What is a hygroma in a cat? - in detail
A hygroma in a cat is a fluid-filled swelling that typically forms over bony prominences or pressure points, such as the elbows, hocks, or other areas where repeated trauma or pressure occurs. It is a benign condition and is often referred to as a bursal cyst. Hygromas develop as a protective response to chronic friction or pressure, leading to the accumulation of fluid within a sac-like structure. In cats, this condition is less common compared to dogs but can still occur, particularly in older or less active cats that spend prolonged periods lying on hard surfaces. The fluid inside the hygroma is usually sterile and clear, but secondary infection can occur if the overlying skin becomes irritated or damaged. Symptoms may include a soft, fluctuant swelling that is generally painless unless complications arise. Diagnosis is typically based on physical examination, though imaging or fluid analysis may be performed to rule out other conditions. Treatment often involves addressing the underlying cause, such as providing softer bedding to reduce pressure, and in some cases, draining the fluid or surgical removal may be necessary. Prevention focuses on minimizing repetitive trauma to the affected area and maintaining proper weight and activity levels in the cat.
