Proventriculus: hemorrhages and edema.
Morphologic diagnosis:
Proventriculus, ventriculus: Multifocal acute hemorrhages and diffuse edema
Clinical description:
This image was taken 2 days post experimental inoculation with highly pathogenic avian influenza. In HPAI, the glands of the proventriculus may 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 and wall of the proventriculus is wet and glistening. Small pinpoint red foci are present within the proventricular glands. These hemorrhages are most dense at the junction of the proventriculus and the ventriculus (lower left of photo). A portion of the ventricular koilin has been peeled back (bottom center) to reveal hemorrhages in the subadjacent mucosa. Reddening of the mucosa at the esophageal/proventricular interface is also prominent.
