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.

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).
The tumor was located in the outflow tract of the right ventricle, with smooth surface and red cystic mass.

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).
A cystic mass with an intact envelope (A), histopathologic and immuohistochemical stainin examination confirms the diagnosis of cardiac hemolymphangioma (H&E, x100, B,C).

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