Small-sized cardiac cavernous hemangioma in patient with endocarditis - an incidental finding.

Tumors of the heart and blood vessels are relatively rare. Primary cardiac hemangiomas, in particular, are very rare benign tumors of the heart, occurring at a frequency of 2.8%. To date, just over 200 cases have been documented in scientific literature. Most have been discovered incidentally during autopsies or clinical procedures for unrelated conditions. Most reports present cardiac hemangiomas as isolated cases. According to scientific data, they can appear at any age, and their clinical presentation varies depending on their location and size. Here, we present the case of an asymptomatic cardiac tumor that was discovered incidentally in a 66-year-old male patient during treatment for infective endocarditis of the mitral valve. Despite extensive cardiac imaging, the tumor could not be diagnosed before surgical intervention. Ultimately, the tumor was found on the epicardium of the right ventricle, close to the right coronary artery. It was completely resected. Histological analysis verified it as a cardiac cavernous hemangioma.
