Ear problems are common in cats and dogs. Pictured below is a wonderful cat who came to the clinic for an ear problem. Please study the image then answer the following questions: What is the name of this condition? What causes it to occur?
Diagnosis: Aural Hematoma
Notice the thickened right ear on this cat. This is an aural hematoma which means an accumulation of blood within the ear flap or pinna. The pinna in dogs and cats is composed of two cartilage sheets with blood vessels in the middle. Excessive head shaking or scratching rips the cartilage apart. Blood flows out of the damaged arteries and veins into the space creating the swollen ear.
