Fibrocartilaginous embolism (FCE) of the spinal cord is a syndrome of acute spinal cord infarction caused by embolization of fibrocartilage. The source of emboli is presumed to be extruded intervertebral disc material. FCE has been described in man, dogs and cats. While histopathologic evaluation is necessary to establish a definitive diagnosis of FCE, the MRI characteristics of this disease are such that it is no longer a diagnosis of exclusion. Typically MRI reveals cord swelling and increased T2 signal (secondary to edema) in the acute phase of a case of fibrocartilaginous embolization. Later, there is cord atrophy and heterogeneous signal intensity, typical of infarction.

Based on a literature review of histologically confirmed cases in dogs, this acute non progressive spinal cord infarction appears to have a high incidence in large breeds of dogs and a high predilection for the spinal intumescences. Furthermore these cases are often associated with trauma or exercise.
