Cholesterol Microemboli

Cholesterol emboli involving the kidney may manifest clinically as acute kidney injury, hematuria, proteinuria (both non-nephrotic and nephrotic range), and even new-onset hypertension. This biopsy illustrates a rare example of glomerular involvement (Fig. 1). Most emboli are identified “upstream” within interlobular and/or arcuate arteries (Fig. 2). Prior to this biopsy, the patient had recently undergone an arterial catheterization procedure.
