Oviductal Diverticula - Close-up.
Intramucosal cysts or cystic diverticula of the oviduct. The tip of the uterine horn is on the right. These minute cysts result from a salpingitis whereby the epithelium of the free edges of the mucosal folds are denuded and these folds fuse. These cysts apparently do not prevent conception and are only found incidentally on necropsy or in slaughterhouse specimens.
