Echocardiography and CT revealed that a left atrial mass initially suspected as a myxoma in a 73-year-old man was an extension of a pulmonary tumor through the pulmonary vein.
Case Report (n=1)
Primary lung carcinoma can rarely extend into the left atrium via the pulmonary vein, mimicking a cardiac myxoma on initial echocardiography.
Left atrial (LA) mass is most commonly presumed to be a cardiac myxoma, as it is approximately 75% of primary cardiac tumors, with a strong predilection for the LA. In rare instances, primary lung carcinoma may extend to the LA, creating an intracardiac mass indistinguishable from a myxoma on initial echocardiographic assessment. We report a Persian 73-year-old man with progressive dyspnea and a left atrial mass initially suspected as a myxoma. Echocardiography and CT revealed extension of a pulmonary tumor into the atrium through the pulmonary vein. This case highlights the diagnostic and treatment challenges of intracardiac extension, which is rare but should be considered by the cardiologist.
Mirdamadi et al. (Tue,) conducted a case report in Left atrial mass / Lung carcinoma (n=1). Echocardiography and CT revealed that a left atrial mass initially suspected as a myxoma in a 73-year-old man was an extension of a pulmonary tumor through the pulmonary vein.
