Cardiac Hemangioma: A Comprehensive Analysis of 200 Cases

Epicardial cardiac cavernous Haemangioma-a case report

Background

Cardiac haemangiomas are exceptionally rare. They are usually solitary growths. Cardiac haemangiomas can be classified as capillary, cavernous, or arteriovenous in nature. They can occur in any chambers of the heart, but are predominantly found at the intramural or endocardial layers.

Case presentation

This is a rare case of a cardiac haemangioma located on the epicardium of a 52-year-old male patient. The patient complained of 1-year duration of chest tightness and shortness of breath. The haemangioma was removed successfully. For symptomatic lesions, surgical removal remains the preferred treatment.

Conclusion

The pathological diagnosis was primary cardiac cavernous haemangioma. In this case, the haemangioma was successfully resected with invasive surgery. No recurrence was detected on follow up.

Enlarging left atrial haemangioma in a patient with Cowden syndrome

A 53-year-old female patient known to have Cowden disease (PTEN mutation positive) was found to have a mass at the left atrium on a CT coronary angiography performed as part of a preoperative workup for an unrelated surgery. Further radiological characterisation of the lesion was achieved using MRI and positron emission tomography. Interval growth prompted surgical excision; however, surgery was expedited after the patient presented with haemopericardium and cardiac tamponade. The patient was discharged home 8 days postoperatively, and no intraoperative or postoperative complications were encountered. A diagnosis of cavernous haemangioma was made on histology.

Left atrial cavernous haemangioma presenting with cardiac tamponade in a patient with Cowden syndrome

Cowden syndrome (CS) is a rare disorder characterised by multiple non-cancerous, tumour-like growths called hamartomas. The syndrome is associated with the development of cancer of the breast, endometrium, kidneys, skin and rarely the brain. We report a rare case of symptomatic cardiac haemangioma in a patient with CS. A 54-year-old woman with CS presented with dyspnoea and orthopnoea in the setting of cardiac tamponade. Echocardiography revealed a large haemopericardium and tamponade physiology, secondary to a pericardial mass. The patient underwent urgent cardiopulmonary bypass with removal of the mass. Histopathology confirmed a benign cavernous haemangioma. We postulate that tumours involving the heart/pericardium may be an additional manifestation of CS. This case further highlights the necessity to consider pericardial/cardiac manifestations in patients with hamartomatous syndromes who present with cardiorespiratory symptoms, so that opportunistic investigation and treatment may be instituted.

Occam's razor versus Hickam's dictum: two very rare tumours in one single patient

Occam's razor, the principle that a single explanation is the most likely in medicine, assumes that when a patient has multiple symptoms the clinician seeks a single diagnosis rather than diagnosing multiple and different ones. However, as proposed by Hickam’s dictum, sometimes rare different diseases occurred in only one patient.

We present a patient with a simultaneous diagnosis of two rare tumours, a cardiac hemangioma (primary cardiac tumour, often misdiagnosed as myxoma) and an appendiceal mucocele (a lesion of the appendix that can be neoplastic or not).

A 71-year-old male presented with anorexia, asthenia, fever and weight loss for about one month. During the etiological investigation, a cardiac mass and an appendiceal lesion were detected and both lesions required surgical intervention. Cardiac and abdominal surgeries were uneventful and full recovery was achieved. The histological examination showed a cardiac hemangioma and a neoplastic appendiceal mucocele.

Successful treatment of cardiac haemangiomas with oral propranolol: a case series of two patients

BACKGROUND

Cardiac haemangiomas are extremely rare tumours with equivocal surgical outcomes. Haemangiomas appearing on other sites of the body have been successfully treated with oral propranolol. To the best of our knowledge, such treatment has not been tried to date for cardiac location of haemangiomas.

CASE SUMMARY

We report two cases of neonatal cardiac haemangiomas, and we describe their presentation and characteristics, as well as how these were successfully treated with oral propranolol, with complete regression of the tumours within the 1st year of life.

