title: Subarachnoid hemorrhage as a complication of systemic lupus erythematosus.
abstract: BACKGROUND
  Subarachnoid hemorrhage (SAH) is a rare complication of systemic lupus erythematosus (SLE).
  
  
  METHODS
  We made a retrospective search for patients with SLE and nontraumatic SAH from 1990 to 2006.
  
  
  RESULTS
  We found 10 patients with SLE and primary SAH of a total of 1,077 patients with SLE (0.93%); mean age of onset was 37.4 +/- 15.25 years and the mean duration of SLE at the onset of SAH was 98.3 +/- 50.32 months. SLEDAI and chronic damage scores were 3.67 +/- 5.20 (n = 9) and 2.90 +/- 1.45 (n = 10), respectively; 60% of patients had high Hunt-Hess scores and in only 50% of cases a saccular aneurysm was identified.
  
  
  CONCLUSIONS
  SAH presents in about 1% of SLE patients. Long duration of SLE and chronic damage scores might be associated risk factors.
