Fibrocartilaginous embolism: a rare cause of cervical spine infarction

纤维软骨栓塞:颈椎梗死的一种罕见病因

Abstract

INTRODUCTION AND IMPORTANCE: One of the uncommon causes of ischaemic myelopathy is fibrocartilaginous embolisation, which results from the intersomatic disc nucleus pulposus becoming embolised into the spinal vasculature during Valsalva-like manoeuvres. CASE PRESENTATION: A 29-year-old female patient presented to the authors' emergency department with general weakness, dizziness, and an inability to move her right hand after a minor trauma. These symptoms deteriorated suddenly until the patient became quadriplegic. The clinical picture and MRI led to a diagnosis of fibrocartilaginous embolism. CLINICAL DISCUSSION: Fibrocartilaginous embolism is a rare cause of spine infarction. There is still little understanding of the underlying cause of FCE. Most cases occur sporadically in people without a family history of the disease, such as the authors' case, and diagnosis is based on imaging of the spinal cord and ruling out other causes of a blockage in the vascular system within the spinal cord, infectious and inflammatory causes. CONCLUSION: When a practitioner suspects that a patient may have fibrocartilaginous embolism (FCE), they should take the patient's history and do a neurological examination. An MRI is required since it is thought to be the most accurate method of diagnosing FCE.
