Pyometra and Cystic Endometrial Hyperplasia
The abnormal thickening (pyometra) of the uters' lining can occur in animals at any age, although it is more common in animals that are older than six years of age. Cystic endometrial hyperplasia is a medical condition characterized by the presence of a sac inside the uterus filled with fluid and pus (cyst), causing the uterus (endometrium) to be enlarged (hyperplasia). Prognosis is often positive. However, if the cervix is closed, it can be a life threatening condition requiring immediate medical attention. This is a condition that can affect both cats and dogs.
