title: A retained Racz catheter fragment after epidural neurolysis: implications during magnetic resonance imaging.
abstract: A retained ferromagnetic catheter used for epidurolysis obscured diagnostic magnetic resonance imaging of the lumbar spine. The implications of this are discussed in light of other reports of retained catheter fragments obtained from the Food and Drug Administration Manufacturer and Facility Device Experience Database (http://www.fda.gov/cdrh/maude.html).
