(109,113,114) In kidney and liver, adenoviral infection is often associated with parenchymal necrosis, microabscess formation, or even granulomatous inflammation, and nuclear inclusions may be apparent on hematoxylin-eosin-stained sections, (109,113-115) described as large nuclei with basophilic inclusions and a thin rim of cytoplasm.