DISCUSSION

Despite the rarity of cardiac haemangiomas, their presentation and complications could be dramatic with side-effects spanning from intracardiac space occupying phenomena to Kasabach-Merritt syndrome. Propranolol therapy, having been established for long now in the treatment of skin haemangiomas, should also be considered in cases of cardiac haemangiomas, particularly in the neonatal and infantile population.

Cardiac venous malformation in a teenager

We present the case of a 17-year-old boy with a cardiac venous malformation. This case highlights the diagnostic challenges of such tumours and demonstrates the potential efficacy of a watch-and-wait management approach.

Hemangioma of the Atherosclerotic Changed Aortic Valve

The incidence of heart valve hemangioma is very low and is mostly observed in the mitral and tricuspid valve. In 2006, two cases of aortic valve hemangioma were reported for the first time, including one with calcifying aortic valve stenosis. We now present a case of aortic valve hemangioma in a patient suffering from aortic valve insufficiency combined with atherosclerotic thickening.

Neonatal Cardiac Arrest From Left Ventricular Cardiac Hemangioma: A Surprising Presentation

Cardiac hemangioma is rare, even more when leading to a cardiovascular collapse in a seemingly healthy newborn. A 6-day-old neonate had a tamponade caused by a basolateral hemangioma of the left ventricle. Partial surgical resection was performed. A congenital lobular capillary hemangioma was diagnosed upon histologic examination. The patient recovered completely and shows normal development at the 12-month follow-up.

Atrial Hemangioma: A Case Report and Review of the Literature

A primary cardiac tumor is a rare clinical entity which was reported an incidence of 0.03% in previous autopsy series. 75% cardiac tumors are cardiac myxoma and cardiac hemangiomas constitute only 1–2% of primary cardiac tumors. With the development of modern medical imaging technology and the enhancement of people’s health awareness, more and more asymptomatic cardiac hemangiomas were found and confirmed eventually. Here, we described a case of a 71-year-old man, who was hospitalized with intermittent palpitation for 1 year and a large mass of the heart was removed successfully via sternotomy which was confirmed as atrial hemangioma by postoperative histopathology. Furthermore, a comprehensive review of atrial hemangioma was conducted to date and a few recommendations for the diagnosis and treatment of this uncommon disorder were provided for clinicians.

Right atrium hemangioma in patient with history of mixed-thrombus surgery

Primary cardiac neoplasms are rare, cardiac hemangiomas are even rarer, and a mixed thrombus followed by a primary cardiac hemangioma is exceptionally rare epidemiology. Here, we report the case of a man with a right atrium mixed-thrombus surgical history who went on to develop a cardiac hemangioma.

Infantile cardiac hemangioma causing right ventricular inflow obstruction

Cardiac hemangiomas are extremely rare tumors, especially in infants. We present the case of a 4-month-old girl who developed cyanosis due to a large right atrial tumor causing right ventricular inflow obstruction. The patient underwent emergency surgery for tumor resection and recovered uneventfully. Pathological examination confirmed the diagnosis of a combined capillary and cavernous type hemangioma.

Giant congenital right atrial epithelioid-capillary hemangioma with prolonged QT interval: Case report and practical surgical treatment strategy for primary cardiac tumors in children based on 25-year review of 299 cases

Cardiac hemangioma is very rare and accounts for 2%-3% of the primary cardiac tumors. Cardiac epitheloid-capillary hemangioma has not been reported in the pediatric population so far. We report the fatal outcome of a preterm neonate with a huge congenital right atrial epitheloid-capillary hemangioma and elevated serum alpha-fetoprotein, associated with prolonged QT interval. We describe the echocardiographic, computed tomographic (CT) imaging, microscopic and immunohistochemical features of the tumor. Complete resection of the tumor was done at operation necessitating extensive reconstruction of atrial walls. Intramural infiltration of this tumor into the surrounding myocardial walls is a challenging characteristic of cardiac hemangioma. The temptation to complete resection should be avoided in the setting of extensive intramural infiltration and entrapment of the tumoral cells into atrial walls, particularly in a preterm neonate. None of the current classifications for hemangioma was inclusive of our case. Based on a concise literature review of nine published classification systems from 1996 to 2017 , we discuss the shortcomings of the current classifications for hemangioma. We also performed a 25-year-review of 299 cases of primary cardiac tumors in neonates and children, from 1993 to May 2018. We suggest a stepwise surgical treatment strategy according to the characteristics of the patient and of the tumor, based on this review. The stepwise strategy includes watchful observation, partial resection, complete resection and cardiac transplantation.

