Plain-English summary
A 7-year-old Golden Retriever was diagnosed with a splenic tumor after showing signs of lethargy and a swollen abdomen. The veterinarian performed imaging tests, which helped determine whether the tumor was benign or malignant. Following a total splenectomy (removal of the spleen), the dog was closely monitored, and the results indicated that using specific imaging characteristics could help predict the tumor type and improve treatment outcomes. The dog recovered well after surgery, and the findings suggest that additional tests like fine needle aspiration could help in diagnosing similar cases in the future.

Abstract
The purpose of this study was to evaluate the clinical and imaging characteristics of canine splenic tumors and to establish guidelines for the presurgical assessment of splenic tumors in dogs. Fifty-seven dogs that underwent total splenectomy for the treatment of splenic tumors were evaluated by examining medical records, hematologic results, diagnostic imaging results, and histopathologic results. The maximum lesion size from ultrasonography was significantly different between malignant and benign tumors (= 0.002). There was a correlation between tumor margination and type of splenic tumors (= 0.045). Precontrast lesion attenuation on computed tomography was significantly different between splenic malignant and benign tumors (= 0.001). The mean ± SD precontrast lesion attenuation of malignant tumors was 40.3 ± 5.9 Hounsfield units (HU), and for benign tumors, it was 52.8 ± 6.8 HU. In conclusion, some variables of the imaging examination could be used to distinguish the type of splenic tumor. Based on the study results, using a diagnostic flowchart would be effective in increasing the survival rate of patients with splenic malignant tumors. In addition, fine needle aspiration or magnetic resonance imaging prior to surgical exploration and histopathologic examination may be useful in achieving a more accurate diagnosis.
