Conclusion

Spinal epidural lesions are often seen by the radiologist on MRI. The lesions may arise from the contents of epidural space (intrinsic) or from structures outside the space  and encroach on it (extrinsic). As these may be either benign or malignant in etiology, it is important for the reader to be aware of the various imaging and clinical features that can help to differentiate these two categories of lesions. Encroachment on the thecal sac and spinal cord should be carefully assessed to prevent long term neurological sequale.
