Central nervous system involvement in systemic lupus erythematosus (SLE) is frequent and severe, however, myelopathy is rarely reported (0.8 p. 100 of SLE cases). We describe two SLE-young women. They were 21 and 37 year old, presented with acute paraplegia. CSF study showed pleocytosis and moderately elevated protein. Antinuclear, anti-DNA and anticardiolipin were positive. High dose steroids therapy induced marked improvement. The pathogenesis of myelopathy in SLE remains unclear. Anti-phospholipid antibodies may cause thrombosis and ischemic myelopathy. However, auto-antibodies directed against central nervous system constituents may be involved.
