A. Congestive heart failure due to myocardial infiltration.
B. Embolization of parts or pieces of the tumor.
C. Pericardial effusion/tamponade.
D. Valvular fenestration.
D: Valvular fenestration (a natural or surgically created opening in a surface)
- All the following statements concerning metastases of cardiac tumors are true EXCEPT:
A. Metastases are 10 to 40 times more likely than primary lesions
B. The most common metastatic tumor is a direct extension of lung and breast cancer
C. The most common metastatic tumor is myxoma

B. Patent foramen ovale
C. Pulmonary embolism
D. Systemic embolism
C
!!!
- An unattached, freely moving clot within the left atrium is referred to as a:
A. Ball thrombus
B. Pedunculated thrombus
C. Sessile thrombus
D. Stationary thrombus
A: Ball thrombus
*note: sessile - immobile, fixed in one place
!!!
- A thrombus shape that is associated with embolization is:
A. Spherical
B. Flat
C. Eccentric
D. Pedunculated
D. Pedunculated
!!!

A. Angiosarcoma
B. Fibroelastoma
C. Lipoma
D. Myxoma
B. Fibroelastoma
*379. A primary benign cardiac tumor that is found most often on the endocardial surface of the atrioventicular valves or valvular endocardium is:
A. Fibroma
B. Lipoma
C. Myxoma
D. Papilloma
D. Papilloma
- The most common primary benign cardiac tumor found in children is:
A. Myxoma
B. Papilloma
C. Rhabdomyoma
D. Rhabdomyosarcoma
C
!!!
- The most common primary benign cardiac neoplasm is:
A. Fibroma
B. Lipoma
C. Myxoma
D. Papilloma
C. Myxoma
!!!
- A dumbbell-shaped configuration of the interatrial septum is associated with:
A. Amyloidosis
B. Lipomatous hypertrophy
C. Sarcoidosis
D. Sarcoma
B. Lipomatous hypertrophy
The most common location for a pericardial cyst is the:
A.Hilium
B.Left costophrenic angle
C. Right costophrenic angle
D. Superior mediastinum
C. Right costophrenic triangle
*note: The cardiophrenic angle is the angle between the heart and the diaphragm
Pericardial cysts (PCs) are uncommon benign congenital anomalies residing in the middle mediastinum. The location of PCs is diverse with 70% of cases in the right cardiophrenic angle, 22% in the left cardiophrenic angle, and 8% in the posterior (as in our case) or superior anterior part of the mediastinum.
