“…This was the TTE nding of our young patient in whom a TTE was performed as part of the etiological assessment of her ischemic stroke. TTE may show no signs in 36% of cases and transesophageal echocardiography is a good option for a better and more accurate description of the tumor, its location, and attachment with a sensitivity close to 100% [6,15]. MRI and/or cardiac CT scan can help in the tissue characterization of the mass, its exact location, and cardiac anatomy and therefore valuable support for the surgical approach [1,4].…”

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. The brain CT scan and magnetic resonance imaging have revealed cerebral ischemia located in the right Sylvian territory. Transthoracic echocardiography highlighted a round cardiac mass, mobile, heterogeneous, multilobed, appended to the interatrial septum and the atrial side of the large mitral valve by wide implantation and measuring 38x25mm 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. Conclusions: 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.

“…These benign cardiac tumors are frequently found in the left atrium (LA) and produce diverse symptoms that can be related to the tumor size, tumor position, and the presence of any obstruction of the normal function of the heart. Even though these are benign tumors, they might cause serious consequences, including embolization, interruption of blood flow, and then, subsequently, heart failure [ 1 ]. This means that early detection and treatment, being the main approach, are essential for tackling this issue.…”

Misattribution of Dyspnea: Unveiling Atrial Myxoma as the True Culprit

Cardiac myxomas are the most common primary tumors of cardiac neoplasm, predominantly originating within the left atrium (LA). In the present case, a 41-year-old male, identified as a heavy smoker for 15 years, previously diagnosed with chronic obstructive pulmonary disease (COPD) and currently undergoing treatment, presented with a history of dyspnea persisting for one year. Initially, the patient presented to the internal medicine outpatient clinic and was diagnosed with an exacerbation of COPD, but subsequent evaluation revealed the presence of a large mobile pedunculated mass situated in the LA using echocardiography. Subsequently, the mass was surgically excised using a median sternotomy approach. The histopathological examination confirmed cardiac myxoma. This occurrence underscores the significance of considering cardiac myxoma as a plausible differential diagnosis in instances of dyspnea to avert potential complications.
