Plain-English summary
A 5-year-old cat developed a recurring swelling in the right hind leg after getting an injection. The owner tried using cold packs and a bandage, but the swelling kept coming back. After further testing, a large abnormal growth was found and surgically removed. Thankfully, the cat did not have any more issues during a five-month follow-up, and the growth was identified as a chronic expanding haematoma, which is a type of blood-filled swelling.

Abstract
A 5-year-old cat developed a recurrent haematoma in the right hindlimb after receiving an intramuscular injection. Cold packs and a compressive bandage were applied without success. The haematoma resolved initially but recurred twice within a week after conservative treatment. Contrast computed tomography was performed after the second recurrence. A large cavernous lesion was found craniolateral to the right stifle. The lesion was removed surgically. No recurrence occurred during a 5 month follow-up. On histopathology the lesion was characterised as a chronic expansive haematoma. To our knowledge, this type of lesion has not previously been described in a small animal.
