Acute Presentation and Long-Term Rehabilitation Follow-Up of Ischemic Myelopathy Due to Clinically Suspected Fibrocartilaginous Embolism in an Adolescent Male: A Case Report and Review.

Abstract

Ischemic myelopathy is uncommon in the pediatric population, with fibrocartilaginous embolism (FCE) being one of its rarest causes. We present the case of an otherwise healthy 17-year-old student who experienced sudden onset of severe low-back pain amidst intensive physical training, which rapidly deteriorated to complete sensory-motor paralysis of his lower limbs. He was treated with IV Methylprednisolone and anticoagulation after the initial work-up suggested spinal cord infarction. After eight days, sufficient clinical-radiological correlation was achieved to support FCE diagnosis as the most likely cause of infarction. He subsequently received inpatient rehabilitation treatment for four months, after which he was followed as an outpatient for a total period of 16 months. While significant neurological and functional gains were achieved during this period, he also experienced some worsening. This case highlights the importance both of performing a thorough assessment and being familiar with FCE as a possible differential diagnosis of spinal cord infarction in children, to facilitate its timely identification and proper acute and long-term management. This case report was prepared following CARE guidelines after obtaining the patient's written informed consent.
