Viral cytopathic changes consist of smudgy basophilic intranuclear inclusions with enlarged nuclei of infected cells. The inclusions stain positive for adenovirus (e.g., Figure 3 of PMID:29273157). Distal tubules are more commonly involved than proximal tubules. Occasionally glomerular visceral and parietal epithelial cells can be infected. There is associated acute tubular injury, often with frank tubular necrosis and destruction, with acute interstitial nephritis, often with a pleomorphic infiltrate composed of lymphocytes, histiocytes, plasma cells, and variable numbers of neutrophils, with interstitial edema and hemorrhage.
