Masses in the Spleen: What Does It Mean? Diagnosing and Managing Hemangiosarcoma

This lecture reviews a practical approach to dogs presenting with splenic masses, with a focus on diagnosis, client communication, and management of hemangiosarcoma. Topics will include when hemangiosarcoma should be strongly suspected, when it may be less likely, and how to guide owners before a definitive diagnosis is available. The session will also cover practical diagnostic tips, surgical decision-making, chemotherapy, supportive care, and recent publications that challenge outdated assumptions about how often splenic masses represent hemangiosarcoma. Updates on emerging diagnostics, newer therapies, current chemotherapy protocols, and supplements based on recently published studies will also be discussed.

• Identify potential signs and symptoms of hemangiosarcoma, as well as other possible causes of a splenic mass in dogs, to better inform discussions with pet owners before a diagnosis is confirmed.
• Describe the diagnostic tools and procedures available for identifying hemangiosarcoma, including the advantages and limitations of each approach.
• Evaluate the available treatment options for hemangiosarcoma in dogs, including surgery, chemotherapy, and supportive care, and understand the pros and cons of each approach.
• Summarize recent developments in hemangiosarcoma research, including new diagnostic techniques and treatment approaches, to stay up to date on the latest advancements in the field.
