Male, 70 years old, with low back pain. Findings related to posterior instrumented fusion from L2 through L5 are described on the prior noncontrast lumbar MRI. On today's postcontrast examination, enhancement is seen within the facet joints at T11-12. Disc bulging and facet hypertrophy at this level result in a moderate spinal canal stenosis with slight impingement of the cord as well as moderate foraminal narrowing. No other definite pathologic enhancement is seen.
1.Demonstration of spinal canal stenosis at T11-12 due to a combination of disc disease and posterior element hypertrophy. The facets at this level are enhancing which likely indicates an arthropathy with inflammation.2.No other enhancing lesions identified in the lumbar spine. Details of posterior instrumented spinal fusion are discussed on the recent precontrast evaluation.