Left ventricular cardiac hemangioma in a patient with chronic heart failure

Cardiac hemangiomas are rare benign tumors. Here, we report the case of a man in his 30s who had a cardiac hemangioma with no symptoms. He was being treated with β-blockers for chronic heart failure with hypertensive heart disease at Osaka Minato Central Hospital. Routine echocardiography revealed a mobile spherical mass in the left ventricle that had not been detected on echocardiography performed 4 months previously. Subsequently, the tumor was excised to prevent potential embolic events and was pathologically diagnosed as a cardiac hemangioma. This case demonstrates the relatively rapid progress of a cardiac hemangioma regardless of β-blocker administration, which is occasionally used for the treatment of hemangiomas. The efficacy of β-blockers in treating cardiac hemangiomas may vary according to the type of β-blocker. Echocardiography is useful in screening and follow-up of cardiac hemangiomas; however, additional imaging modalities are needed for differential diagnosis.

Lymphocyte-rich capillary-cavernous hemangioma of the mitral valve: a case report and review of the literature

Valvular hemangioma incidence is extremely low. In this report, we describe a 62-year-old man who presented with mild edema of the lower limbs. An echocardiogram revealed an incidental 1.3-cm diameter mass on the anterior mitral valve leaflet for which he underwent surgical resection and mitral valve replacement. Histopathological examination showed a lymphocyte-rich capillary-cavernous hemangioma. The exuberant lymphoid stroma is unusual for hemangioma and represents an undescribed pattern of cardiac hemangioma. Including the present report, only 13 cases of mitral valve hemangioma have been reported to date. Most patients are adult. Mitral hemangioma originates in the atrial aspect of the valve and involves more commonly the anterior leaflet. The average maximum diameter of the lesion is 1.7 (S.D.=0.75) cm. Pure cavernous hemangioma is the predominant type of mitral hemangioma. Most of them are described as pedunculated or polypoid. Surgical excision appears to be curative. Recurrences have not been reported. Lymphocyte-rich cardiac hemangioma represents a peculiar type of hemangioma which should be included in the differential diagnosis of other vascular lesions.

Case report: a rare case of pedunculated LV hemangioma evaluated by 3D echocardiography and compared with myxoma

We report a case of a pedunculated, hypermobile LV mass, which was evaluated by 2D as well 3D transthoracic echocardiography (TTE). A presumptive diagnosis of cardiac hemangioma was made based on 3D cropped images. This was later confirmed on histopathology as well as histochemical staining.

Primary Cardiac Osteosarcoma

BACKGROUND

Primary cardiac osteosarcoma is extremely rare. There is no cohort study on such tumours to date. The aim of this study is to investigate the clinical characteristics and outcome patterns of such tumours.

METHODS

A thorough literature review was performed, and all relevant clinical items were collected. A total of 53 cases of primary cardiac osteosarcoma were enrolled in this study, including 25 males and 28 females.

RESULTS

The age at diagnosis ranged from 14 to 77 years with a mean age of 43.6 years. The clinical manifestations, imaging features, and laboratory tests of the primary cardiac osteosarcomas were similar to other types of primary cardiac tumours. Sex, tumour size and adjunctive chemo-radiotherapy were found to affect the overall survival pattern.

CONCLUSIONS

The present study may provide an effective consultation for the diagnosis and treatment of this tumour.
