Figure 1. Pathologic lesions associated with cytomegalovirus encephalitis. A. Isolated cytomegalic cells (arrows) in the molecular layer of the cerebellum (original magnification, x 50). B. Microglial nodule (thick arrow) with embedded cytomegalic inclusion cell (thin arrow) in the white matter of the temporal lobe. (Hematoxylin and eosin stain; original magnification, x 40.) C. Focal necrosis in medulla involving the medial lemniscus and pyramid (asterisk). (Luxol fast blue stain with hematoxylin and eosin counterstain; original magnification, x 2.5.) D. Magnified view of the edge of the lesion seen in part C. Numerous cytomegalic inclusion cells (arrows) can be seen. (Original magnification, x 40.) E. Cytomegalovirus ventriculitis. Several cytomegalic inclusion cells can be seen at the aqueduct. The ependyma is disrupted with cytomegalic cells (arrows). (Hematoxylin and eosin stain; original magnification, x 25.).
