(Created page with "'''Staining''': HE '''Organ''': Lung '''Description''': Only a small region in the upper left corner shows healthy lung parenchyme. The rest of the slide shows inflammation of the lung interstitium, the alveolar septa. The interstitium is so thickened that the majority of the slide is interstitium, not alveolar spaces. The alveolar spaces are empty. A special cell morphology called “Owl’s eye” can be seen. These cells are enlarged and have inclusion bodies ins...")

The alveoli in the unaffected lung have their characteristic wiggly shapes. The alveoli in the inflamed interstitium are round, because the interstitium has been enlarged, which has stretched the alveolar septa.|417x417px]]'''Causes''':

Cells infected by the virus become very large, and accumulate inclusion bodies, which are aggregates of protein that are visible macroscopically.
