Disk entry: a complication of transforaminal epidural injection--a case report.
Correctly identifying the etiology of low back pain can be challenging. The importance of making an expedient, accurate diagnosis of lumbar radicular pain cannot be overemphasized, as proper treatment is based on the outcome. The application of fluoroscopically guided, contrast enhancement during spinal injections is commonly performed, but is not without complications. Intradiskal placement of contrast dye during lumbar transforaminal epidural injection is important to identify, as serious potential complications, such as diskitis, may occur. Additionally, postprocedure assessment may not be accurate if contrast placement is not correctly identified. This case report reviews the literature on complications of transforaminal steroid injection and presents the first documentation of intradiskal placement of contrast dye in the United States. A 72-year-old man presenting with a right L4 radiculopathy underwent a fluoroscopically guided, contrast-enhanced lumbar transforaminal epidural steroid injection and experienced intradiskal placement of contrast as a complication of this procedure. Although the patient was treated prophylactically and achieved good results, the need for fluoroscopy and contrast enhancement during performance of spinal injections is reemphasized.
