[Computer tomographic and echocardiographic diagnosis of intracardial space occupying masses]
Insights
Echocardiography and computed tomography (CT) can detect cardiac masses, but differentiating thrombi from tumors requires careful analysis of location and morphology. Neither imaging technique is foolproof for diagnosing cardiac thrombi.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Intracavitary cardiac masses pose diagnostic challenges.
- Distinguishing between cardiac thrombi and tumors is crucial for appropriate patient management.
Purpose of the Study:
- To evaluate the utility of echocardiography and computed tomography (CT) in diagnosing intracavitary cardiac masses.
- To assess the ability of these imaging modalities to differentiate between cardiac thrombi and tumors.
Main Methods:
- Nineteen patients with suspected intracavitary masses underwent both echocardiography and CT.
- Ventriculography was used as a diagnostic reference when necessary.
Main Results:
- Echocardiography identified a mitral valve thrombus missed by CT, initially misdiagnosed as a tumor.
- Both methods yielded occasional false negatives for cardiac thrombi.
- CT showed potential in differentiating thrombus from tumor if the tumor contained fat or was cystic.
Conclusions:
- Echocardiography and CT have complementary roles in evaluating intracavitary cardiac masses.
- Differentiation between thrombus and tumor relies heavily on location, patient history, and morphological features.
- Neither echocardiography nor CT alone can definitively rule out cardiac thrombi.
Abstract:
Nineteen patients suspected of having intracavitary masses were examined by echo-cardiography and computer tomography. One 1 cm. thrombus on the mitral valve could be demonstrated only on the echo-cardiogram and was interpreted as a tumour. Both CT and echo-cardiograms produced occasional false negative findings with cardiac thrombi, which were ultimately diagnosed by the other method or by ventriculography. Differentiation between a thrombus and a tumour depends essentially on its localisation and on the history, and some morphological criteria. Echo-cardiography and densitometric measurements did not assist in the differential diagnosis. CT may be able to differentiate thrombus from tumour if the latter contained fat or has become cystic.
