CTICasesLeft Atrial Myxoma with Organizing Thrombus
Imaging findings
CT chest shows a hyperdense mass in the left atrium, with associated bilateral pleural effusions and signs of systemic heart failure.
Key takeaways
Myxomas can occasionally present as hyperdense masses on non-contrast CT due to organizing thrombus on the tumor surface. Their presence can trigger mitral valve obstruction, leading to post-capillary pulmonary hypertension, pulmonary edema, and pleural effusions.
