What Is Your Diagnosis?

摘要

A 12-year-old castrated male Himalayan cat was referred for evaluation because of a 1-week history of tachypnea. The cat lived indoors only and was the only cat in the household. No known history of trauma existed. Hematologic evaluation by the referring veterinarian revealed that the cat had a regenerative anemia with an Hct of 15.9% (reference range, 29% to 45%) and a reticulocyte count of 199,000 reticulocytes/(i,L (reference range, 3,000 to 50,000 reticulocytes/mul). The cat had a platelet countof 454,000 platelets/uL, which was within the reference range of 170,000 to 600,000 platelets/muL. No abnormalities had been identified on serum biochemical analysis. Radiographs of the thorax were obtained (Figure 1).
