Introduction
Primary cardiac tumors are exceedingly rare, occurring in about % of autopsies.
For primary cardiac tumors, about 75% are benign with myxoma accounting for at least half of reported cases and 25% are malignant. Of the malignant tumors, about 75% are sarcoma.

Objective
Define :
Characteristic imaging features of commonly encountered and selected cardiac tumors
Role of cardiac CT among noninvasive imaging options.

4. MEDIC
Materials and Methods
A review of primary cardiac tumors of cardiac CTA referred to the Medic Medical Center between 2013 and
All cardiac tumor patients were performed before and after the intravenous administration of contrast material.
Imaging characteristics of cardiac tumors were confirmed by operated on for cardiac tumors and histopathological features

5. MEDIC
Results
There’re 44(0.0024%) cardiac tumor patients of cardiac CTA patients
24 female and 20 male, mean age years.

The histopathological examination with Desmin (1+) , S100( 1+) and Vimenin (3+), EMA (-),Ki67 (15%) immunohistochemistry confirmed the diagnosis of Leiomyosarcoma

21. MEDIC
Conclusion
CT findings of cardiac myxomas are rarely specific, but pedunculated attachment with PPV 100%.
CT findings of cardiac sarcomas were broad based attachment, multi-lobular contour, Irregular or ill-defined margin, low attenuation, moderate to intense enhancement and heterogeneous, Intra-/extracardiac infiltration, pericardial and pleural effusion, metastasis
Cardiac CT is an alternative imaging modality to assess tumors
