Aortic thrombosis in a dog with chronic lymphocytic leukemia

Trombose aórtica em cão com leucemia linfocítica crônica

ABSTRACT:

The aim of this report was to describe a case of aortic thrombosis (AT) secondary to chronic lymphocytic leukemia (CLL). Although, different types of neoplasms are described as possible causes of aortic thrombosis, CLL was not yet considered. The dog showed signs of lameness that worsened with exercise. The diagnosis of AT was made by ultrasound examination. The diagnosis of CLL was made by necropsy, which showed the presence of small lymphocytes with the appearance of mature lymphocytes in the bone marrow, spleen, liver and kidneys. The importance of including CLL in the possible causes of AT in dogs, in addition to the suspicion of AT in cases of neuromuscular disease, was highlighted.
