Direct Extension of Bronchogenic Carcinoma Through Pulmonary Veins into the Left Atrium Mimicking Left Atrial Myxoma

Myxomas are rare tumours but are the most common benign tumours of the heart. They can arise from any heart chamber. However, they arise more frequently from the left atrium. They have rarely been described as originating in early age. A case of left atrial myxoma successfully removed using cardiopulmonary bypass in a 8-year-old child is presented. Review of the literature emphasizes the rarity and clinically aggressive behavior of this tumor in this age group. The object of this case report is to present myxoma in children and to evaluate possible differences between young and adult patients.

The Mean

We report the case of a 41-year-old female patient with symptoms of cerebrovascular accident manifesting with loss of consciousness during episodes of cough. Computed multislice chest tomography showed a 7.3- by 4.15-cm mass in the left atrium. A transesophageal echocardiogram showed a giant mass in the left atrium that passed through the mitral valve to the left ventricle, and severe obstructive stenosis was suggested by the mean transmitral gradient. After a comprehensive assessment of the mass, we decided to perform surgery. The pedunculated and fragile mass was attached to the interatrial septum with its handle, and the majority of it prolapsed through the mitral valve to the left ventricle and became stacked among the mitral valve leaflets. The removed mass was analyzed histopathologically and was found to be a myxoma. It is important for the cardiac surgeon to surgically remove an atrial myxoma because of the risks associated with embolization, including sudden death, as myxoma can block the blood supply from the atrium to the ventricle.

Intracardiac Masses

Background: Intracardiac malignancies are extremely rare and hard to detect or differentiate preoperatively.Case Report: We present a 48-year-old female patient who was diagnosed primarily with left atrial myxoma and taken into emergency surgery. The tumor extended into the pulmonary veins and infiltrated the atrial endocardium, and the histopathologic diagnosis was leiomyosarcoma. The left atrial endocardium was successfully peeled off with the tumor and complete resection was achieved.Conclusion: The possible malignant nature of intracardiac masses should be kept in mind, especially in middle-aged patients. The extent of the tumor must be determined in elective cases to establish the proper strategy for complete resection, which is the only chance of successful treatment for this lethal disease entity. Endocardial peeling is warranted for successful removal of the tumor mass in leiomyosarcoma.

Rheumatic Mitral Stenosis

Primary cardiac tumors are very rare. Atrial myxomas are the most common primary tumors and are commonly located in the left atrium. Myxomas can cause mitral valve inflow obstruction and can present with clinical signs and symptoms of mitral stenosis and the possibility of myxoma should be considered in differential diagnosis of mitral stenosis. Left atrial myxoma is rarely associated with rheumatic mitral stenosis. Transesophageal echocardiography plays a major role in the diagnosis of this tumor. We report a case of an extremely rare association between left atrial myxoma and rheumatic mitral stenosis. Because of its location and mobility, a thrombus in the left atrium may have a similar appearance to left atrial myxoma. However, a careful inspection of features of the left atrial mass may allow a diagnosis of left atrial myxoma. In our case, the site near the atrial septum, heterogeneous echogenicity, and detection of a stalk connecting the myxoma to the atrial septum were inspected. Such findings essentially exclude thrombus.

Myxomas are the most common benign tumors of the heart and are often locatedin the left atrium and interatrial septum. They are rarely seen in the right atriumand ventricles. Myxoma usually has a benign character, but when it reaches largevolumes it causes severe mechanical obstructive symptoms in patients. Shortness ofbreath, dizziness, cough, palpitation may be its symptoms. Also constitutional complaintssuch as fever, myalgia and weight loss can be seen in patients. This case isabout a 82-year-old female patient with large size atrial mxyoma that was detectedby echocardiography.
