Affects: Dogs
A hygroma, or a false bursa, is a discrete, fluid-filled sac that can form on the joints of dogs in response to repeated pressure, such as that from sitting on a hard surface. It is treated by draining the fluid and may be prevented by providing padded bedding.
Treatment: An untreated hygroma can develop into a large swelling that stresses the surrounding skin and becomes an open wound with the possibility of infection that is much more difficult to treat. In most cases, a hygroma is a single occurrence for an animal, but other individuals will have repeated problems with hygromas.
