A rare case of incidentally detected renal replacement lipomatosis

Abstract

We present a case of incidentally detected renal replacement lipomatosis in an Indian patient of 90 years who presented to us for chest evaluation. On Chest X-ray, we didn't find any chest abnormality except scoliosis. A staghorn calculus of size 5.5*3.7 cm was noted in left kidney for which a noncontrast CT scan was ordered. NCCT revealed a staghorn calculus in left renal pelvis with replacement lipomatosis, atrophic cortical parenchyma and patchy areas of low attenuation in renal parenchyma.
