Abstract
Invasive cardiac lipoma is a rare type of primary cardiac tumor that is composed of adipose tissue but infiltrating the adjacent structures. It is a benign tumor that can cause significant morbidity and mortality due to its size and location within the heart. We describe a giant invasive intracardiac lipoma across atrial wall extending to the ascending aorta and the superior vena cava. This review will provide an overview of invasive cardiac lipoma, including its clinical presentation, diagnosis, and management.

Abstract
Cardiac tumors are rare conditions, typically diagnosed on autopsy, but with the advancement of imaging techniques they are now encountered more frequently in clinical practice. Echocardiography is often the initial method of investigation for cardiac masses and provides a quick and valuable springboard for their characterization. While some cardiac masses can be readily identified by echocardiography alone, several require incorporation of multiple data points to reach diagnostic certainty. Herein, we will provide an overview of the main clinical, diagnostic, and therapeutic characteristics of cardiac masses within the framework of their location.

Liu W, Bu H. Strategies to rare primary cardiac lipomas in the left ventricle in a patient: case report. BMC Cardiovasc Disord 2022; 22:316. [PMID: 35840877 PMCID: PMC9288081 DOI: 10.1186/s12872-022-02748-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Accepted: 07/04/2022] [Indexed: 11/28/2022] Open
Abstract
Background Primary cardiac tumors are rare in all age groups and are usually benign. Symptoms are usually related to tumor size, location, invasiveness, number, and growth rate. While histologically benign, cardiac arrest may be caused by blocked inflow or outflow or malignant ventricular arrhythmia. Surgical resection of left ventricular tumors, especially those involving the outflow tract, is challenging. Case presentation Herein, we present a rare case of an asymptomatic, 39-year-old woman who was referred to our cardiovascular department for a huge left ventricular cardiac mass incidentally discovered during the physical examination. Images showed a huge mass that quasi-circular low-density focus with a clear boundary and regular shape in the left ventricular cavity and fortunately had no significant effect on the peripheral valves and hemodynamics. Conclusions This illustrative report highlights the exact surgical management of a cardiac tumor depends largely on the site and extent of the mass. Mechanical compromise and not the neoplastic potential should be considered. A conservative approach and follow-up regularly are advocated to ensure that the patient gets the best diagnosis and treatment, however, surgery is indicated only for severely symptomatic patients with hemodynamic compromise.

Abstract
Echocardiography is first-line examination of cardiac tumors. We report the case of a 25-year-old woman with a right atrial transmural invasive lipoma, and we review 58 published reports of primary cardiac invasive lipomas detected by echocardiography. We summarize the ultrasonographic characteristics and main sites of development, and examine the "invagination hypothesis". Echocardiography appears valuable for early detection, intraoperative monitoring, and postoperative follow-up of invasive cardiac lipomas.

Abstract
PURPOSE OF REVIEW Our purpose is to discuss the importance of multimodality imaging in the assessment of cardiac tumors and management. We have compiled a recent review of the scientific literature and embedded our clinical pathways and recommendations based on data and clinical experience. RECENT FINDINGS The use of contrast echocardiography in the assessment of cardiac masses has been shown to be helpful in distinguishing tumor from thrombus. Deformation imaging of cardiac tumors has been shown to differentiate better rhabdomyomas from fibromas in pediatric patients. Cardiac MRI (CMR) appears to be helpful in determining whether cardiac tumors are benign or malignant by identifying presence of infiltration, uptake of contrast in first pass perfusion and gadolinium enhancement. Patients with evidence of cardiac metastases by CMR show similar survival to stage IV cancer without cardiac metastases. In our institution, we use a standardized approach for the evaluation of cardiac masses, which includes multimodality imaging in the appropriate clinical context. The autotransplantation surgical technique has shown some promise in improving survival in patients with primary cardiac sarcomas. In our institution, we do not routinely recommend anticoagulation for "tumor-thrombus" in renal cell carcinoma due to risk of bleeding from primary tumor. Cardiac masses are often found incidentally, but sometimes can present with cardiovascular symptoms due to obstruction and valvular dysfunction, which may prompt imaging. It is important to determine whether the mass is a normal variant, imaging artifact, vegetation, thrombus, or tumor. Transthoracic echocardiography is ideally suited to be the initial imaging modality because of the portability, wide availability, lack of radiation, and relatively low cost. The gold standard cardiac imaging technique to distinguish tumor from thrombus is contrast enhanced CMR with prolonged inversion time. Advantages of CMR when compared to echocardiography regarding characterization of cardiac tumors are as follows: larger field of view, better spatial resolution, better tissue characterization, lack of attenuation, and ability to image at any prescribed plane. Primary and secondary cardiac tumors have particular characteristics in echocardiography and CMR. Imaging of cardiac tumors plays an important role in establishing a diagnosis and in planning management.

Abstract
Pericardial tumors are rare lesions that include a range of neoplastic conditions that may arise within the pericardium or metastasize to involve it secondarily. Understanding the spectrum of lesions that are included in the differential diagnosis of a pericardial mass-lesion is critical to making timely, accurate diagnoses and getting the appropriate therapy should one be necessary. This review summarizes the radiologic and pathologic findings of the most commonly encountered of these entities.

