Overview
There are no specific chest x-ray findings associated with cardiac myxoma, the results can be reported as normal.
Chest x-ray
There are no specific chest x-ray findings associated with cardiac myxoma, the results can be reported as normal. [1] Related imaging findings include cardiomegaly, left atrial enlargement, vascular redistribution, prominent pulmonary trunk, and intracardiac tumoral calcification (rare).

Lateral chest radiograph from a 16-year-old girl with syncope and bacterial endocarditis. The radiograph demonstrates two areas of dense calcification (arrowheads) overlying the posterior aspect of heart. The posterior-anterior (PA) view confirmed location in the heart (not shown). At surgery a calcified myxoma of the right atrium was removed.
