Lymphoma affecting the urinary bladder in three dogs and a cat

Area of Science:

• Veterinary Radiology
• Veterinary Oncology
• Comparative Pathology

Background:

• Lymphoma can affect the urinary bladder in domestic animals.
• Distinguishing lymphoma from other urinary bladder neoplasms is clinically important.

Observation:

• Abdominal radiographs and ultrasound findings were analyzed in three dogs and one cat with urinary bladder lymphoma.
• Mural lesions were consistently identified ultrasonographically.

Findings:

• Common complications included hydronephrosis and hydroureter.
• Contrast radiography revealed urine leakage in two cases.
• Radiographic and ultrasonographic signs were indistinguishable from other urinary bladder neoplasms like transitional cell carcinoma.

Implications:

• Urinary bladder lymphoma should be considered in the differential diagnosis for animals presenting with urinary bladder wall thickening or mural masses.
• Accurate diagnosis is crucial for appropriate treatment and prognosis in veterinary oncology.
