Laparoscopic view of the lumen of the vagina. Note the pale color and "dehydrated" appearance of the vaginal mucosal folds (called crenulations). These changes are indicative of estrus.
A cervicovaginal prolapse. This condition is estrogen-responsive and often regresses with loss of estrogen. The mucous tissue may become excoriated from prolonged exposure.
Congenital malformation of the uterus. Segmental aplasia of the uterus. Both horns are dilated with trapped fluid. Cervix is closed. Bladder in the lower left corner of the image.
Vaginal cytology indicative of pyometra. Note the numerous, predominantly degenerate, neutrophils and red blood cells. Epithelial cells are of the intermediate type.
