Case Diagnosis: Patient is a 63-year-old male with Guillain-Barré Syndrome and Parsonage-Turner Syndrome following COVID-19 Vaccination

Case Description or Program Description: Eight days after receiving a viral vector COVID-19 vaccination, the patient developed low back and left thigh pain with severe right shoulder pain developing the following day. He denied recent viral illnesses, gastrointestinal symptoms, or prior right shoulder pain. Pain, weakness, and sensory changes gradually involved all four extremities. He was hospitalized and Guillain-Barré Syndrome (GBS) was confirmed by lumbar puncture. He tested negative for Campylobacter jejuni. Cervical and lumbar spine MRIs showed mild degenerative changes without stenosis or neuroforaminal impingement. Right shoulder MRI showed no abnormality. He responded to a 5-day course of IVIG. His extremity pain gradually resolved but right shoulder weakness remained. Electrodiagnostic testing six months after symptom onset showed evidence of GBS in recovery. Right shoulder girdle muscles were not tested during the first EMG. After stays at an LTAC and SNF, the patient was admitted to IPR. While at IPR, he reported debilitating right shoulder weakness and limited ROM. On exam, significant atrophy of the right deltoid, infraspinatus, and supraspinatus muscles was observed. A repeat electrodiagnostic study showed evidence of a right Parsonage-Turner syndrome (PTS) in addition to the GBS in recovery.

Setting: Inpatient Rehabilitation (IPR)

Assessment/Results: Patient’s presentation and EMG findings pointed to a concurrent occurrence of PTS and GBS after his COVID-19 vaccination. A right shoulder ultrasound-guided glenohumeral joint corticosteroid injection improved his shoulder ROM. The patient was discharged home with outpatient therapy after four weeks of IPR.

Discussion (relevance): Rare instances of GBS and Parsonage-Turner Syndrome have been reported after a COVID-19 vaccination. This appears to be the first reported case where GBS and PTS have both occurred in a patient soon after receiving a COVID-19 vaccination.

Conclusions: Concurrent PTS and GBS can develop after COVID-19 vaccine administration.

Level of Evidence: Level V
