Intracardiac lymphoma in a cat: Diagnosis and response to chemotherapy treatment

Lappalainen, M; Fuentes, VL; Sargent, J; Desmas-Bazelle, I

Abstract

A three-year-old female cat presented for further investigations for pleural effusion following a short period of weight loss, lethargy and hyporexia. A computed tomography scan and echocardiography showed a right atrial wall mass, of which cytology was consistent with lymphoma. The heart was the sole organ infiltrated based upon extensive staging confirming a primary cardiac lymphoma. The cat was started on a multidrug chemotherapy protocol and achieved complete remission with a good quality of life prior to relapsing of her lymphoma in the kidneys and intestine. She died shortly after relapse, 5 months following diagnosis, with no response to the rescue chemotherapy.
