T1- and (predominantly) T2- hypointense lesion adjacent to the ground plate of the 2nd lumbar vertebral body with a dome-like upper border. Note the presence of degenerative disc disease (DDD) at L2/3, compared with the segments above and below.
This polyaetiologic, but mostly degenerative lesion must be differentiated from neoplastic or infectious conditions. It is probably identical to type III vertebral end plate changes in DDD, as described by Modic.
