Abstract
Introduction: Left atrial myxoma is a rare benign tumor. It can be an embolic complication such as an ischemic stroke. Case presentation: It was a 48 years old patient who was referred to our unity for the etiological investigation of an ischemic stroke. She did not have personal medical and surgical history. She had a recent right hemiplegia. The cardiac auscultation found a mitral diastolic murmur. The brain CT showed a recent ischemic stroke in the superficial and deep left sylvian territory. The transthoracic echography revealed a myxomatous mass, responsible of an obstacle of the left ventricular filling. Anticoagulation by antivitamin K (AVK) had been initiated and a resection of the mass indicated. Conclusions: The left atrial myxoma is a rare benign tumor whose mode of revelation can be an embolic complication. The Echocardiography is reference imaging modality in diagnosis with a high sensitivity.
Highlights
Left atrial myxoma is a rare benign tumor
The systemic embolization rate reported is between 30 to 45% of myxomas of the left atrium and this frequency can go up to 64% when it extends to the left ventricle [3]
The left atrial myxoma is responsible for only 0.5% of cases of ischemic stroke [2,3]
Summary
The left atrial myxoma is a rare benign tumor. It is the most common cardiac primary tumor. It is more often found in women [1]. The left atrial myxoma is responsible for only 0.5% of cases of ischemic stroke [2,3]. We report a case of a left atrial myxoma revealed by a stroke in a woman. Case Presentation It was a 48 years old patient who was referred to our unity for the etiological investigation of an ischemic stroke. She did not have personal medical and surgical history.
