Endometrial cysts, mare


Courtesy of Dr. Patricia Sertich.

Sonogram of endometrial cysts in the base of the right horn of a uterus. The examining veterinarian should always “map” the location of any cysts when breeding a mare. Knowledge of cyst location will prevent mistaking a cyst for an early conceptus when the mare is being examined for pregnancy.
