ABSTRACT: We report a unique case
of lumbar disc herniation, in particular, with
end-plate and surrounded by extensive ossification, mimicking a tumor with
calcification. A 69-year-old female suffered from right buttock and leg pain.
Computed tomography (CT)
showed an intracanalar mass with calcification or ossification, which most
likely originated from the vertebral
body at the L1/2 level epidural space. On a T1-weighted gadolinium magnetic
resonance image, the capsule of the mass was enhanced and not only the content
of the mass but also that of the L2 vertebral body were partially and slightly
enhanced. The final pathological diagnosis was disc herniation with end-plate
fracture and secondary ossification.
A combination of these pathological conditions as accompanied by both end-plate
fractures and extensive secondary ossifications has not been previously reported. This rare
pathological condition needs to be recognized as a differential diagnosis.
