    Abstract:
    Fibrocartilagenous embolism (FCE) of the intervertebral disc represents a very rare cause of spinal infarct. Up to now only 33 others cases in human beings have been reported in the literature, most of them diagnosed post mortem. We present a 14-year-old boy who developed acute dorsal back pain after lifting a heavy gate, followed by progressive paraparesis. An MRI of the spine showed a degenerative disc at D10-D11 without compromise of the spinal canal lumen associated with an acute Schmorl's nodule situated in the superior endplate of D11. A week later, a second MRI disclosed an intraxial spinal cord lesion at D7-D8 vertebral level involving the vascular territory of the anterior spinal artery. It also showed an abnormal signal located in the posterior third of the D8 vertebral body. These clinical and neuro-radiological findings are similar to those mentioned in the literature and support the diagnosis of an anterior spinal infarct secondary to a probable fibrocartilaginous embolism. This case highlights the importance of considering this etiology among the causes of spinal cord infarct, especially in young people, and underlines the utility of MRI in its diagnosis in vivo.
