“…MR images may demonstrate hemorrhage as hyperintense foci on T1-weighted images. Areas of central necrosis and hemorrhage are characteristic findings and result in heterogeneous signal intensity on T2-weighted images [6,7,18,56]. Intravenous contrast administration usually demonstrates avid enhancement [13].…”

“…Intravenous contrast administration usually demonstrates avid enhancement [13]. In cases of pericardial infiltration, a "sunray appearance" may be seen as a result of linear enhancement along vascular spaces [56]. Tumor invasion to the pericardium usually appears as a sheet-like thickening of the pericardium and the presence of pericardial effusion [53].…”

Cardiac tumors are uncommon, with primary cardiac tumors being exceedingly rare. Benign primary cardiac tumors are more common than malignant primary cardiac tumors. Common benign cardiac tumors include myxoma, lipoma, papillary fibroelastoma, rhabdomyoma, fibroma, hemangioma, and paraganglioma. Malignant cardiac tumors include metastasis, angiosarcoma, rhabdomyosarcoma, and lymphoma. Clinical presentation depends on tumor pathology, location, and hemodynamic effects. Echocardiography, computed tomography, and magnetic resonance imaging often play a key role in differentiating between benign and malignant tumors, assessing the extent of tumor involvement, presurgical planning and management, and postoperative follow-up of cardiac masses.

“…Tumours are exophytic and extensively infiltrate the atrial wall. The pericardium may be involved and present as haemopericardium [9,10]. Extensive pericardial involvement has been described as a`cauliflower' appearance [6].…”

“…Angiosarcoma is characterized by intratumoral bleeding, a nodular or cauliflower appearance, non-homogeneous enhancement on post-contrast studies and prominent homogeneous enhancement on the surface of the lesion. Thè sunray' appearance of pericardial involvement on enhanced MRI has been documented [10].…”

We report a case of primary heart angiosarcoma and its appearance on plain and post-contrast computed tomography and magnetic resonance imaging in 21-year-old woman. The tumour involved the right atrium, expanded superiorly among the superior vena cava, ascending aorta and innominate vein, and infiltrated the pericardium. The tumour was disseminated into lungs, liver and bones at the time of its clinical presentation.

“…10,49 A "sunray" appearance of lines from the endocardium to the pericardium of enhancement with gadolinium contrast representing areas of hemorrhage has also been described. 53 Melanoma may have high signal intensity on T 1 -weighted sequences due to paramagnetic metals bound by melanin. 54,55 Mesothelioma appears homogenously isointense on T 1 -weighted images and heterogenous on T 2 -weighted images due to areas of necrosis and enhances with gadolinium contrast administration.…”
