A giant cavernous hemangioma of the heart

Unexpected diagnosis: large hemangioma in the interatrial septum

BACKGROUND

Cardiac hemangiomas are very uncommon benign primary tumors. They are usually located preferentially in the right atrium and their location in the interatrial septum is extremely rare.

CASE PRESENTATION

We report the case of a 41-year-old patient who was admitted due to a stroke. The transthoracic echocardiogram revealed a large mass in the right atrium adhered to the interatrial septum. Suspecting an atrial myxoma, surgical intervention was performed confirming that the mass extended within the thickness of the interatrial septum, protruding into the right atrial cavity. The histologic report confirmed a hemangioma.

CONCLUSIONS

Cardiac hemangiomas are rare primary tumors and are usually misdiagnosed as other cardiac tumors. Histopathological examination is essential for a definitive diagnosis.

MR imaging of primary benign cardiac tumors in the pediatric population

Primary cardiac tumors are rare in all ages, especially in children, with a reported prevalence range of 0.0017-0.28% in autopsy series. Due to their rarity, the diagnostic and therapeutic pathways reserved to them are usually described by single case reports, leading to the point where a common diagnostic protocol is imperative to obtain a differential diagnosis. The first diagnostic approach is done with transthoracic echocardiogram (TTE), due to its wide availability, low cost, absence of ionizing radiations and non-invasiveness. Several tumors are discovered incidentally and, in many cases, TTE is helpful to determine location, size and anatomical features, playing a key role in the differential diagnosis. In the last few years, cardiac magnetic resonance imaging (CMR) has had an increased role in the diagnostic pathway of pediatric cardiac masses, due to its high accuracy in characterizing mass tissue properties (especially for soft tissue), and in detecting tumor size, extent, pericardial/pleural effusion, leading to the correct diagnosis, treatment and follow-up. Therefore, nowadays, several consensus statements consider CMR as a leading imaging technique, thanks to its non-invasive tissue characterization, without the use of ionizing radiation, in an unrestricted field of view. As suggested by the most recent literature, the pediatric protocol is not so different from the adult one, adapted to the size and cardiac frequency of the patient, sometimes requiring special conditions such as free-breathing sequences and/or sedation or general anesthesia in non-cooperating patients.

Patient with myelodysplastic syndrome presented with recurrent pericardial effusion diagnosed as epicardial hemangioma; Case report of a rare diagnosis with rare presentation

Primary cardiac tumors are extremely rare and cardiac hemangiomas comprise less than 3% of them. Presentation of such disease with recurrent pericardial effusion is even rarer. Our patient is known case of myelodysplastic syndrome and up to our knowledge there are no reported case in which cardiac hemangioma was diagnosed in a patient with myelodysplastic syndrome. This 64 years male patient presented to our department with recurrent pericardial effusion, diagnosis was a query after extensive work he was found to suffer from a cardiac tumor based on the pulmonary artery and right ventricle. We performed surgery for him on cardiopulmonary bypass and did complete resection of the mass for him and result of biopsy showed mixed hemangioma. Recurrent pericardial effusion is most commonly a sign of a malignancy. Even with advancement of medical technology diagnoses of cardiac hemangiomas are still difficult. Treatment and definitive diagnosis is still complete surgical resection and histopathological examination.

A Giant Cardiac Hemangioma Encroaching on the Right Coronary Artery

The cardiac hemangioma is a relatively rare cardiac tumor. It can occur in different locations in the heart. We describe a patient with a giant cardiac hemangioma encroaching on the right coronary artery who underwent a successful surgical resection. Complete resection of the tumor was achieved without damaging the function of the right coronary artery. Nonetheless, meticulous follow-up is required as recurrence is possible.

Diagnostic mystery-a rare right ventricular cardiac hemangioma: a case report

BACKGROUND

Cardiac hemangiomas are rare in all kinds of benign cardiac tumors. Although cardiac hemangiomas affect all ages and may occur anywhere within the heart, right ventricular hemangiomas are extremely uncommon.

