From: Metastatic cardiac tumors: from clinical presentation through diagnosis to treatment
Im: Case no. 4: Metastatic testicular germ cells tumor in the liver with thrombus of the right atrium - Imaging. a – Contrast enhanced CT coronal reconstruction showing a hypodense right atrium mass (arrow). b - Contrast enhanced CT sagittal reconstruction demonstrating the hypodense right atrium mass (arrow) continuing into the IVC (asterisk). c – Cardiac MRI steady stated free precession sequence (“bright blood”): a plane through the right atrium and IVC. A hypointense mass is demonstrated in the right atrium (arrow) protruding into IVC (asterisk). d - Cardiac MRI T2 sequence: a plane through the right atrium and IVC- a hyperintense mass is demonstrated in the RA (arrow) protruding into IVC (asterisk). Fig. 4 H: Case no. 4: Metastatic testicular germ cells tumor in the liver with giant thrombus of the right atrium - Histology. a Most of the cardiac mass consisted of amorphic eosinophilic material, seen in the upper part, representing fibrin of a thrombus. Foci of initial thrombus organization are seen at the bottom, HE X40. In the areas of initial thrombus organization b) and c) spindled mesenchymal cells are present, haphazardly arranged. Unlike in myxoma, these mesenchymal cells do not create cords, vascular channels or nests. B – HE X100, C – HE. X400. (HE = Hematoxylin and Eosin stain)