Abstract
Cardiac lipomas are rare and usually present as benign, encapsulated masses outside the heart; however, they can also be found within the atria. No single theory-including molecular genetic mutation-adequately explains why this occurs. Extensive career experience and broadened knowledge in embryology and cardiac physiology have helped us to develop a hypothesis based on invagination of extracardiac tumors. This report describes a vexing case of a giant right atrial lipoma, from 1985, in which the diagnosis was made incidentally during management of a patient's acute limb ischemia. In addition, we discuss the imaging and treatment of cardiac lipoma.

Abstract
Primary benign cardiac tumours are rarely found in clinical practice and are generally evaluated with echocardiography. However, with the increasing usage of helical multislice CT, the initial detection and evaluation of these masses may be made by the radiologist during routine daily practice for other indications. The echocardiographic, CT and cardiac MRI appearances of various benign cardiac tumours and masses are described and illustrated in this review.

Abstract
This imaging review describes the appearance of benign cardiac tumors on CT and MRI. Although rare, benign tumors outnumber their primary malignant counterparts three to one. Since mortality varies directly with invasion, identifying the neoplasm at an early stage helps focus treatment, especially in benign cases, which generally respond well to surgical resection. In adults and children, myxomas and rhabdomyomas, respectively, represent the most common benign tumors, which can be grouped into tissue-specific subtypes, such as rhabdomyomas, fibromas, lipomas, teratomas, etc. Besides their variable prevalence in particular age groups, these tumors also differ with regard to their gender predilection, location, and number. For example, myxomas appear predominantly in women and generally as a solitary mass in the left or right atrium, whereas rhabdomyomas present equally in boys and girls and chiefly as multiple masses in the ventricles. Despite their differences, however, both types share an association with heritable syndromes like the Carney complex for myxomas and tuberous sclerosis for rhabdomyomas. As with all cardiac tumors, echocardiographic findings usually suggest the initial diagnosis but cross-sectional imaging with CT and MRI can help resolve diagnostically challenging cases. For example, with its direct multiplanar capability, excellent contrast resolution, and large field of view, MRI permits a detailed examination of the entire mediastinum, helping to rule out an equivocal mass on echocardiography. Through dynamic techniques, MRI, in addition to morphologic characterization, can depict the pathophysiological effects of these tumors, for instance, with regard to myocardial contraction, valvular function, or blood flow.

Abstract
We report a rare case of massive left atrial lipoma occupying pericardial space. A 52-year-old male was admitted because of cardiomegaly of unknown etiology. Computed tomography showed a large epicardial mass located along the anterior surface of the heart, from the diaphragm level through the aortic arch level. The mass showed an attenuation value identical with that of subcutaneous adipose tissue and contained some areas with high density. The mass was not enhanced by contrast media. Histologic examination of the specimen obtained by percutaneous biopsy demonstrated mature adipose tissue. An encapsulated adipose mass weighing 620 g, which originated from the left atrium without any invasion to the pericardium, was completely excised. Microscopic examination revealed mature adipose tissue with partial necrosis, confirming the diagnosis of lipoma.

Abstract
Benign primary cardiac neoplasms are rare but may cause significant morbidity and mortality. However, they are usually treatable and can often be diagnosed with echocardiography, computed tomography (CT), or magnetic resonance (MR) imaging. Myxomas typically arise from the interatrial septum from a narrow base of attachment. Fibroelastomas are easily detected at echocardiography as small, mobile masses attached to valves by a short pedicle. Cardiac fibromas manifest as a large, noncontractile, solid mass in a ventricular wall at echocardiography and as a homogeneous mass with soft-tissue attenuation at CT. They are usually homogeneous and hypointense on T2-weighted MR images and isointense relative to muscle on T1-weighted images. Paragangliomas usually appear as large, echogenic left atrial masses at echocardiography and as circumscribed, heterogeneous masses with low attenuation at CT. These tumors are usually markedly hyperintense on T2-weighted MR images and iso- or hypointense relative to myocardium on T1-weighted images. Cardiac lipomas manifest at CT as homogeneous, low-attenuation masses in a cardiac chamber or in the pericardial space and demonstrate homogeneous increased signal intensity that decreases with fat-saturated sequences at T1-weighted MR imaging. Cardiac lymphangiomas manifest as cystic masses at echocardiography and typically demonstrate increased signal intensity at T1- and T2-weighted MR imaging. Familiarity with these imaging features and with the relative effectiveness of these modalities is essential for prompt diagnosis and effective treatment.

Abstract
An increase in the incidence of primary cardiac tumors has been reported since the development or enhancement of noninvasive imaging modalities. We identified 56 children with primary cardiac tumors. Forty-four (78%) children had rhabdomyomas, 6 (11%) fibromas, 1 (2%) pericardial teratoma, 1 (2%) epicardial lipoma, 1 (2%) multicystic hamartoma, and 3 (5%) unspecified tumors. The mean age at diagnosis was 19 +/- 35 months (median 4.7 months, range 0.03 to 204 months), excluding 12 patients who were given the diagnosis before birth. Among 27,640 patients assessed for cardiac disease, the incidence of tumors was 0.06% (1980 to 1984), 0.22% (1985 to 1989), and 0.32% (1990 to 1995). Diagnosis was made in 55 of 56 patients by echocardiography. Catheterization was performed in five patients and magnetic resonance imaging in nine. No tumor-related deaths occurred. Nine patients had surgery because of hemodynamically significant obstruction or arrhythmias. Partial or complete regression occurred in 24 (54%) of 44 patients with rhabdomyomas. Overall, the prognosis was excellent. Individualized surgery allowed early safe treatment of symptomatic tumors.
