Case of Renal Microaneurysms and Multiple Renal Infarctions in a Patient with Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is a chronic inflammatory, heterogeneous autoimmune disease characterized by autoantibody production and the potential involvement of almost every organ system. Although vasculitis usually confined to small vessels is a fairly common feature of SLE, ischemic vasculitis with an aneurysm is an uncommon feature. In particular, renal arterial microaneurysms and multiple renal infarctions are very rarely reported in patients with SLE. Furthermore, to the best of the authors' knowledge, there is no report on renal arterial microaneurysms associated with SLE in Korea. Here, this paper presents a case of renal microaneurysms and multiple renal infarctions in a 41-year-old woman with SLE.
