Lumbar Interspinous Bursitis (Baastrup Disease) in a Symptomatic Population

Abstract

Lumbar interspinous bursitis (Baastrup disease) is uncommon but not infrequent in symptomatic patients undergoing lumbar spine MRI. Patients with MRI evident Baastrup disease tend to be older, have central canal stenosis, bulging discs, and anterolisthesis. Further investigations determining the clinical significance of this finding are necessary.
