A prospective observational study of 345 canines with ruptured splenic tumors suggests benign lesions are more common than previously reported

This study did not identify a statistically significant correlation between age or weight with the development of spHSA and reported an overall higher incidence of benign lesions, thus calling for an adjustment to the narrative claiming that old large-breed dogs have a higher prevalence of spHSA. The published data represent the largest prospective study on SH of splenic origin in canines and can be utilized by the practicing clinician to provide a comprehensive discussion when recommending surgical intervention.
