- Cardiac myxoma is a benign neoplasm that represents the most common primary tumor of the heart, accounting for approximately 30% of all primary cardiac neoplasms.
- Most affected patients present with at least one feature of a classically described triad that includes cardiac obstructive symptoms, constitutional symptoms, and embolic events.
- Because the clinical presentation of patients with cardiac myxomas is diverse and nonspecific, imaging plays a key role in establishing the diagnosis.
- 90% occur on the left
- 90% are solitary
- Myxomas may calcify
 Differential Diagnosis
 Imaging Findings
- Myxoma typically manifests as a polypoid, intracavitary left atrial mass that arises from the interatrial septum, but it may originate in any cardiac chamber.
