Fibrocartilaginous embolization to the spinal cord: serial MR imaging monitoring and pathologic study.
We report the serial MR imaging and neuropathologic findings in a patient with fibrocartilaginous embolism to the spinal cord, presumptively originating from vertebral body endplates. Extensive increased T2 signal intensity, minimal contrast enhancing foci, concomitant vertebral body bone marrow infarction, and terminal cord hemorrhagic necrosis were the main MR imaging features. Pathologic examination of the cord demonstrated arteriolar occlusions by chondrocytic thrombi resulting in hemorrhagic necrosis.
