A 13-yr-old male cheetah (Acinonyx jubatus) presented for an acute history of lateral recumbency and anorexia. Upon physical examination under general anesthesia, severe icterus was noted. A serum biochemical profile confirmed markedly elevated total bilirubin and alanine transaminase. Based on ultrasound-guided liver aspirates and cytology, a presumptive diagnosis of large granular lymphocyte hepatic lymphoma was reached. Abdominal and thoracic radiographs did not assist in reaching an antemortem diagnosis. Postmortem examination and histopathology provided a definitive diagnosis of hepatic lymphoma with acute massive hepatocelluar necrosis and hemorrhage, as well as concurrent lesions of gastric ulcers, ulcerative and sclerosing enteritis, myocardial hypertrophy, and splenic myelolipomas. Immunohistochemistry of the liver yielded CD-3 positive and CD-20 negative results, confirming lymphocytes of a T-cell lineage. Due to concern for possible retrovirus-associated disease, enzyme-linked immunosorbent assays for feline leukemia virus and feline immunodeficiency virus were performed retrospectively on a banked serum sample and yielded negative results, thus diminishing concern for the male conspecific housed in the same exhibit.
