“…Myxoma is a sporadically occurring cardiac tumour affecting all groups, but commonly encountered in the third to sixth decades, with female preponderance [4]. The presentation is quite protean, ranging from asymptomatic, non-specific constitutional symptoms to various cardiovascular manifestations including embolic phenomenon.…”

“…Myxomas can be quite large, occupying most of the left atrium resulting in obstruction to left ventricular filling, while prolapse of a tumor through the mitral valve may result in the destruction of the annulus or valve leaflets causing mitral valve regurgitation [3]. It occurs sporadically in Case Reports in Clinical Medicine all age groups, mostly between the third and sixth decades, and women are more commonly affected than men [4] [5]. Myxomas are slowly growing and usually remain asymptomatic and incidentally discovered in about 20% of cases [6].…”

Myxoma is a benign and the most frequent tumor of the heart, accounting for approximately 30% of all primary cardiac tumors. Seventy five percent of atrial myxomas are in the left atrium. We present a case of a 20-year-old house wife presenting with biventricular heart failure and chest infection five months after her last child birth. Transthoracic echocardiography showed a mobile left atrial echogenic mass measuring 4.6 × 4.0 cm attached to the interatrial septum. Left ventricular systolic function was mildly reduced (EF 48%) with mitral and tricuspid incompetence. A diagnosis of left atrial myxoma with biventricular heart failure with chest infection was made. She improved on antibiotics and treatment of heart failure, and referred to Aminu Kano Teaching Hospital for further management.

“…Ischemic strokes associated with myxoma of the left atrium have been described even in the pediatric population but represent only 0.5% of all strokes. The third group of symptoms that make up the triad is related to the obstruction of the mitral valve by myxoma, which leads to dyspnea, dizziness, or even syncope or sudden death [1,[4][5]15]. Transthoracic echocardiography (TTE) is the non-invasive imaging modality of choice, to be performed in patients with a stroke to eliminate the cardioembolic origin [7,[16][17][18].…”

“…Histological analysis of the removed tumor is the gold standard to confirm the diagnosis by highlighting a myxoid proliferation of cells expressing calretinin in immunohistochemistry. Cardiac myxoma is a histologically benign tumor resulting from the proliferation of multipotent mesenchymal cells of the oval fossa [15,18,23], it presents a risk of recurrence of 1 to 5% after inadequate surgical excision. Recurrence occurs for poorly differentiated active myxomas [4,5].…”

Introduction: Cardiac myxoma is a primary benign tumor most often located in the left atrium and it is a rare source of cerebral stroke of young subjects. Case Presentation: We report the case of a young women with cardiac myxoma revelated by hemiplegia. The patient suddenly presented vertigo followed by a fall, a heaviness of her left body, and dysarthria. Brain CT tomography and magnetic resonance imaging revealed cerebral ischemia in the right Sylvian territory. Transthoracic echocardiography revealed a round cardiac mass, mobile, heterogeneous, multilobed, appended to the interatrial septum and the atrial side of the large mitral valve by wide implantation, measuring 38 x 25mm in the parasternal short axis (PSAX) and apical 4 chamber views evocative of left atrium myxoma. After the surgical resection, which was postponed for a month, the removed tumor was sent for histopathological examination. The morphological examination revealed a myxoid tumor proliferation compatible with cardiac myxoma expressing calretinin by these tumor cells in the immunohistochemical study. Conclusion: Left atrium myxoma is a benign cardiac tumor and a rare cause of ischemic stroke. Transthoracic echocardiography facilitates the diagnosis of this tumor which will then be confirmed by histological analysis.
