Compressive myelopathy caused by an epidural haematoma associated with fibrocartilage embolism was diagnosed in a 2.5-year-old Hanoverian gelding. The patient showed severe ataxia with no improvement following medical therapy and a poor prognosis after myelography. An epidural mass located dorsal to the intervertebral disc between C4 and C5 was compressing the spinal cord dorsally to approximately onethird of its normal height. The epidural tissue was characterised histologically as an organised thrombus, and its major components were fibrin and macrophages with intracytoplasmic brown, iron-rich granules. Positive Alcian blue stain confirmed the presence of cartilage within the thrombus.
