Uniform Splenomegaly.

A, Congested bloody spleen. This condition occurs secondary to compromises in vascular flow into and out of the spleen (e.g., torsion), from intravenous barbiturates (e.g., euthanasia or anesthesia), and from acute hyperemia due to septicemia. B, Meaty spleen. This condition may be due to proliferation of macrophages in cases of chronic septicemias, hemolytic diseases, diffuse granulomatous disease, or neoplasia (e.g., lymphoma).
