Key result
Surgical resection successfully resolves a rare left atrial capillary hemangioma mimicking myxoma.
Why the study?
Cardiac hemangioma is a rare primary cardiac tumor that can be misdiagnosed as a myxoma, especially when arising from the left atrial wall.
Case Report (n=1)
Cardiac hemangiomas can arise from the left atrial wall and mimic myxomas, highlighting the importance of pathological confirmation after surgical resection.
Rare hemangiomas may mimic myxomas on imaging; adds to sparse case literature but leaves optimal management open.
Hemangioma of the heart, presenting as a primary cardiac tumor is extremely rare; it accounts for approximately 2% of all primary resected heart tumors. In our patient, the tumor was located in the orifice of the right lower pulmonary vein. Few cases of cardiac hemangiomas have been reported to arise from the left atrial (LA) wall. Left atrial hemangiomas, especially those attached to the LA wall, may be erroneously diagnosed as myxomas. Cardiac hemangioma is a rare disease; furthermore, a tumor arising from the LA wall and misconceived as a myxoma is extremely rare. We removed a mass misdiagnosed as a myxoma; it was pathologically confirmed to be a cardiac capillary hemangioma. Therefore, we report a rare case of a cardiac hemangioma misconceived as a myxoma; the tumor was removed successfully.

Hong et al. (2014) conducted a case report in Cardiac hemangioma (n=1). Surgical removal was evaluated on Pathological confirmation and surgical outcome. Surgical removal of a left atrial mass misdiagnosed as a myxoma was successfully performed and pathologically confirmed to be a rare cardiac capillary hemangioma.
