This ultrasonographic finding preceded the development of hematochezia and anemia, and pleural and peritoneal bleeding did not develop. Fine-needle aspirate cytology of the retroperitoneal space showed a predominance of erythrocytes, and rapid clinical recovery was noted following treatment with plasma, a whole blood transfusion, and vitamin K. Systemic coagulopathy should be considered a differential for hyperechoic retroperitoneal fat in cats, even in the absence of other clinical manifestations of hemorrhage.<\/jats:p>","DOI":"10.5326\/jaaha-ms-7503","type":"journal-article","created":{"date-parts":[[2025,11,5]],"date-time":"2025-11-05T11:30:02Z","timestamp":1762342202000},"page":"185-188","source":"Crossref","is-referenced-by-count":0,"title":["Hyperechoic
