“…Lipomas show the same signal intensity as subcutaneous fat in all CMR sequences. They present as homogeneous hyperintense compared with myocardium on T1WI and the characteristic complete signal loss of the mass is seen in the fat suppression sequence [ 118 ]. On T2WI, they tend to show hyperintensity relative to the myocardium.…”

“…It is worth noting that because of the chemical shift effect, the black boundary sign in the cine sequence is helpful for the diagnosis of small lipomas. What is more, CMR can sensitively detect the myocardial infiltration of lipoma, which provides imaging evidence for treatment planning [ 118 ].…”

Primary cardiac tumors (PCTs) are rare, with benign PCTs being relatively common in approximately 75% of all PCTs. Benign PCTs are usually asymptomatic, and they are found incidentally by imaging. Even if patients present with symptoms, they are usually nonspecific. Before the application of imaging modalities to the heart, our understanding of these tumors is limited to case reports and autopsy studies. The advent and improvement of various imaging technologies have enabled the non-invasive evaluation of benign PCTs. Although echocardiography is the most commonly used imaging examination, it is not the best method to describe the histological characteristics of tumors. At present, cardiac magnetic resonance (CMR) and cardiac computed tomography (CCT) are often used to assess benign PCTs providing detailed information on anatomical and tissue features. In fact, each imaging modality has its own advantages and disadvantages, multimodality imaging uses two or more imaging types to provide valuable complementary information. With the widespread use of multimodality imaging, these techniques play an indispensable role in the management of patients with benign PCTs by providing useful diagnostic and prognostic information to guide treatment. This article reviews the multimodality imaging characterizations of common benign PCTs.

“…This can be obtained with a low-carbohydrate, high-fat diet and with the administration of 50 Units/Kg of body weight of unfractioned heparin before the injection of 18 FDG. 111,112 Other tumors, as neuroendocrine tumors and paragangliomas, require the use of different tracings as 68 Ga-DOTA-peptide or others. 113,114 For ventricular tumors, mostly if they are in close relationship with a coronary artery, a coronary angiography or a CT scan with cardiac synchronization and 3D reconstruction may be considered to better define both the size of the mass and its relationship with the neighboring structures; CT and MRI may also aid in the tissue characterization.…”

“…Rhabdomyomas, rhabdomyosarcomas, and leiomyosarcomas usually show a homogenous echogenicity; hyperechogenic and hyperlucent central areas may represent foci of necrosis or of calcification. Lipomas may show different aspects, from hypo‐ to hyperechoic, but are usually homogenous 67–69 . Fibromas show usually an increased echogenicity compared to the normal myocardium 70–72 .…”

Cardiac tumors may be primary (either benign or malignant) or secondary (malignant) and are first detected by echocardiography in most cases. The cardiologist often challenges their identification, the differential diagnosis and the best therapeutic approach. Malignant tumors have usually a poor prognosis, which may be significantly improved by appropriate and timely therapies. The echocardiographic aspects of benign and malignant cardiac tumors described in this article, along with a clinical evaluation may orient the differential diagnosis and aid in choosing the further steps useful to define the nature of the mass,

“…On CT scans, lipomas are homogeneous fatty lesions with well-identified borders and attenuation values ranging between −30 and −100 Hounsfield units (HU), with no contrast-enhanced components. Compared with lipomas, liposarcomas are heterogeneous malignant fatty tumors, with a mean attenuation value greater than −30 HU, due to soft tissue and fibrous strands alternating with areas of fat [ 5 , 8 , 9 ]. On MRI, lipomas are homogenous lesions with signal intensity typical of fat tissue – hyperintense on both T1- and T2-weighted images, with the absence of internal septa or nodules and complete fat suppression on selective fat-suppressed images and showing little to no contrast enhancement.…”

Patient: Female, 64-year-old Final Diagnosis: Intrapericardial lipoma Symptoms: No symptoms Medication:— Clinical Procedure: — Specialty: Cardiology Objective: Rare disease Background: Primary cardiac and pericardial neoplasms are rare and may be found incidentally on echocardiography. We present a case of a 5-year imaging follow-up in a patient with a large posterior pericardial lipoma diagnosed by magnetic resonance imaging of the mediastinum. Case Report: A 64-year-old woman was admitted to the Department of Cardiology for detailed assessment due to an intrapericardial mass revealed on transthoracic echocardiography in an outpatient setting. Computed tomography revealed a capsulated posterior intrapericardial homogenous mass of fat density. There was no enhancement of the lesion with contrast agent administration. Ultimately, magnetic resonance imaging confirmed the benign nature of the tumor, leading to the intrapericardial mass being classified as a lipoma. Due to the clinical features of the lesion – the preserved intracardiac flow and the asymptomatic course of the disease – conservative treatment was appropriate for this patient. A 5-year imaging follow-up was uneventful, the patient remained asymptomatic, a mild tumor growth was identified by computed tomography, and there was still no recommendation for surgery. Conclusions: This case has shown that although echocardiography and computed tomography imaging can identify posterior intrapericardial tumors, magnetic resonance imaging can identify diagnostic features and support the benign nature of a tumor that may not be amenable to surgical removal.
