Diagnosing a mass in the left atrium can be difficult. The most frequent differential diagnoses are primary or metastatic tumors, vegetation, and thrombi. We report a case of a left atrium mass found in a 57-year-old man, with a history of a non-operable squamous cell lung cancer. The control chest scanner showed a defective opacification of the left atrium. The TTE revealed a dilated left atrium with the presence of a large atrial mass. Despite a considerable portion of the left atrium being occupied by the tumor, the patient maintained sinus rhythm and showed no symptoms. The cardiac MRI concluded to a large left atrial myxoma. The patient was subsequently transferred to the cardiovascular surgery department where he underwent resection of this mass and the anatomo- pathology confirmed the diagnosis of myxoma. The relevance and value of TTE for a precise diagnosis of cardiac myxoma, while cancer lung metastasis is highly suspected, is shown by our case.
