Abstract

Introduction/Objective: Metastatic calcifications are reported in patients with end-stage renal disease (ESRD) in radiology literature but there are no pathologic reports regarding this clinical scenario in autopsy. Methods/Case Report: We report the case of a 27-yearold African American man with nephrotoxic injury secondary to gentamicin treatment at a young age leading to ESRD requiring dialysis who then later developed congestive heart disease and arrhythmia. Prior to the patient’s last hospitalization, he had normal breath sounds with no signs of respiratory distress, rales, or wheezing. Imaging of the chest showed a patchy density in the right lung and a large parenchymal calcification. During autopsy, the patient was found to have bilateral markedly small and atrophic kidneys (left kidney weight: 27.5 g, size: 5.7 x 4.4 x 3.0 cm and right kidney weight: 30.6 g, size: 5.9 x 4.4 x 3.1 cm). Microscopically, the kidneys showed diffuse global glomerulosclerosis, atrophy of cortex, severe interstitial fibrosis, and tubular atrophy with thickened arteries as well as many foci of calcifications. A large mass measuring 3.5 x 2.4 x 1.9 cm was identified in the right middle lobe of the lung. Sections of the mass revealed large calcifications which were confirmed microscopically. In addition, concentric heart hypertrophy was identified with heart weight of 925 g and left ventricle measuring up to 2.2 cm. Calcifications (ranging from 0.2 – 0.5 mm) were also identified on the left atrial wall as well as a 1.2 x 0.8 x 0.6 cm mitral valve nodule along with additional microcalcifications within the myocardium. Results (if a Case Study enter NA): NA Conclusion: In conclusion, our autopsy case supports previous radiologic reports that metastatic calcification can be dramatically present in the lung in patients with ESRD.
