I have an 18 month old Hereford bull with a large cyst on his back, it is located in front of the pelvis, just behind the ribcage covering the whole width of his back. It is approx. 10 inches in circumference and is raised about 3 inches above the normal level of his back. I am just wondering if anyone has come across this themselves or knows of anyone who may have seen it, it would be a great help to get another opinion. Thanks.
