case_images: MRI demonstrated a large mass in the right ventricular cavity. The tumor was elliptic with smooth outer margin and was approximately 29 mm x 23 mm x 30 mm in size, resulting in severe stenosis of the right ventricular outflow tract.

case_images: The CMRI showed a slightly high signal on T1-weighted images, a high signal on T2-weighted images, a smooth outer edge approximately 29 mm x 23 mm x 30 mm in size, and RVOT stenosis (Figure 1).
case_images: The tumor was located in the outflow tract of the right ventricle, with smooth surface and red cystic mass.

case_images: Intraoperative heart enlargement was observed mainly in the right side of the heart, and a purplish red cystic tumor, with the size of approximately 30 mm x 30 mm, was observed in the RVOT, with complete envelope, no obvious adhesion to surrounding tissues (Figure 2).
case_images: A cystic mass with an intact envelope (A), histopathologic and immuohistochemical stainin examination confirms the diagnosis of cardiac hemolymphangioma (H&E, x100, B,C).

case_images: The results of immunohistochemical tests showed the tumor cell markers CD31+ and CD34+; therefore, the patient was pathologically diagnosed with hemangilymphangioma (Figure 3).
