Abstract: Here, we report an unusual case of left atrial myxoma presented with morphology of cavernous hemangioma supplied by the right coronary artery. Surgical resection of the left atrium myxoma was performed, and the patient experienced an uneventful recovery during hospitalization.

Background Cardiac myxomas are the most common primary benign tumors of the heart usually presenting as an oval mass attached to the interatrial septum. Mild heterogenous enhancement is typically seen upon contrast administration. Myxomas are benign, however can present with embolic episodes necessitating prompt diagnosis and treatment. Case presentation A middle-aged woman presenting with acute ischemic stroke was detected to have a complex cystic mass in the left atrium on echocardiography. Further evaluation with cardiac magnetic resonance imaging narrowed a differential diagnosis to hemangioma, hemangioendothelioma, sarcoma, hydatid cysts, bronchogenic cysts, and cystic variant of cardiac myxoma. CTA demonstrated arterial supply from the left circumflex artery supplying the lesion. Following surgical excision, histopathology analysis suggested a cystic cardiac myxoma with secondary degeneration. Conclusion Cystic masses in the heart are challenging to diagnose due to similar imaging characteristics, and misdiagnosis may lead to further major downstream complications such as stroke, hemorrhage, and hemodynamic alterations causing syncope. Therefore, surgical excision of a cystic cardiac mass is justified to establish a definitive histopathological diagnosis and prevent further downstream complications. We hereby report a rare case of cystic cardiac myxoma in the left atrium showing intense progressive enhancement in CMR and CTA in a middle-aged woman presenting with acute stroke. This case highlights an exceedingly rare variant of cystic cardiac myxoma.
