| Summary: | Case summary A 4-year-old female spayed domestic shorthair cat with chronic anemia was evaluated for acute-onset lethargy, vomiting, abdominal distension, and a palpably enlarged and firm spleen. Abdominal ultrasound confirmed marked splenomegaly and concern for a splenic infarct, prompting exploratory abdominal surgery, where splenic torsion was diagnosed. A splenectomy was performed, and the cat recovered uneventfully. Splenitis was diagnosed on histopathology. Anemia improved postoperatively. The role of chronic anemia and other concurrent findings in the development of splenic torsion in this case remains unknown. Relevance and novel information Splenic torsion has not been previously reported in cats, making this the first case of its kind. In cases of splenomegaly and abnormal splenic blood flow, splenic torsion should be considered a differential diagnosis in cats.
