We presented here a patient of autoimmune hemolytic anemia associated with systemic lupus erythematosus. This 38 year old female was admitted because of dizziness and dyspnea. In peripheral blood and bone marrow study, characteristics of autoimmune hemolytic anemia were seen. And she was well treated with prednisolone only. The general concept of autoimmune hemolytic anemia with the brief review of literature is discussed.

Acute bilateral renal cortical necrosis is a rare cause of acute reanl failure, occuring in about 2% of patients and it's prognosis is fatal. The pathophysiology of this condition is complex, but ultimately leads to the destruction of the renal cortex with sparing of the renal medulla and a thin tissue rim of under the capsule.

In this report we describe a 23-year-old female patient in whom the diagnosis was made using MR imaging during the acute initial phase of the disease. On T1-weighted images, the signal intensity of the renal cortex was increased, but the signal intensity of the renal cortex was demarcated by a rim of low signal intensity in the region of the corticomedullary junction. MR imaging is useful, noninvasive, and specific modality for an early diagnosis of acute bilateral renal cortical necrosis.
