Case Report: Removal of Spleen and Enlarged Kidney

Caine, an eight-year and eight-month old male Rottweiler, was referred to the Internal Medicine Division of the Veterinary Referral Center of Northern Virginia in July for assessment of proteinuria (protein in the urine). Caine had been seen by his regular veterinarian in June for bloodwork and urinalysis to determine if he could be on daily NSAIDs for his hip dysplasia. His bloodwork and urinalysis results were both abnormal.

The Internal Medicine Division of the Veterinary Referral Center of Northern Virginia performed an ultrasound that showed a 9 cm x 5 cm left kidney mass and a 4 ½ cm x 3 ½ cm splenic mass. Caine was then transferred to the Surgical Division to remove both the spleen and the left kidney.

Dr. Bradley removed Caine’s spleen which contained several masses and his left kidney that was extremely large. Both the spleen and kidney were sent for histopathology to determine the disease processes involved in each organ.

Fortunately the pathology on Caine’s spleen came back as a hematoma (a collection of clotted blood within the tissue). Unfortunately the pathology on his kidney came back as Leiomyosarcoma, a cancerous tumor. The pathology did show that this tumor was completely removed although there is as high as a 50% chance for metastasis.

Currently Caine is feeling much better. His parents are planning to recheck with a chest x-ray in two months to see if there is any metastasis. At that time they will also consider chemotherapy.

We hope that Caine continues to enjoy a good quality of life!
