Right ventricular myxoma in a 12-year-old child: a case report.
Cardiac myxoma especially of the right ventricle, is rare in children. A 12-year-old boy with right ventricle myxoma is reported. His heart murmur was found incidentally when he visited the Outpatient Department (OPD) because of upper respiratory infection symptoms. There was no exertional dyspnea, no palpitation, no syncope and no skin lesion. The echocardiogram revealed a heart tumor of about 4 x 3 cm in the right ventricle (RV) extending to the right atrium (RA). The tumor grew from the interventricular septum, resulting in an RV outlet and inlet obstruction. Magnetic resonance image (MRI) revealed a well-defined mass in the RV ventricle, with good enhancement after injecting a contrast medium. The patient received right atriotomy and total excision of the tumor with repairing of the interventricular septum base. Pathology revealed myxoma with gelatinous whitish color and central hemorrhage. At post-operative follow-up, the patient's condition was good.
