Biatrial mass in heart resulting from colorectal cancer metastasis: Rarest case presentation
Dr. Sonal Tanwar, Dr. Naresh Sen, Dr. Ashok Jain
A 58-year-old male, chronic heavy smoker and a past history of rectal cancer (stage T3N1M0), treated with neo-adjuvant chemotherapy and radiation, followed by surgical resection with a low anterior resection, ileostomy formation and two subsequent cycles of adjuvant chemotherapy presented for further evaluation of worsening dyspnea, fatigue and lower extremity edema 3 years after follow-up. A CT scan of the chest revealed multiple pulmonary nodules, ascites, a 3 cm retroperitoneal lymph node and a mass in both atrium. 2D Echocardiogram revealed a mass in both right atrium and left atrium. A cardiac MRI showed the same Biatrial mass extending into the AV valve leaflet and the inferior vena cava to the level of the intrahepatic inferior vena cava. Chemotherapy was offered and followed by cardiac surgery to cardiac mass resection. Subsequently treatment modality was performed successfully and relieved dyspnea and edema. Colorectal cancers typically metastasize to the lymph nodes, liver or lungs. Metastasis to the heart is rare and although a few cases of cardiac metastases from colon cancer are described in the literature, cases of metastatic colorectal cancer to the heart are far fewer.
