Surgical treatment of a giant cardiac hemangioma in right atrium with pulmonary vein compression.

BACKGROUND

Cardiac hemangiomas (CHs) are rare benign vascular tumors, which can develop in any cardiac chamber or layer. Large right atrial hemangioma causing compression of the pulmonary vein is exceedingly rare and complete surgical resection may be needed.

CASE PRESENTATION: A 52-year-old asymptomatic male was incidentally found to have a cardiac mass during a routine health examination. A well-defined, low-metabolism mass compressing the pulmonary vein was confirmed by PET-CT. The tumor was completely resected, and the histopathology and immunohistochemistry confirmed the diagnosis of cavernous hemangioma. The patient recovered uneventfully and was discharged in stable condition.

CONCLUSIONS

Although rare, cardiac hemangiomas should be considered in the differential diagnosis of intracardiac masses. Complete surgical resection is feasible and leads to favorable outcomes, even in cases with complex anatomical relationships.
