Treatment refractory acute necrotizing myelitis after COVID-19 vaccine injection: a case report.

INTRODUCTION AND IMPORTANCE

Post-vaccination myelitis is a rare and debilitating clinical situation. There are few reports of post-COVID-19 infection and vaccination neurological sequela.

CASE PRESENTATION

A 69-year-old lady was admitted to the emergency department due to weakness and hypoesthesia in her hands 1 week after the Sinopharm vaccine injection. MRI showed a cervicothoracic cord haemorrhagic lesion that deteriorated within 48 h. The clinical course was refractory to conservative treatments. She underwent an emergency cervical laminectomy as a salvage treatment. Intraoperative samples were in favour of acute necrotizing myelitis.

DISCUSSION

In the review of the literature, the inflammatory storm, vasculitis, and many unknown etiologies are deemed to be the possible causes of encephalopathy and myelitis after COVID-19 infection and vaccination. There are few cases of post-COVID-19 myelitis and hematomyelia, but this case was the first report of post-vaccination necrotizing myelitis.

CONCLUSION

Post-vaccination necrotizing myelitis is a lethal medical situation requiring intensive and emergent neurosurgical vigilance. Early clinical diagnosis in the beginning and full neurosurgical-neurological treatment armamentarium options are cornerstones of treatment paradigms. Salvage treatment options such as extensive laminectomy may play a life-saving role in treatment refractory cases of acute necrotizing myelitis.
