attention to the possibility of PTS in shoulder or upper arm pain following both SARS-CoV-2 infection and COVID-19 vaccination, as early diagnosis and adequate therapy may help to shorten the course of the disease.

Associations of neuralgic amyotrophy with COVID-19 vaccination: Disproportionality analysis using the World Health Organization pharmacovigilance database.

INTRODUCTION/AIMS: There are limited studies on the association of COVID-19 vaccination with neuralgic amyotrophy (NA). Therefore, we evaluated the association between COVID-19 vaccination and the occurrence of NA. METHODS: We explored unexpected safety signals for NA related to COVID-19 vaccination through disproportionality analysis using VigiBase, the World Health Organization's pharmacovigilance database. RESULTS: On October 15, 2021, 335 cases of NA were identified in the database. The median time to onset of NA after vaccination was around 2 weeks. A significant signal of disproportionality of NA was observed for the ChAdOx1 nCoV-19 vaccine (AstraZeneca) (information component [IC]025  = 0.33, reporting odds ratio [ROR]025  = 1.30) and two mRNA-based COVID-19 vaccines (BNT162b2 [Pfizer and BioNTech] and mRNA-1273 [Moderna]) (IC025  = 1.74, ROR025  = 3.82) compared with the entire database. However, when compared with influenza vaccines, we did not detect any signal of disproportionality of NA for both the ChAdOx1 nCoV-19 vaccine (IC025  = -2.71, ROR025  = 0.05) and mRNA-based COVID-19 vaccines (IC025  = -1.38, ROR025  = 0.13). DISCUSSION: A weak association was observed between NA and COVID-19 vaccines. However, the risk did not surpass that of influenza vaccines.

Diaphragmatic Dysfunction due to Neuralgic Amyotrophy After SARS-CoV-2 Vaccination: A Case Report.

Neuralgic amyotrophy is an idiopathic neuropathy characterized by acute-onset pain, typically in the upper extremity or shoulder, followed by weakness of the associated muscles. Phrenic nerve involvement is rare. We report a 63-year-old man who presented with dyspnea and right shoulder pain after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. His chest radiograph showed an elevated right hemidiaphragm that was absent before vaccination. A pulmonary function test showed a restrictive pattern with a significant reduction (40%) in forced vital capacity in the supine position. Diaphragm ultrasonography revealed a reduction in both diaphragmatic excursion and a thickening fraction of the right hemidiaphragm. Electrophysiological studies suggested a right upper brachial plexopathy. Considering the temporal relationship between the vaccination and absence of other causes, SARS-CoV-2 vaccination was thought to be the reason for neuralgic amyotrophy with diaphragmatic dysfunction. As there was no evidence of hypoventilation or sleep disturbance that may require noninvasive ventilation, the patient was followed with conservative treatment with analgesics. During 8 months of follow-up, his shoulder pain was relieved significantly but dyspnea improved only slightly. Neuralgic amyotrophy is an under-diagnosed etiology of diaphragmatic dysfunction and should be considered in patients with dyspnea and shoulder pain.

Parsonage Turner syndrome of the brachial plexus secondary to Covid-19 vaccine: A case report (preprint)

Parsonage Turner syndrome (PTS) is a peripheral inflammatory neuropathy of unknown etiology. We present a rare case of a patient with PTS post-covid-19 BNT162b2 mRNA vaccine. Symptoms occurred fifteen days after the second dose. The patient was treated with corticosteroids, analgesics and physical rehabilitation with a partial recovery.

Shoulder palsy following SARS-CoV-2 infection: two cases of typical Parsonage-Turner syndrome.

BACKGROUND AND PURPOSE: Coronavirus disease 2019 (COVID-19) is now known to cause neurological complications in both the central and the peripheral nervous system. Two new cases of typical neuralgic amyotrophy or Parsonage-Turner (PT) syndrome following coronavirus 2 infection (SARS-CoV-2) are reported here with explicit electrophysiological and imaging pathological features, underlining the possible association between COVID-19 and PT syndrome. CASE REPORTS: Case 1 was a 45-year-old schoolteacher presenting with acute pain in the right shoulder a few days after SARS-CoV-2 infection, with shoulder abduction and elbow flexion weakness. Needle electromyography showed a decrease in motor unit recruitment in the biceps brachii, and plexus magnetic resonance imaging (MRI) revealed a hyperintense signal involving the right C6 root and the superior truncus of the brachial plexus. Case 2 was a 21-year-old man hospitalized for dyspnea secondary to SARS-CoV-2 infection. Ten days after symptom onset, he presented right shoulder pain with difficulty in raising his right arm, revealing an isolated deficit of the serratus major muscle with a right scapula winging. Electrophysiological evaluation exhibited an isolated involvement of the long thoracic nerve with a neurogenic recruitment pattern in the serratus major muscle. Plexus MRI displayed a thickening and hyperintense signal involving the right long thoracic nerve. DISCUSSION: Parsonage-Turner syndrome triggered by SARS-CoV-2 seems to present clinical, electrophysiological and MRI characteristics similar to classic para-infectious PT syndrome, including the time frame between viral infection and neurological symptom onset. Conclusion SARS-CoV-2 might be a new infectious trigger of PT syndrome.

COVID-19 atypical Parsonage-Turner syndrome: a case report.

BACKGROUND: Neurological manifestations of Sars-CoV-2 infection have been described since March 2020 and include both central and peripheral nervous system manifestations. Neurological symptoms, such as headache or persistent loss of smell and taste, have also been documented in COVID-19 long-haulers. Moreover, long lasting fatigue, mild cognitive impairment and sleep disorders appear to be frequent long term neurological manifestations after hospitalization due to COVID-19. Less is known in relation to peripheral nerve injury related to Sars-CoV-2 infection. CASE PRESENTATION: We report the case of a 47-year-old female presenting with a unilateral chest pain radiating to the left arm lasting for more than two months after recovery from Sars-CoV-2 infection. After referral to our post-acute outpatient service for COVID-19 long haulers, she was diagnosed with a unilateral, atypical, pure sensory brachial plexus neuritis potentially related to COVID-19, which occurred during the acute phase of a mild Sars-CoV-2 infection and persisted for months after resolution of the infection. CONCLUSIONS: We presented a case of atypical Parsonage-Turner syndrome potentially triggered by Sars-CoV-2 infection, with symptoms and repercussion lasting after viral clearance. A direct involvement of the virus remains uncertain, and the physiopathology is unclear. The treatment of COVID-19 and its long-term consequences represents a relatively new challenge for clinicians and health care providers. A multidisciplinary approach to following-up COVID-19 survivors is strongly advised.

Parsonage-Turner Syndrome After COVID-19 Vaccination: A Case Report.

CASE: A 43-year-old man developed Parsonage-Turner syndrome shortly after receiving a COVID-19 vaccine. The patient presented to the hospital 5 days after receiving a COVID-19 vaccine to the right shoulder complaining of severe right shoulder pain, right upper extremity swelling, and weakness. Clinical examination, physical examination, and magnetic resonance imaging findings were consistent with Parsonage-Turner syndrome. CONCLUSION: It is important that Parsonage-Turner syndrome remains in the differential diagnosis in a patient with severe shoulder pain and weakness after the administration of a COVID-19 vaccine.
