Isolated Cardiac Metastasis From Sacral Chordoma

概要

A 64-year-old woman presented with right heart failure caused by a cardiac tumor centered in the free wall of the right ventricle, accompanied by pericardial effusion. A match between the biopsy specimen and tissue removed 4 years earlier resulted in the diagnosis of a cardiac metastasis from a chordoma. Immunohistochemical staining was also useful in establishing the diagnosis. To alleviate the right ventricular outflow obstruction, a palliative operation was planned, resecting the tumor and performing a right ventriculoplasty, which was cancelled due to the extent of infiltration of tumor, and instead a right atrium to pulmonary artery shunt was attempted using a vascular prosthesis, only to fail due to an inability to maintain blood flow through the prosthesis. Presently there are no definitive treatment options available, and some palliative chemotherapy is being performed. Single cardiac metastases from a chordoma are extremely rare.
