“…As shown in case 1, hypodense lesions located within the pulmonary arteries compatible with intra-arterial hydatid cysts should be differentiated from other intraluminal filling defects such as pulmonary thromboembolism and pulmonary arterial tumors [7]. The differential diagnosis of cardiac tumors must include benign lesions such as thrombus, hemangioma, myxoma and fibroma, and malignant tumors such as myxosarcoma, angiosarcoma, fibrosarcoma, and neurofibrosarcoma [10,11]. In the presented cases lack of symptoms of malignancy ± with the exception of respiratory failure ± generally good clinical condition, and eosinophilia, were suggestive of PE of hydatid cysts.…”

Pulmonary embolism due to cardiac hydatid disease: imaging findings of unusual complication of hydatid cyst

et al. 2002

We report two cases of primary cardiac hydatid cyst in which hydatid materials caused recurrent embolizations in pulmonary arteries and pulmonary parenchyma. Cardiac hydatid cysts may stay asymptomatic for a long time, until they reveal themselves being perforated into cardiac chambers and/or pulmonary artery or systemic circulation. The role of imaging techniques in diagnosis is discussed and the importance of dynamic enhanced CT, MR imaging, and enhanced MR angiography (MRA) is reported. Imaging findings were confirmed by surgery and pathology. Early diagnosis is essential because delayed treatment increases the morbidity and mortality rates.

“…According to the literature, the MRI features of angiosarcoma include heterogeneous signal intensity originating from intra-tumoral hemorrhage and heterogeneous enhancement [6,38]. Some unique characteristics on MRI were a cauliflower appearance on T1 SE [14] and a "sun-ray" appearance on enhanced MRI [39].…”

Role of magnetic resonance imaging for evaluation of tumors in the cardiac region

The aim of this study was to review the role of MRI in the assessment of heart neoplasm, 25 cases with heart neoplasm (10 myxoma, 6 rhabdomyoma, 5 angiosarcoma, 2 mesothelioma, 1 lymphoma, and 1 fibroma) were examined with MRI and echocardiography. Multislice T1- and T2-weighted spin-echo images and static gradient-echo images were taken in appropriate directions with electrocardiogram gating. Gadolinium enhancement was performed in 21 cases. Transthoracic echocardiography was performed in all cases. Except for the 5 patients with rhabdomyoma, the pathological diagnosis was obtained. MRI proved to be useful for tissue characterization of myxoma, angiosarcoma, mesothelioma, and fibroma in cases with tuberous sclerosis. MRI also proved to be useful for detection of the tumor, depiction of contour, relation with other cardiac structures, in cases with myxoma, angiosarcoma, mesothelioma, lymphoma, and fibroma. In the differential diagnosis, MRI provided important information in cases with myxoma, rhabdomyoma, angiosarcoma, and fibroma. In cases with tumors expanding into the mediastinum, such as mesothelioma and fibroma in this report, MRI was useful in determining the location and border. In cases with tumors adjacent to pericardium, MRI was useful in detecting pericardial invasion. Gadolinium enhancement added useful information in cases with myxoma, rhabdomyoma, angiosarcoma, and mesothelioma. The role of MRI with and without Gd enhancement differs somewhat in individual types of heart neoplasm, and adaptation must be considered in each kind of neoplasm. On the other hand, MRI is an essential examination in all cases with a cardiac mass, which has not been diagnosed, since it may provide useful information for the differential diagnosis.

“…On CT imaging, a low-attenuation, irregular, intracavitary mass is often shown, mostly involving the right atrial free wall 21,72 . The tumour can infiltrate the myocardium and cause obstruction, or it can also extend to directly invade the pericardial space and pericardium, causing pericardial thickening with or without effusion 21,72 .…”

Given the vascular nature of the lesion, angiosarcomas show a heterogeneous enhancement pattern with intravenous iodinated contrast 21 .…”

Pathology, imaging, and treatment of cardiac tumours

Cardiac tumours are a rare, but often devastating, clinical diagnosis. They encompass a broad set of lesions that include both neoplastic and non-neoplastic conditions. Cardiac tumours are often diagnosed incidentally during work-up for other conditions, or during ultrasound, CT, or MRI scans for unusual or nonspecific symptoms. In the past decade, important changes have been made in the nomenclature and the recommendations for diagnosis of cardiac tumours, as highlighted by the WHO's 2015 revision of the classification of cardiac tumours. Moreover, important advances in molecular genetics and therapeutics offer new approaches for the diagnosis and treatment of affected patients. In this Review, we provide an overview of the clinical, pathological, and imaging characteristics of all types of cardiac masses, including both benign and malignant primary cardiac neoplasms.
