Cardiac hemangioma of the right atrium.
ABSTRACT Primary cardiac tumors are rare, with an incidence range between 0.001% and 0.030% at autopsy. Recent technical advances have facilitated diagnosis and surgical treatment of such lesions. Patients with a resectable tumor usually have a good prognosis, but patients with an unresectable tumor may have a poor prognosis. This report shows a case of right atrial hemangioma growing like an extracardiac mass, with cardiac tamponade the only clinical presentation.

ABSTRACT: Primary cardiac tumor is a rare disease, with an incidence ranging from 0.001 to 0.03%. Eighty percent of them are benign tumors, and among them 70% are myxomas, the others are: fibroelastoma, rhabdomyoma, fibroma, angioma and lipoma. Primary malignant tumors of heart are in 95% of cases sarcomas, the remaining 5% are lymphomas. Cardiac's metastases are more frequent than primary tumors. Diagnosis is made by echocardiography TAC and MRI. Whereas surgery is indicated in patients with benign tumors, or localised sarcomas, chemotherapy in those with widespread disease and radiotherapy and chemotherapy in lymphoma. Prognosis is excellent in benign cardiac tumor. Mean survival for sarcomas is 11 months, and lymphoma 5 years.Revue de Pneumologie Clinique 02/2010; 66(1):95-103. · 0.20 Impact Factor

ABSTRACT: Cardiac haemangiomas are rare benign primitive tumors. We are reporting the case of a 67-year-old woman presenting with a haemangioma of the right atrium. This tumor was discovered by echocardiography because of cerebral strokes. The magnetic resonance imaging determined the characteristics of the tumor. It was completely resected through a right atrial approach. This was a round mobile mass, pediculed and implanted at the inferior area of the interatrial septum. The histopathological analysis revealed a cavernous haemangioma.Annales de cardiologie et d'angeiologie 01/2011; 60(3):173-5. · 0.21 Impact Factor

Primary cardiac tumors are rare, with an incidence range between 0.001% and 0.030% at autopsy. Recent
technical advances have facilitated diagnosis and surgical treatment of such lesions. Patients with a
resectable tumor usually have a good prognosis, but patients with an unresectable tumor may have a
poor prognosis. This report shows a case of right atrial hemangioma growing like an extracardiac
mass, with cardiac tamponade the only clinical presentation.
Cardiac hemangiomas are exceptionally rare with only a
1–2% incidence in all detected benign heart neoplasms.1
Tumors with extracardiac extension are rarely symptomatic
and found by chance.2This report shows a case of right atrial
hemangioma growing like an extracardiac mass, with
cardiac tamponade as the only clinical presentation.
A white 30-year-old male was seen at the University Hospital
in January 2002 with cough and chest pain for the past 5
days. At physical examination, it was found arterial blood
pressure of 100 ? 80 mmHg, heart rate of 120 bpm, mild
jugular ingurgitation, and regular cardiac rhythm without
Chest radiography showed increased heart size. Electro-
cardiogram showed a low voltage complex and sinusal
large pericardial effusion and signs of cardiac tamponade.
Closed pericardiocentesis showed bloody effusion without
neoplastic cells at cytopathological examination. Biochemi-
cal tests were normal. The patient was discharged after
clinical improvement. Four months later, he was rehospita-
lized because of severe dyspnea and reported a 12 kg body
weight loss. Echodopplercardiogram revealed a large mass
filling the right atrium, right ventricle and pericardial
space, restricting the ventricle filling (Figure 1A). A chest
computed tomography (CT) showed a hypodense hetero-
geneous mass, measuring 13 ? 11 ? 12 cm, with outer
lining well defined by the pericardium (Figure 1B).
Surgical approach was unable to completely remove the
tumor. Histological exam showed a benign vascular neoplasia
with hyalinized stroma and deposits of hemosiderin, without
architectural disarrangement, being defined as a combi-
nation of cavernous and capillary types (Figure 2A and B).
Interferon therapy was initiated without success. One
month later, the patient had sudden cardiac death.
Cardiac hemangiomas grow from the benign proliferation of
endothelial cells and may occur in any part of the heart,
being more common in the right heart chambers.3–6Histo-
logically they are classified into three types: tumors com-
posed of multiple, dilated, thin walled vessels (cavernous
type), smaller capillary-like vessels (capillary type), and
dysplastic arteries and veins (arteriovenous type). A combi-
nation of cavernous and capillary types are more frequently
Most cardiac hemangiomas are asymptomatic, discovered
incidentally by echocardiography, CT, MRI or at autopsy.1,5
Symptomatic patients present arrhythmias, pericardial effu-
sions, congestive heart failure, right ventricular outflow
tract obstruction, embolic episodes, myocardial ischemia,
and sudden death. Although echocardiography may provide

the information needed for surgical treatment, cardiac
catheterization and MRI are more precise for diagnosis.7
Differential diagnosis of mass lesions in the heart include
thrombi, myxoma, lipoma, fibroma, cyst, and other malig-
nant tumors such as angiosarcoma. The outcomes of
cardiac hemangioma are unpredictable. Patients with an
unresectable tumor may have a poor prognosis because of
ventricular tachycardia, sudden death, local progression,
or systemic dissemination of the malignant tumor.8
