Ankylosing spondylitis: cauda equina syndrome with multiple spinal arachnoid cysts

Abstract

A case of ankylosing spondylitis in a patient with a cauda equina syndrome is reported. A lumbar myelogram revealed erosions of the bones of the neural canal with enclosed multiple intraspinal cysts.

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

“…[1][2][3][4][5][6][7][8][9][10] Posterior saccular diverticula are seen when myelography is performed in the supine position. The CT shows erosions in the internal aspect of the posterior vertebral arch.…”

Cauda equina syndrome in ankylosing spondylitis: a report of six cases.

“…In addition, an increased incidence of multiple sclerosis in patients with ankylosing spondylitis has been described recently (Thomas et al, 1974). Eighteen cases of ankylosing spondylitis complicated by a cauda equina syndrome have been reported (Bowie and Glasgow, 1961;Hauge, 1961;Lee and Waters, 1962;McGill, 1966;Matthews, 1968;Rosenkranz, 1971; Gordon and Yudell, 1973;Russell et al, 1973;Thomas et al, 1974). These cases are reviewed in Table 1.…”
