“…Because the tumor tends to occur in the right atrium and involve the pericardium, patients usually present with right-sided heart failure or tamponade (1,5,6) as fever and weight loss (8). Pericardiocentesis yields bloody fluid that often does not contain malignant cells, even when the tumor has invaded the pericardium (9)(10)(11)(12)(13)(14). Prognosis is poor, which may be due in part to the delay in diagnosis (15).…”

“…At gross examination, the tumors are hemorrhagic, necrotic, and often adherent to the pericardium (Fig 1) (1). CT often shows a low-attenuation right atrial mass, which may be irregular or nodular (21) and usually arises from the right atrial free wall (13,14,22). Areas of central necrosis in communication with a cardiac chamber have been seen at both CT and MR imaging (23,24).…”

Primary cardiac malignancies are rare tumors that are difficult to diagnose clinically. Different primary cardiac malignancies may have different clinical, morphologic, and radiologic features and intracardiac locations. Angiosarcoma is the most common primary cardiac malignancy. It tends to occur in the right atrium and involve the pericardium. Because of its tendency to hemorrhage, angiosarcoma often demonstrates areas of increased signal intensity with T1-weighted sequences. Undifferentiated sarcomas typically occur in the left atrium and have variable epidemiologic and radiologic features. Rhabdomyosarcoma is the most common primary cardiac malignancy in children and is more likely than other primary cardiac sarcomas to involve the valves. Primary cardiac osteogenic sarcoma almost always occurs in the left atrium and frequently demonstrates calcification. Certain features (eg, broad base of attachment, origin at a site other than the atrial septum) help differentiate this tumor from left atrial myxoma. Leiomyosarcoma favors the left atrium and tends to invade the pulmonary veins and mitral valve. Fibrosarcoma also tends to occur in the left atrium and is often necrotic. Liposarcoma is very rare and usually manifests as a large, infiltrating mass. Foci of macroscopic fat are occasionally seen. Primary cardiac lymphoma occurs more commonly in immunocompromised patients, frequently involves the pericardium, and, unlike other primary cardiac malignancies, may respond to chemotherapy. The advent of cross-sectional imaging has allowed earlier detection of primary cardiac malignancies as well as more accurate diagnosis and characterization.

“…Coronary artery fistulas are uncommon and, typically, congenital, although rare reports of acquired arterio- venous malformations have implicated tumor, thrombus, injury, or ischemia [1][2][3][4][5][6][7][8]. While our patient had previously had a mediastinal tumor, no abnormal vascularity was noted at the time of resection, and the patient had survived 15 years without evidence of recurrent malignant disease, thus making tumor neovascularization unlikely.…”

“…More than 90% of these drain into the right side of the heart, with approximately 15% draining into the pulmonary circulation [1]. Acquired coronary artery malformations are uncommon, and have been reported in association with myocardial ischemia [2], mural thrombi [3][4], penetrating trauma [5][6], and intracardiac tumors [7][8]. In these cases, acquired fistulas have developed from coronary artery to coronary artery, or as arteriocameral fistulas.…”

“…In one report [6], a right coronary artery supplied mass first prediagnosed as myxoma diagnosed as angiosarcoma after pathological examination. The other report [7] described the transesophageal images of a prolapsing angiosarcoma with polycystic appearance previously misinterpreted as a right atrial myxoma.…”
