Aneurysmal bone cyst in soft tissue in a dog - Case Report

ABSTRACT This paper describes the diagnosis and treatment of a dog with a rare aneurysmal bone cyst in soft tissue. The patient was attended in the Veterinary Clinic Hospital at the Fedral University of Rio Grande do Sul due to limited mobility, weakness in hind limbs, and dyschezia for 15 days. It was already receiving medical treatment without success. Upon clinical examination a solid increase volume in the right perineal region was detected, and complementary imaging tests were requested. Radiography of the region suggested right perineal hernia or neoplasia. The dog was submitted to surgery, and a rounded and ossified tumoral structure was removed. The histopathological exam diagnosed the structure as an aneurysmal bone cyst in soft tissue, and the patient recovered fully after surgical excision.
