Presentation
Presented for polyuria and polydipsia. Check for urinary tract calculi.
Patient Data
Two lateral radiographs are available for review. There is a fat opacity mass arising from the distal extremity of the spleen, with a thin soft tissue border. The mass is located in the cranioventral abdomen caudal to the liver and spleen. No urinary calculi are visible. There is a linear structure in the cranial retroperitoneal space that may represent ureter, which was distended on ultrasound exam. The liver is mildly enlarged and extends beyond the costal arch. The remainder of the abdominal organs appear normal.
Case Discussion
Splenic mass aspirate revealed fat. Surgical removal was performed at another veterinary practice, and the mass was reportedly benign. No pathology report was available.
The dog also had left mild hydronephrosis from extralumainal ureteral obstruction.
Differential diagnosis
Differential diagnoses for the splenic mass include meylolipoma, lipoma, and liposarcoma. Hepatomegaly may be due to metabolic, inflammatory, or infiltrative disease.
