“…Embolic events occur in approximately 40-50% of patients with CM often to the brain due to fragments of the myxoma itself or surface emboli. In addition, embolization to the kidneys, spleen, aortic bifurcation, and the lower extremities is not infrequent [7]. Similarly, our patient had bilateral renal and splenic infarct due to tumor embolization along with the PICA territory infarct of left cerebellum and pons.…”

Background: Atrial myxoma remains a rare clinical entity with an incidence of surgically resected cases of 0.5-0.7 per million population and prevalence of < 5 per 10,000. It typically manifests in woman after third decade of life; symptoms vary greatly and may present with arrhythmia, intracardiac flow obstruction, embolic phenomenon, and associated constitutional symptoms. Neurological complications associated with atrial myxoma most frequently include cerebral infarct due to embolus. Cerebellar involvement is very rare and only a few cases have been reported in the literature. Case presentation: A 55-year-old Brahmin man with no history of diabetes mellitus and hypertension, presented with complaints of dizziness, headache, vomiting, double vision, and unsteadiness of gait for 2 weeks. His headache was sudden in onset, of a pulsating type and localized on left temporal side. Vomiting was projectile and bilious. Double vision was present in all directions of gaze and he had uncoordinated movement of his body and tilting to the left side. On examination, his cerebellar functions were impaired. He was thoroughly investigated for the cause of stroke after abnormal magnetic resonance imaging results with normal computed tomography angiography of his brain. Echocardiography and computed tomography of his chest showed a mass attached to intra-atrial septum and prolapsing through mitral valve, which was suggestive of left atrial myxoma. Five days following admission, he developed abdominal pain due to thromboembolism causing splenic and renal infarct. Conclusion: Although rare, atrial myxoma has to be considered a cause of stroke and other embolic phenomenon causing multiorgan infarctions. Early and timely diagnosis of the condition can prevent further recurrence and inappropriate anticoagulant therapy. It would be pertinent to have echocardiography done in patients who present with a stroke, arrhythmias, and other constitutional symptoms. The tumor once detected must be removed surgically as early as possible, which not only reduces serious thromboembolic complications but can be potentially curative.

Background Primary cardiac tumors are rare, and approximately 90% of them are benign. Myxoma is the most common type of these tumors occurring in the left atrium in 75–85% of cases. The tumor can cause the left atrio-ventricular valve obstruction and embolization phenomenon. Case presentation We reported a case of 54-year-old man with complaints of dyspenea and amnesia. In our patient, transthoracic echocardiography revealed a mass of 28*63 mm attached to the upper intra-atrial septum, which was prolapsing through the mitral valve into the left ventricle during diastole, being indicative of the left atrial myxoma. On examination, he was alert and conversant, and no pathological abnormality was observed in the examination of cardiovascular, gastrointestinal, respiratory, hepatic, renal and nervous systems. After myxoma diagnosis, the tumor was removed under cardiac surgery and discharged under good conditions. In the telephone follow-up after discharge, the patient recovered and did not report the disease and surgery complications. Conclusions Patients with cardiac myxoma are usually asymptomatic, but they may have manifestations related to the embolism phenomenon or intracardiac obstruction. Therefore, myxoma may represent an emergency. Surgery should be performed as soon as possible. If surgery is delayed, the patient may suffer from serious and irreversible complications, such as stroke and cardiac arrest.

“…Most cardiac myxomas occur in the left atrium and arise in the area of the fossa ovalis. 8 Complications of myxomas include thrombosis and emboli, atrial or ventricular arrhythmias, and atrioventricular valve obstruction. 7 The symptoms observed may be related to tumor location and size.…”

Cardiac myxoma is rare in children. Myxomas are exceedingly rare in infancy. Right atrial myxomas were recorded in a small number of case reports involving infants worldwide. We report the case of a 2-month-old infant with giant right atrial myxoma. The case presented to our hospital with respiratory distress, and had pericardial and pleural effusion. Diagnosis of cardiac tumor was made with the aid of computerized tomography scan and echocardiogram. The tumor size was 3.1 × 3.4 × 3.9 cm. The patient worsened rapidly and had sudden cardiac arrest which did not respond to interventions. Postmortem cardiac autopsy confirmed the diagnosis of myxoma on gross examination and histology. This article aims to focus attention to the atypical size and location of this atrial myxoma, causing diagnostic difficulty in this infant.
