“…We do not think that the radiotherapy given to our patient was the cause of his symptoms, since the cervical radiation dose was well within the accepted limits (Pallis et al, 1961). Matthews (1968) and Hassan (1976) have described a cauda equina syndrome in association with ankylosing spondylitis, which has been shown to be caused by posteriorly situated diverticula of the lumbar theca. We believe that two normal myelograms in our patient effectively negate this possibility in the cervical region in his case.…”

Background: Cauda equina syndrome (CES) is a rare neurologic complication in patients with long-standing ankylosing spondylitis (AS). MRI characteristically shows an enlarged caudal thecal sac, bone erosion and dural ectasia. Dural ectasia is more likely to occur in the posterior elements rather than the vertebral bodies. Methods: We report an uncommon case of CES in AS with formation of anterior dural ectasia. The origin of this rare pathology is analysed and relevant literatures are reviewed. Results: The patient had a 50-year history of AS and presented with weakness of his left leg but without bladder or rectal dysfunction. Radiographs of the full spine showed the classic features of AS with fusion of all spinal ligaments and bilateral sacroiliac joints. CT scanning demonstrated erosion-like lesions with marginal sclerosis in the posterior aspect of the T12 and L1 vertebral bodies. Lumbar MRI revealed anterior dural ectasia into the vertebral body, and ventral herniation of the spinal cord and adhesion to the dural sac. Conclusions: The clinical manifestations of anterior dural ectasia in AS with CES include lower limb numbness and weakness, bladder and rectal dysfunction, impotence, etc. MRI characteristically shows an enlarged caudal thecal sac, bone erosion and anterior dural ectasia at the junction of thoracolumbar and upper lumbar.

Progressive cauda equina syndrome and extensive calification/ossification of the lumbosacral meninges.

SUMMARY A patient with longstanding ankylosing spondylitis (AS) developed a cauda equina syndrome. The myelogram showed a block at the L2 level. Vertebral computerised tomography showed calcification in the centre of the spinal canal. The patient also had features suggestive of a diffuse idiopathic skeletal hyperostosis (DISH). Meningeal calcification has never been reported in AS, so we suggest that this is related to an associated DISH. Cauda equina syndrome has not been described in DISH, and calcification of meninges has not been reported in AS, so we suggest that the meningeal calcifications and associated cauda equina syndrome are related to DISH.
