Plain-English summary
A group of 65 dogs with splenic masses underwent surgery to remove their spleens. The study found that nearly half of these dogs had a type of cancer called hemangiosarcoma, while others had benign (non-cancerous) masses. Dogs with benign masses had a higher ratio of mass to spleen size compared to those with hemangiosarcoma. This information could help veterinarians determine whether a splenic mass is likely to be cancerous or not, which is important for treatment decisions and understanding the prognosis.

Abstract
OBJECTIVE: To determine whether mass-to-splenic volume ratio or splenic weight as a percentage of body weight was significantly different between dogs with benign versus malignant splenic masses. DESIGN: Retrospective case series. ANIMALS: 65 dogs that underwent splenectomy. PROCEDURES: Medical records of dogs examined between October 2007 and June 2008 because of a splenic mass were reviewed. Information obtained included dog age, breed, and weight; whether hemoperitoneum was present; splenic weight and dimensions (length, width, and height) at the time of splenectomy; dimensions (length, width, and height) of the splenic mass; and histologic diagnosis. Information on survival time was recorded when available. RESULTS: 30 (46%) dogs had hemangiosarcoma, 10 (15%) had other types of malignant masses, and 25 (39%) had benign masses. Dogs with benign splenic masses had a significantly higher mean mass-to-splenic volume ratio and higher mean splenic weight as a percentage of body weight than did dogs with hemangiosarcoma. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that mass-to-splenic volume ratio and splenic weight as a percentage of body weight may be useful in differentiating between hemangiosarcoma and benign lesions in dogs with splenic masses.
