The EM photomicrograph shows capillary walls that are uniform and of normal thickness with no electron dense immune complex-type deposits noted within the capillary walls or mesangium. Additionally, numerous podocyte cell bodies are present and unremarkable and epithelial foot processes show no significant effacement. At the top left of the image you can even see Bowman’s capsule and unremarkable parietal epithelium. These findings are those of a normal glomerulus by electron microscopy. No pathologic changes are present in this image.
