Acute paraparesis in an 8 year-old Boxer
Fibrocartilaginous embolic myelopathy (FCEM) is a common cause of spinal cord infarction, resulting in an acute, non-progressive, non-painful neurological lesion, with clincal signs that correspond to the neuroanatomic location of the lesion. The embolic material is identical to the nucleus pulposus of the intervertebral disks and can only be definitively identified histologically with special stains. The antemortem diagnosis of FCEM is based on history, clinical signs, and diagnostic exclusion of all other causes with the use of diagnostic imaging (survey radiography, myelography, computed tomography scan (CT), and/or magnetic resonance imaging (MRI). The aim for this paper is to review the common presenting complaint, pathophysiology, and diagnosis of FCEM and to describe a case of FCEM. Definitive diagnosis was based on histological findings at necropsy.
