Significance of Microbubble Contrast Study in Identification of Right Atrial Masses

Background: Cardiac masses are exceptionally rare but pose the most dangerous threat to the human body.They may be benign, malignant or tumor-like conditions such as thrombus or extracardiac cysts.The classification of these lesions is an important predictor of mortality.Several factors are considered helpful in establishing a diagnosis and treatment plan such as the location of the mass, age at presentation and imaging characteristics.Left atrium is the most common cardiac mass entity.However, a mass in the right atrium creates unique challenges because of the presence of normal anatomic variants that can mimic a tumor.Right atrial masses are rare and cannot be diagnosed unless a histopathological specimen is obtained.Here we present a case of a female, with two right atrial masses, highlighting the diagnostic challenges in arriving at a definitive diagnosis.
