Giant Left Atrial Myxoma Revealed by Neurological Manifestation in a Young Female Patient

Abstract

Cardiac myxoma is a prevalent benign neoplasm that arises inside the cardiac tissue and exhibits a gradual growth pattern. The annual incidence rate of cardiac myxoma is approximately 0.5–1 cases per 1,000,000 persons. The fragmentation of a cardiac tumor may be influenced by cerebrovascular events. Ischemic stroke is a relatively infrequent occurrence in pediatric populations and can occasionally be attributed to cardiac myxoma. In instances of ischemic stroke, neurological impairments are observed as a result of emboli or thrombi originating from the myxoma. Echocardiography is a valuable tool for promptly diagnosing myxoma and facilitating immediate surgical removal of the myxoma. We report a 17 years old female with neurological deficit weakness in the upper and lower right extremities since 2 months ago as the chief complaint with intermittent shortness of breath. Haemodynamic parameters was stable. The patient underwent brain imaging with result a lesion of the left lentiform nucleus, transthoracic echocardiography and trans esophageal echocardiography with oscillating septated mass on left atrial, attached to the anterior mitral leaflet (AML). Primary cardiac tumors are a very uncommon cause of cardiac embolic events. An atrial myxoma, a benign growth, can form on either the left or right side of the upper part of the heart. Untreated atrial myxoma can lead to adverse effects such as arrhythmia, pulmonary edema, and emboli formation that obstruct blood flow in the heart's veins. Ischemic stroke causes a specific functional impairment. Neurological symptoms in stroke can be an extra cardiac manifestation of atrial myxoma. The use of transthoracic and tran seso phageal is important in diagnosing atrial myxoma.
