Carcinoid tumors are malignancies of neuroendocrine tissue. Metastasis, most commonly to the liver, is associated with the carcinoid syndrome characterized by secretory symptoms and right-sided valvular heart disease. We report a case of previously unidentified pericardial metastasis, in the absence of any valvular disease, thus, reflecting an unusual cardiac complication of this tumor. A 50-year-old patient with histologically confirmed carcinoid syndrome underwent screening transthoracic echocardiography that demonstrated a large mass posterior to the interatrial septum. The location of this mass was confirmed by transesophageal echocardiography and magnetic resonance imaging to be entirely within the pericardial space without evidence of myocardial involvement. The mass was removed at thoracotomy and histology confirmed metastatic carcinoid disease. Although patients with carcinoid syndrome are at risk of cardiac valvular complications, and should be screened, this case demonstrates an unusual and previously unidentified site of metastatic disease.
