Proventriculus: hemorrhages; Spleen: necrosis.
Morphologic diagnosis:
Proventriculus: Mild acute multifocal hemorrhage. Spleen: Multifocal acute necrosis
Clinical description:
This image was taken 2 days post experimental inoculation with highly pathogenic avian influenza. With most strains of HPAI, as seen here, necrotic foci will frequently be observed on the surface of the spleen. The glands of the proventriculus may also have hemorrhagic lesions. As observed here, these hemorrhages tend to be concentrated at the junction between the proventriculus and the gizzard (ventriculus).
Pathologic description:
The mucosal surface of the proventriculus is stippled by numerous pinpoint hemorrhages. The spleen is present at the top of the image. The surface is the spleen in mottled by numerous, small, sometimes coalescing white foci.
