RT Journal Article SR Electronic T1 Lumbar Disk Pseudotumor: An Unusual Presentation of Lumbar Spinal Fracture and Stenosis JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1662 OP 1664 VO 23 IS 10 A1 Robert A. Koenigsberg A1 Perry Black A1 Scott H. Faro A1 Jeffrey Rykken YR 2002 UL http://www.ajnr.org/content/23/10/1662.abstract AB Summary: We present an unusual case of a primary lumbar disk-space mass that presumably developed secondary to a chronic hyperextension spinal fracture associated with spinal stenosis. This injury resulted in the appearance of a lumbar intervertebral disk-space mass or pseudotumor. The pseudotumor most likely resulted from a prior spinal fracture, leading to a fused hyperextension deformity in a patient with underlying chronic degenerative spinal disease.
