Clinical Summary[edit]
This 48-year-old male died in a motor vehicle accident. An incidental finding at autopsy was a renal infarct which was reddish-tan in color, sharply delineated, and triangular in shape. The base of the infarct was located at the capsular surface and its apex at the corticomedullary junction.
Images[edit]
This gross photograph shows a kidney that has been transected longitudinally at autopsy. The triangular shape of an infarct is prominent on the right side of the image; the apex (arrow) of the triangle is evident at the corticomedullary junction.
This low-power photomicrograph of the kidney illustrates a sharply demarcated area of red discoloration extending from the capsule to the cortical medullary junction (arrow).
A higher-power photomicrograph shows the edge of this reddish area, illustrating coagulation necrosis (1) compared to the normal tissue (2). The necrotic tissue in this hemorrhagic, red infarct is hypereosinophilic. Compare the tubules on the right with the normal tubules seen in the left-hand portion of the slide. Note the interstitial hemorrhage which is associated with vascular leakage within this necrotic region in the tissue.
This higher-power view of the infarct demonstrates retention of the tubular structure and cellular outlines. In the lower right-hand corner is a barely identifiable glomerulus (1). Note that, although the cellular architecture is retained, there are no nuclei within the renal tubular cells. The nuclei visible in this photomicrograph are the nuclei of inflammatory cells.
This section, taken at the cortical medullary junction, illustrates a blood vessel which is filled with thrombotic material (arrow). This vessel has occluded an end artery resulting in ischemia and infarction.
