Hyperechoic Retroperitoneal Fat in a Cat with Systemic Coagulopathy.

Area of Science:

• Veterinary Medicine
• Diagnostic Imaging
• Hematology

Background:

• Retroperitoneal fat hyperechogenicity on ultrasound can be a subtle indicator of disease.
• Systemic coagulopathy presents a diagnostic challenge in feline patients.
• Hemorrhage in cats can manifest in various ways, sometimes without clear external signs.

Purpose of the Study:

• To investigate the association between hyperechoic retroperitoneal fat and systemic coagulopathy in a feline patient.
• To highlight the diagnostic significance of ultrasonographic findings in cats with bleeding disorders.
• To emphasize the importance of considering coagulopathy in feline differential diagnoses.

Main Methods:

• Ultrasonographic examination of the retroperitoneal space in a 3-year-old Sphynx cat.
• Fine-needle aspirate cytology of the retroperitoneal space.
• Clinical assessment and diagnostic workup for systemic coagulopathy.
• Treatment including plasma, whole blood transfusion, and vitamin K.

Main Results:

• Hyperechoic retroperitoneal fat was identified in a cat with confirmed systemic coagulopathy.
• The ultrasonographic finding preceded clinical signs such as hematochezia and anemia.
• Cytology revealed a predominance of erythrocytes in the retroperitoneal aspirate.
• The cat showed rapid clinical improvement after therapeutic interventions.

Conclusions:

• Hyperechoic retroperitoneal fat in cats can be an early ultrasonographic sign of systemic coagulopathy.
• This finding warrants further investigation for underlying bleeding disorders, even in the absence of overt hemorrhage.
• Systemic coagulopathy should be included in the differential diagnosis for feline patients presenting with unexplained retroperitoneal fat changes on ultrasound.
