    Abstract:
    Fibrocartilaginous embolism is assumed to be caused by fibrocartilaginous nucleus pulposus component migration through retrograde embolization to the spinal cord artery. Fibrocartilaginous embolism is currently not well recognized among pediatricians because of its rarity. We describe a previously healthy 15-year-old soccer player who, after kicking a ball, developed progressive weakness in both legs and urinary retention the next day. Magnetic resonance imaging revealed T2 hyperintensity in the anterior horn of the spinal cord at the Th12/L1 level with Schmorl node at the level of L1/2. We also review the previous literature on fibrocartilaginous embolism of the spinal cord in children (less than18 years age); a total of 25 pediatric patients, including our patient, were identified. The median age was 14 years, and 64% of the reviewed patients were female. The most common trigger event was intense exercise or sports. The neurological symptoms started within one day in most cases, and the time to symptom peak varied from a few hours to two weeks. The most common initial neurological symptoms were weakness or plegia (100%), followed by paresthesia or numbness (48%). Affected areas of the spinal cord were distributed evenly from the cervical to thoracolumbar regions. Although steroids and anticoagulants were most commonly used, the prognosis was quite poor (mild to severe sequelae with three deaths). Although fibrocartilaginous embolism is a very rare condition, physicians should be aware of the characteristics and include fibrocartilaginous embolism of the spinal cord in their differential diagnosis, especially for physically active patients.
