Middle cerebral artery involvement in systemic lupus erythematosus presenting as a stroke--an unusual initial presentation of the disease.

Systemic lupus erythematosus (SLE) disproportionately affects the African American population and usually presents with a constellation of symptoms. Along with hematologic, musculoskeletal, serous and skin involvement, the most common causes of morbidity are attributed to altered blood rheology causing accelerated atherosclerotic vascular disease (ASVD). ASVD occurs in predominantly premenopausal women at an age where ASVD is rare or uncommon.
