Sandbox: table diagnosis myxoa
The table below summarizes the findings that differentiate Cardiac Myxoma from other conditions that cause Emboli and hemorrhage:
| Imaging Technique | Features | Sensitivity | Specificity | Limitations |
|---|---|---|---|---|
| Two- or three-dimensional echocardiography | B | C | D | E |
| MRI | Cardiac myxomas appear spherical or ovoid with lobular contours, irregular in shape.
T1: tend to be low to intermediate signal, but areas of haemorrhage may be high T2: can be variable due to heterogeneity in tumour componants; e.g calcific components > low signal; myxomatous components > high signal GE (gradient echo): may show blooming of calcific components T1 C+ (Gd): shows enhancement (important discriminator from a thrombus) demonstrates uniform heterogeneous enhancement. |
C | D | E |
| CT | Intracardiac heterogeneously low attenuating mass. The attenuation is usally lower than that of myocardium, coarse dystrophic calcification is common. | C | D | E |
| Angiography | B | C | D | E |
| Chest x-ray | Results can be normal. Otherwise, common findings include cardiomegaly, left atrial enlargement, vascular redistribution, prominent pulmonary trunk, and intracardiac tumoral calcification(rare). | C | D | E |
