A hematoma in cats appears as a swollen, fluid-filled lump under the skin, often accompanied by bruising or discoloration. It may feel warm and tender to the touch.
What does a hematoma look like in cats? - in detail
A hematoma in cats is a collection of blood outside of the blood vessels, typically caused by trauma or injury. The appearance of a hematoma can vary depending on its size, location, and how long it has been present. Here's a detailed look at what a hematoma might appear like in cats:
-
Initial Appearance: Immediately after the injury, a hematoma may appear as a small, red or purple spot on the skin. This is due to the blood pooling under the surface of the skin. In some cases, the area might feel warm to the touch because of increased blood flow to the injured site.
-
Swelling: As more blood accumulates, the affected area will begin to swell. The swelling can be quite significant and may extend beyond the initial injury site. This swelling is usually firm and does not change shape when pressed gently.
-
Color Changes: Over time, the hematoma will go through color changes as the blood breaks down. Initially, it might appear red or purple. Within a few days, it can turn into a dark blue or black color as the hemoglobin in the blood is broken down into methemoglobin. Eventually, it may develop a greenish hue as bilirubin forms from the further breakdown of hemoglobin.
-
Size: The size of a hematoma can range from very small (a few millimeters) to quite large (several centimeters in diameter). Larger hematomas may look like a bruise or a lump under the skin, depending on their depth and location.
-
Location: Hematomas can occur anywhere on the cat's body but are often found on areas prone to injury such as the ears, tail, legs, and back. In the case of ear hematomas, which are common in cats, the affected area may appear as a swollen pocket within the ear flap (pinna).
-
Pain and Discomfort: While some hematomas might not cause significant discomfort, others can be quite painful, especially if they are large or located in sensitive areas. Affected cats may show signs of distress such as excessive grooming of the area, restlessness, or changes in behavior.
-
Resolution: Over time, the body will naturally reabsorb the blood from a hematoma. This process can take several weeks to months, depending on the size and location of the hematoma. During this period, the color and size of the hematoma will gradually change as it resolves.
If you notice any signs of a hematoma in your cat, it is important to consult with a veterinarian. While many hematomas can heal on their own, some may require medical intervention such as draining, bandaging, or even surgery to prevent complications like infection or persistent swelling.