CASE PRESENTATION

We report a 56-year-old woman presented with chest tightness and breath shortness for 3 months. Transthoracic echocardiography and coronary computed tomography angiography showed a mass located adjacent to the apex of the right ventricle but both failed to figure out where the mass originated from, remaining a diagnostic mystery preoperatively. The mass was removed successfully and the histopathological examination confirmed it was hemangioma.

CONCLUSIONS

Cardiac magnetic resonance should be the ultimate diagnostic tool of cardiac tumors. Surgical removal, associated with a low recurrence rate and long-term survival benefits, should be the first choice of therapy for cardiac hemangiomas.

Right atrial cavernous hemangioma

Benign cardiac hemangiomas are rare tumors that may present in or out side of the heart, epicardium being the most common site. Echocardiography is the method of choice in diagnosing cardiac masses and though 3D TEE may seem to add exact information about the location, the time constraint in doing a comprehensive examination along with 3D rendering inside operation room may become an hindrance.

A Giant Cardiac Cavernous Hemangioma Involving the Left Atrial Roof in an Elderly Woman

Cardiac tumors are relatively rare, with primary hemangiomas being a particularly rare benign neoplasm. Herein, we report a case of a symptomatic cardiac tumor detected via echocardiography in an 82-year-old woman. Although we performed advanced imaging examinations for her heart, we could not diagnose the tumor before surgery. Eventually, a tumor involving the left atrial roof was detected, and it was completely resected to relieve her symptoms and establish a precise diagnosis. Histopathological examination indicated a cardiac cavernous hemangioma. The patient exhibited an uneventful recovery without any complications.

Debulking surgery for venous hemangioma arising from the epicardium: report of a case

BACKGROUND

Cardiac hemangiomas are rare benign vascular tumors that can occur in any cardiac layer: endocardium, myocardium, or epicardium. Histologically, cardiac hemangiomas may be classified as capillary, cavernous, or arteriovenous; venous hemangiomas are extremely rare.

CASE PRESENTATION

A 46-year-old man reported experiencing precordial discomfort. Computed tomography revealed a massive tumor adjacent to the right ventricle. The right coronary artery was found to be located at the center of the tumor. Cardiovascular angiography showed that the artery was completely encased by the tumor without any obstruction and that the right ventricular lumen was compressed by the tumor. Surgical debulking of the tumor was performed under cardiopulmonary bypass, and the frozen section led to a diagnosis of benign hemangioma. The tumor was debulked as much as possible until the right coronary artery appeared. For decompression of the heart, the pericardium was left open to the thoracic cavity and unsutured. Histopathologic examination revealed a diagnosis of epicardial venous hemangioma.

CONCLUSIONS

Cardiac hemangioma should be included in the differential diagnosis of mediastinal tumor in reference to the location and flow of the coronary artery. Surgical resection, or at least tumor debulking, is required to confirm the diagnosis and prevent further complications and has a favorable clinical outcome.

Resection of a giant cardiac hemangioma

We present a case of a 61-year-old female who underwent excision of the mass within left atrial appendage. She underwent cardiac surgery due to cardiac tumor. The tumor was measured 6 cm, and it was completely resected. After surgery, pathological examination diagnosed endocardiac-based cardiac hemangioma. The post operative course was uneventful and the patient discharged on the 18th postoperative day.

Giant tumor of the right atrium in infancy

Cardiac hemangiomas can occur at any age, but they are extremely rare when they occur early after birth. We describe the case of a 5-month-old infant who had a giant right atrial capillary hemangioma associated with massive pericardial effusion. The tumor was incidentally diagnosed during routine clinical follow-up. The hemangioma was removed successfully under cardiopulmonary bypass, and the patient's postoperative course was uneventful. The occurrence of giant capillary hemangioma in infancy represents an unusual event in the relevant literature. Herein, we discuss the clinical features and surgical management of this rare primary tumor of infancy.
