Purpose or Case Report: Teaching Points:
1. Review the imaging approach and differential diagnosis for cardiac masses in children
2. Illustrate the characteristic imaging findings of benign and malignant pediatric cardiac tumors and understand the spectrum of pseudotumors that may be encountered in pediatric cardiac disease.
3. Discuss the screening guidelines and management approach to cardiac masses in children with predisposition syndromes.
4. Review radiologic-pathologic correlation for cardiac masses and pseudomasses in children.

Outline:
1. Review our institutional experience, including the relative frequency of cardiac masses and pseudomasses
2. Describe the recommended imaging protocols for screening, surveillance, and characterization of cardiac masses on echocardiography, CT, and MRI
3. Describe the imaging findings at echocardiography, CT, and MRI in the spectrum of pediatric cardiac tumors and pseudotumors in:
a. Predisposition syndromes: Tuberous sclerosis, Nevoid basal cell carcinoma syndrome, Carney complex, etc.
b. Primary malignant cardiac tumors: Rhabdomyosarcoma, angiosarcoma, malignant fibrous histiocytoma, fibrosarcoma, etc.
c. Secondary cardiac tumors: Osteosarcoma, hepatoblastoma, neuroblastoma, Ewing sarcoma, synovial cell sarcoma, etc.
d. Benign cardiac masses: Mature teratoma, vascular malformations, lipoma, myxoma, fibroma, etc.
e. Cardiac pseudomasses and mimics: Thrombus, Epicardial/myocardial fat necrosis, pseudoaneurysms, granulomatous disease, etc.
4. Provide radiologic-pathologic correlation for cardiac masses and pseudomasses in children
