title: Pulmonary vein tumor thrombosis and left atrial extension in lung carcinoma.
abstract: A case of lung carcinoma extending into left atrium through a pulmonary vein and mimicking left atrial myxoma is presented. The localized enlargement of a pulmonary vein is seen as a possible CT sign of pulmonary vein tumor thrombosis. Computed tomography (CT) and echocardiography are complementary in the correct diagnosis of this condition.
