Coexisting left atrial myxoma-like mass and pulmonary vein metastatic component of adrenocortical carcinoma presenting with cardioembolic stroke: a case report
Year: 2026
Type: article
Study design: Case Report
Abstract: Background: Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy with a strong tendency for early metastatic dissemination. Cardiac metastases are exceptionally uncommon and usually occur through tumor extension via the inferior vena cava into the right atrium, rather than as isolated left-sided involvement. Intracardiac metastases may mimic primary cardiac tumors such as atrial myxomas, creating diagnostic challenges and increasing the risk of systemic embolization. Case presentation: A patient with a history of ACC presented with transient neurological deficits consistent with cardioembolic stroke. Brain magnetic resonance imaging demonstrated multiple acute embolic infarcts. Transthoracic and transesophageal echocardiography revealed two distinct left atrial masses, one attached to the interatrial septum and another highly mobile lesion extending toward the left superior pulmonary vein. Management and outcome: Urgent surgical intervention was performed due to the high embolic risk. Both lesions were completely excised, and histopathological examination confirmed metastatic ACC. Conclusion: Cardiac metastases should be considered in patients with ACC who present with embolic events and left atrial masses.
