The MRI images demonstrate a lumbosacral transitional vertebra (LSTV) seen as a right mega transverse process of L5 with pseudo-articulation with the sacrum.
Case Discussion
The presence of a lumbosacral transitional vertebra (LSTV) in a patient with low back pain is suggestive of Bertolotti syndrome, however, this syndrome remains controversial.
According to the Castellvi classification of lumbosacral transitional vertebrae, this case is classified type IIa.
