Abstract :To evaluate the frequency of lumbosacral transitional vertebrae insert ignore into journalissuearticles values(LSTV); on MRI in patients with backpain and clinically suspected of sacroiliitis. Sacroiliac MRI of patients who had backpain and were clinically suspicious for sacroiliitis between November 2021-March 2022 were retrospectively analyzed from the hospital database by two different radiologists. LSTV cases were identified and subgrouped according to Castellvi classification. Presence of sacroiliitis, degeneration and /or herniation of cranial segment intervertebral disc, facet joint hypertrophy, coxarthrosis and psoas atrophy were recorded. In cases where radiologists were in conflict, consensus was made. Between November 2021-March 2022, 614 sacroiliac MRIs were obtained and 81 insert ignore into journalissuearticles values(13%); had LSTV. Fifty-nine patients were female insert ignore into journalissuearticles values(72.8%);. Mean age was 43.4. The most common identified LSTV was type 1a insert ignore into journalissuearticles values(n=30, 10 right-sided, 20 left-sided);. Sacroiliitis was significantly more common in younger patients insert ignore into journalissuearticles values(p=0.04); and in males insert ignore into journalissuearticles values(p=0.009);. Disc degeneration, disc herniation, facet joint hypertrophy and psoas atrophy increased significantly with age insert ignore into journalissuearticles values(p=0.007, p=0.001, p=0.002 and p=0.013 respectively);. No correlation was found between gender or presence of sacroiliitis and any type of LSTV.LSTV may present with backpain and should be considered in patients where sacroiliitis is clinically suspected. MRI is a useful tool to identify other accompanying pathologies in these cases.
