Cholesterol crystal embolization (CCE) is an important and often under-diagnosed cause of renal insufficiency in patients with atherosclerosis. So far, only statins are the mainstay of therapy and the role of corticosteroids is controversial. We describe a 57-year-old gentleman who presented with accelerated hypertension and renal failure three months after coronary angio-gram. Renal biopsy showed cholesterol clefts in the arteriole. Initially, management with anti-hypertensives alone (already receiving statins since angiogram) was unsuccessful. A trial of high-dose corticosteroids resulted in an improvement of the general condition in the next two days, and the serum creatinine reduced gradually to 1.6 mg/dL over the next one month. In conclusion, high-dose corticosteroids are useful in the treatment of CCE associated renal failure, especially in cases with no spontaneous recovery of function.
