We report a case of tumor infiltration into an intervertebral disk ima
ged at MR. The MRI appearence of a tumor infiltration into an interver
tebral disk is the same as a spondylodiscitis: loss of the internuclea
r cleft, increased signal intensity of the disk on T2 weighted imaging
. Other metastatic infiltration in vertebrae and a. primitive tumor su
ggest the diagnosis. It is confirmed by percutaneous biopsy.
