Abstract
Embolization from nonbacterial thrombotic endocarditis is of clinical as well as pathologic significance. Embolization to almost all organ systems has been reported, the spleen, kidneys and brain being most frequently involved. Differential diagnosis may be extensive, and accurate diagnosis is often difficult. Two cases of nonbacterial thrombotic endocarditis are presented, one demonstrating embolization to the superior mesenteric artery and kidneys, and the other, embolization to most of the pulmonary artery branches.
